2014/12/05-08 (F-M) On To Texas

2014/12/05 (F) Parting Company (for now)

A set of standing jokes with us involves our answers to the question “what time is it?”  The most common response is the day of the week, such as “Friday” (if we know what day it is) or perhaps “I think it’s Friday” (if we are less sure).  Variations include “daytime” or “nighttime” both of which only restate the obvious but at least we are usually correct, or perhaps “morning,” “afternoon,” or “evening” if we are trying to be more precise.  More globally we might answer “eastern” or “central” referencing the time zone we (think) we are in.

I was awake and ready to get up at 5:30 AM (technically the morning but still dark as night).  I checked the house batteries and they were down to 66% SOC (State Of Charge).  The coach had been running on the batteries/inverter since 9 PM last night, so 8.5 hours.  At 3.6 percentage points per hour I expected a 31 percentage point drop to around 60% SOC, so this charge level seemed reasonable, except that we had very few things running last night.  The refrigerator and auxiliary air-compressor were on, of course, although the air-compressor only runs for a few minutes every couple of hours and the fridge runs around 20-24 minutes per hour.  The Aqua-Hot was turned on but I did not hear the fans come.  I had the thermostats set to 15 (Celsius, 59 Fahrenheit) before we went to bed and the temperature in the coach this morning was in the upper 60s, so I don’t think any of the zone pumps or heat exchanger fans came on overnight.  In other words, it seemed to me that we had used more charge from the batteries than we should have.  Although I installed the 24 VDC battery bank and the new Magnum inverter/charger two years ago, we have not done very much boondocking (dry camping, no hookups) so we are still figuring out the finer points of this system.

I started the GenSet and the charger came on in bulk charge mode delivering 89 Amps to the battery bank at 29.1 VDC.  It switched to absorption mode fairly quickly and by 7:30 AM it was delivering 34 Amps at 28.3 VDC and the SOC was up to 86%.  The battery bank has a 400 A-Hr capacity (at “24” VDC, which is actually 25.4 VDC when fully charged) so 10% of that is 40 A-Hr and the generator had returned approximately 80 A-Hrs of charge at 24VDC to the battery bank.  (“A-Hr” stands for Ampere-Hours and is actually a measure of energy, specifically electrical charge, which technically should be stated in Coulombs.)  “40 A-Hr” means a steady flow of current at a 40 Amp rate for one hour.  Note, however, that this also depends on the voltage.  40 A-Hr for a nominal 24 VDC system is twice the energy of 40 A-Hr for a nominal 12 VDC system.  Most RVs are set up with a nominal 12 VDC house battery system.  Our house battery bank is thus equivalent to an 800 A-Hr, 12 VDC system.)

The downside to all of this is that conventional lead-acid batteries, including our AGM batteries, do not tolerate very well being repeatedly discharged below 50% SOC, so the effective/useable capacity is about 1/2 of the stated capacity.  The more deeply the batteries are drained the fewer times they can be brought back up to full charge. Whereas shallow discharging allows for more cycles, and more total energy in and out, but requires a larger battery system to provide power for a reasonable amount of time.  Batteries are heavy and bulky, so you cannot just take as many as you would like.  For lead-acid batteries 50% discharge seems to be the optimal compromise for battery life, useful run time, and size/weight.

We were up early enough to have a light breakfast and a cup of coffee and have time to digest our meal before we started driving.  I powered on our Verizon MiFi and my computer and downloaded e-mails while Linda used her iPad to preview the truck stop options at the interchange just this side of Little a Rock, Arkansas.  She also pulled up the satellite image of the Wal-Mart in Texarkana, Texas where we planned to spend the night.  Cellular access to the Internet, mapping programs, and satellite imagery, along with GPS receivers have changed the nature of motor vehicle travel in general and RVing in particular.  There are certain things where the element of surprise associated with discovery is a good thing, such as an unexpected view when hiking, but when it comes to maneuvering a 40 foot motorcoach with a 20 foot car/towbar attached to its rear end surprises are usually not a good thing.

Around 8 AM we stepped outside and saw Fonda outside with their two dogs (Rascal and Daffy) so we walked back to their bus.  Butch was on the phone with U. S. Coach in New Jersey discussing the main engine air-compressor situation.  They confirmed that the unloader valve(s) are a common failure point and that the replacement parts were inexpensive and available.  He ordered four sets for delivery to Amarillo, Texas where they will be visiting someone while we are in Alvarado, Texas.  Two sets are for them and two sets are for us.  The parts may not make it to Amarillo until Wednesday, so we will be as flexible in our travel planning as we can.  If Donn will let us stay at his place in Alvarado, Texas we may just sit there, unhook the car, and go explore the area.

By 8:30 AM the house battery charger was showing zero (0) Amps at 25.3 VDC, indicating that the batteries were fully charged.  The Magnum Battery Monitor Kit (BMK), however, was showing the SOC as 88%.  I am inclined to believe that in this case the BMK is not showing the correct SOC, but I will keep a close eye on this.  When we get to Donn’s place we will be plugged into a “50 Amp” RV electrical service for at least 40 hours and see what that does to the readings.

While Butch and Fonda had breakfast we went for a stroll around the Wal-Mart parking lot to stretch our legs and scoped out the best egress route.  Around 9 AM we started preparing the interior for travel and by 9:45 I had the car prepared for towing and the main engine running.  We pulled out at just before 10 AM and took the lead.  I drove the first 80 miles at 55 MPH due to light to moderate rain and greatly reduced visibilities.  We took exit 161 just east of Little Rock, Arkansas and pulled into a Love’s Truck Stop.  Butch picked a better lane than I did and we ended up leaving and driving to the Pilot Truck Stop on the other side of the highway.  But before we left Linda walked over to let them know what we were doing and say “so long, see you down the road.”  Two miles after we got back on the highway we stayed left for I-430 around the south side of Little Rock while Butch and Fonda stayed on I-40 around the north side of the city.  We were headed to I-30 and then southwest towards Dallas while they were headed west towards Amarillo.  We will meet up with them next week, perhaps in Midland, Texas or on down the road in New Mexico.

Most of the rest of our drive was through rain but otherwise uneventful.  In spite of the weather the drive was very pretty.  I-30 west of Little Rock climbs through rolling hills with extensive woodlands on both sides of the highway.  We finally drove out from under the rain about 30 miles from Texarkana and finished the trip with bright sun and an ambient temperature of 74 degrees F.

It was easy enough getting off I-30 onto the southbound connector but a bit trickier getting over to make a right turn in the short distance we had.  But we did, and turned onto the road that runs in front of the Walmart and down to the far entrance, as planned.  I started my left turn into the parking lot road when a guy pulled up to make a left turn coming out of the parking lot.  I had tried to swing wide but he realized he needed to back up or risk damage to his truck, so he did.  I could not make the first left into the actual parking lot so I went down to the next entrance by the store.

I barely made a 180 degree turn into the first row, causing a women sitting in her car to just stare at us as I missed her by inches (apparently it did not occur to her to back up).  I had to straighten out before completing the turn to prevent scraping the driver’s side of the car on a huge boulder at the inside corner of the turn that I somehow did not see before I started the turn but caught sight of in my rearview mirror.  Considering that I just completed a drive through less than ideal conditions, which was probably more stressful than I acknowledged, this was not the way I wanted to end our driving for the day.  Like with airplanes, however, the takeoffs and landings are usually the trickiest parts.

We pulled into our selected parking spot at the back (east) end of the parking lot, in parallel with several tractor-trailer rigs, at 2:40 PM.  I went through our arrival procedure with one glitch; I could not raise or lower the front end of the coach using the Level Low system.  It worked fine yesterday so something had obviously changed.  I leveled the coach by adjusting the rear tires instead.  Once the coach was set I checked the house battery bank SOC.  It was 71% but the inverter/charger readout said the battery bank was at 25.0 VDC and the charger was delivering zero (0) Amps.  Since no loads were being powered I presumed the voltage was probably a good indication of the battery state.  A “12 volt” battery is fully charged at a resting (no load) voltage of 12.6 volts (2.1 volts per cell times six cells).  Double that for a “24 volt” battery bank and the full charge resting voltage is 25.2 volts, so our batteries being at 25.0 volts indicated they were probably near full charge.

I decided to wait and turn the generator on later when it was time to cook dinner and let it bring the batteries up to full charge.  At this point, however, I am suspicious of the reading I am getting from the Magnum BMK.  The data suggests that I do not have the ZENA power generating system tied in to the battery/charger/inverter system in such a way that the BMK can correctly account for the charge the ZENA is providing, but that seems unlikely.  Still, I will have to check when we get settled in Quartzsite (or back home in the spring) and/or see if there is a way to reset the 100% SOC level on the BMK.  We will be plugged in to a 50 Amp RV service tomorrow at Donn’s so I will see if the SOC rises to that level after being on shorepower for almost 48 hours.

Linda opened a few windows so the cats could have some fresh air.  We then walked over to the store for some exercise and fresh air ourselves.  I found a case for my Samsung Galaxy S III phone as a tab on my old holder has broken and it no longer holds the phone securely.  When we got back a pickup truck towing a 5th wheel trailer had pulled up next to us on the driver’s side.  It was parked such that our generator exhaust would blow in their entrance door.  I introduced myself to Gary and explained that we would be starting the GenSet in a little while.  He appreciated the heads up and elected to back up to where he was clear of our exhaust.

By the time I got back inside Linda was on the phone with Butch.  They were at a Wal-Mart in Checotah, Oklahoma just off I-40 about 60 miles west of the Arkansas border.  They also ran through rain the rest of the day and it was still raining there when he called.  The temporary air-pressure solution had continued to work well all day.

We ran on batteries/inverter until 5:30 PM and then started the generator so Linda could prepare dinner.  She needed to cook two baking potatoes in the microwave and sauté some onions, mushrooms, and broccoli using the induction cooker.  The microwave kept clicking and I noticed the current drop on that leg each time.  The other leg wasn’t drawing much current so I had her keep using the induction cooker and turned on the Aqua-Hot electric heating element.  That brought the current draw on each leg roughly into balance and the microwave behaved fine after that.  The charger was also drawing a few amps but not the much.

The microwave is wired through the inverter sub-panel.  With the generator running, each leg of the AC power is simply passed through the inverter to the sub-panel along with the neutral. I recall that the inverter relays are designed to carry 30 Amps on each leg, but we were only drawing about 20 Amps when the problem occurred so that should not be the source of the problem.  It appears that the genset may not tolerate 20 Amps on one leg and zero on the other, or perhaps a differential current draw of 20 Amps.  If that’s the case it is either an unfortunate design limitation or an indication that the generator is developing a problem.

In discussing this with Butch he said that gensets wired to produce 240VAC are usually set up to regulated that voltage but the 120VAC from L1 and L2 to Neutral can vary widely.  If the voltage on the microwave leg is dropping too low it will cause problems for the unit.  It is possible to rewire the genset to produce 120VAC and regulate that voltage, although it might require a new voltage regulator.  We would lose the use of our Gaggenau 2-burner cooktop but could live with that limitation.  Of more concern to me is the currents from L1 and L2 would now add in the Neutral wire rather than cancel, meaning the current in the Neutral conductor(s) could exceed their design specifications.

I got a TXT message from Chuck inquiring about our trip so I provided a few details.  I decided to check the bay under the driver’s seat to see if there was anything obviously wrong with the pneumatic solenoid valves that control the Level Low system.  There are red plastic fittings that screw into each solenoid and the fitting on the top one was unscrewed quite a bit.  The others were in tight so I screwed the top one back in.  I won’t know until tomorrow if that made a difference, but I decided to call Chuck and consult with him as I recalled him mentioning having had problems with these pilot valves on his H3-40.

Chuck did not think the plastic fittings were the problem but offered other salient advice about coils, ‘C’ clips, valves, and rubber ‘O’ rings.  If Donn will let us hang around for an extra day I will probably unhook the car and drive to the Prevost service facility near the Dallas Ft. Worth airport and pick up some new solenoid valves and perhaps a couple of Norgren valves and a windshield wiper motor.

We ended up with tractor-trailers pulling in and out around us well into the evening.  One in particular parked one spot over from us on the passenger side and let his engine idle for hours.  It felt like we were in a truck stop instead of a Wal-Mart parking lot, but given the price we had no basis to complain.  Still, if we wanted to stay at a truck stop we would have stayed at a truck stop.  Hopefully we can get a decent night’s sleep as I would like to be on the road at sunrise, which is 7:15 AM.

At 8 PM we went for a stroll around the store and the parking lot.  Wal-Mart parking lots are well lit as a rule and being 24/7/52 stores, there are always lots of people around making it a comfortable enough environment for an evening walk.  As we were getting ready to go to sleep I got a TXT message from Donn, with turn-by-turn directions for getting to his house and a couple of questions, which turned into a short TXT message conversation.  While I was texting with Donn our male cat, Jasper, came up by our pillows to look out the window and have a long back-stroking and chin-scratching session with Linda.  Traveling is stressful for the cats, especially at first, and they seek the comfort of our attention quite a bit (when they are not sleeping).  Squared away on tomorrow’s travel arrangements we drifted off to sleep to the gentle hum (rattle?) of large diesel engines.

Donn Barnes' place in Alvarado, Texas.  Yee Haw!

2014/12/06 (S) Alvarado, Texas

I was awake at 5 AM and got up shortly thereafter.  The house batteries were showing 58% SOC and 24.3 volts with no current draw.  I thought about not recharging the batteries and seeing how the ZENA system did on the drive today, but decided I did not want to risk depleting them below 50% SOC.  I turned on the generator and the Aqua-Hot electric heating element to balance the load and make hot water for our use this morning.  The charger went into Bulk Charging mode putting 88 Amps into the battery bank at 27.4 volts, so the batteries definitely needed recharging after running the coach for 8 hours.

We have and older, 22 cubic foot, residential (AC compressor) refrigerator that I presume accounts for most of the battery use overnight.  For each Ampere of current the inverter produces at 120 VAC it would draw 5 Amps from the “24 volt” batteries if it was 100% efficient, which it is not.  If I assume the SOC actually dropped from 88% last night at 9 PM (when I shut the generator off) to 58% at 5 AM this morning, the 30 percentage point drop would represent 120 A-Hrs of charge removed from the batteries (30% of 400) which equates to an average continuous draw of 15 Amps per hour at “24” volts.  Divide that by 6 (to account for inverter inefficiency) and you get 2.5 Amps per hour at 120 VAC, not that much, really.

It’s a bit more complicated than that, of course, as the refrigerator draws more current when it starts and has an electric heating element around the edge of the doors as well as an automatic defrost feature.  Those last two features are nice when connected to shorepower, but are not battery friendly, and I need to rig up a switch that allows me to turn these “features” off when we are dry-camping.  We also have an auxiliary air-compressor that supplies pressurized air to operate the toilet and other air-powered accessories.  It doesn’t run often but it draws a fair amount of current (at 120 VAC) when it does.  We also have small miscellaneous AC and DC loads that are on all the time, but collectively they add up.

By 6:30 AM the charger had shifted to Absorb Mode at 27.9 VDC and was putting 63 Amps into the batteries.  Between the charger, the refrigerator, and the electric heating element we were drawing 14 Amps on both legs.  I was hoping to be on the road this morning by 7:30 AM.  The batteries will not be fully charged by then, so this may be the first real test of the ZENA systems ability to maintain and recharge them while we drive.  My ultimate goal is to adjust the ZENA system so it can power the Magnum inverter/charger while we are driving at a level that is sufficient to run the refrigerator and fully, or almost fully, recharge the house battery bank.  That will apparently require some tweaking and additional testing which I am not going to do while parked at a Wal-Mart or other dry-camping location.

As we were getting ready to pull out I noted that the batteries were at 83% SOC and shut off the generator.  The drive from Texarkana to Alvarado was easy with dry conditions and sunny skies. Traffic was mostly light and we enjoyed the east-central Texas countryside.  Traffic got a lot denser as we neared Dallas but once we exited I-30 onto I-635 south it thinned out again.  It thickened again as we approached the exit for US-67 south and then thinned out and stayed that way for the rest of the trip to Alvarado.  We turned back north on I-35W and pulled in to Donn’s place a few miles north of Alvarado proper around 11:30.  I stopped in his driveway, exited the coach, was met by Donn, and we discussed where he wanted me to park.

The desired parking arrangement required us to unhook our car so we did that.  With Linda’s assistance I made a four-point turn to get the bus parked.  I pulled it up somewhat parallel to Donn’s Bluebird, backed up between the end of a building and a tree, swung forward into the driveway, and then backed around close to, and parallel to, the building.  I leveled the coach and this time the front adjustment of the Level Low system worked just fine.

Donn had a 50 Amp RV extension cord available to plug into conveniently located near our utilities bay.  By the time I got our coach plugged in it was noon.  I checked the meters for the house batteries and they indicated 76% SOC with the charger in Absorb Mode putting 56 Amps into the batteries.  For the 4.5 hours we were operating on batteries the expected drop would have been 13.5 to 16.2 percentage points at 3.0 to 3.6 percentage points per hour for a SOC of approximately 70 to 67, so 76 seemed OK, suggesting that the Zena system was doing something.

Linda got things squared away inside the coach and then we sat outside and chatted with Donn for a while.  He suggested we get lunch at Spiral, a vegan restaurant in the Ft. Worth medical district.  He drove since this is his home turf and he knows his way around.  Donn had quesadillas, Linda had a Philly cheesesteak, and I had a patty melt.  The food was very, very good.

After lunch Donn took us to Central Market.  The Market was not as refined as Whole Foods but had an amazing selection of fresh organic produce and specialty items, such as the tahini Linda needed to make her mock beef stroganoff tomorrow.  Our shopping done, Donn took us to meet his friend Jeanine, whose age (85) and health (not the best) prevent her from getting out much.  In spite of her issues we had a thoroughly delightful visit, after which we worked our way back to Donn’s place.

Linda checked on the cats and then drew three glasses of Shiner Bock draft beer.  Yes, Donn has beer on tap at all times; two taps, actually, but both had Shiner Bock.  We sat inside and had a long chat while enjoying our brews.  Neither of us had ever heard of bock style beer or the Shiner Company but it was good.  Donn was involved in raising mules, building wagons, and participated in a wagon trip around the state of Texas in 1986.  At 7 PM Donn started assembling a vegan pasta salad using quinoa pasta, bell pepper, and grape tomatoes.  Donn is an excellent cook but was very gracious about accommodating our vegan dietary preferences.

By 8:45 PM we were tired so we said “good night” and returned to our coach for the evening.  We read and wrote for a little while.  Butch called t let us know they had made it all the way to Amarillo in one day and were safely in the mobile home park where their friend lives.  The earliest they will be leaving is Tuesday morning, which may coincide with our travel plans.

2014/12/07 (N) A Day Of Rest

We slept in this morning, which meant I was awake at 6:30 AM, were up/dressed by 7:30, and enjoying our morning coffee (yeah) by 8:00.  It was in the mid-40s outside with dense fog, and 62 in the coach; perfect conditions for sleeping but a bit cool for sitting around.  The toilet would not flush and I suspected immediately that I had shut the wrong air valve last night.  In the excitement of our arrival yesterday, and finally being able to plug in to shore power for the first time since we left Indiana, I had forgotten to switch off the chassis batteries and close the unneeded air valves.  I did all of that using a flashlight right before going to bed and once again closed the wrong valve (I have made this mistake before).  Opening it this morning fixed the problem, so at least it was an easily corrected operator error and not something that was actually broken and needed to be repaired.

Donn, who is part Comanche, leant us a book by historian T. R. Fehrenback on their history and Linda started reading it this morning.  I scanned for WiFi networks with our WiFi Ranger (WFR) and found eight, including two that were “open.”  Open networks are not encrypted, so we prefer not to use them, but they may still require a password to gain access.  As a general rule we do not “borrow” open WiFi connections from unknown sources.  Our Verizon cellular signal here is a very strong 4G/LTE with five bars, but we prefer to use WiFi when available and save our limited cellular data for situations where it’s our only way to get online.  I suspected that one of the WiFi signals was Donn’s but could not tell which one it was.

We had oatmeal for breakfast, a nice treat on a cool morning.  Linda usually makes oatmeal from scratch these days, but she brought Quaker Instant Raisins, Dates, and Walnuts, which is my favorite.  It’s creamy without being mushy, and I just like the way it tastes.

We finally met up with Donn after breakfast and asked him about the available WiFi.  He was kind enough to give us the password to his wireless network.  He also gave us some Green Tomato Relish he had made and it was spectacular.  I mean, this guy can cook.  He put on some more coffee and we got back into a long morning discussion on a wide range of topics, so playing with our communications technology had to wait until later.

By 12:30 PM we were all getting hungry and Donn suggested the Mellow Mushroom in the TCU (Texas Christian University?) district of Ft. Worth.  We took the long way to get there so we could see the route we would follow when leaving the area and continuing our westward journey on I-20.  Our route took us down Camp Bowie Road, past the zoo, and a lovely adjacent neighborhood.  While not a vegan restaurant like Spiral, Mellow Mushroom had good vegan pizza options including Daiya non-dairy (non-animal) cheese.  We had a thin crust pizza with an olive oil and garlic base, with cheese, mushrooms, onions, and sun-dried tomatoes.  Yum.

After lunch we headed back to Alvarado but stopped first at Donn’s next door neighbor’s house so he could get his hair cut.  Back at his place we continued our conversation.  When it became clear that we were all a bit tired we went back to our coach to give Donn some personal space and downtime.  We agreed to meet back in his house between 7:00 and 7:30 PM for dinner.  Donn is slightly allergic to cats, so we did not visit or dine in our coach.

With the WiFi network key Donn had provided earlier I was able to connect our WFR to one of the available WiFi signals and upgrade its firmware.  I was then able to connect our Amped Wireless Access Point (AWAP) to the WFR, and connect our devices, including the NAS device, to the AWAP.  This was our standard setup this past winter in Florida.  We used this setup again at the Escapade in May and the GLAMARAMA in June but had not set it up yet on this trip.  The advantage of this setup is that the AWAP creates a secure wired/wireless network to which we connect all of our devices and can share data between them.  When we cannot connect the WFR to an external WiFi network we turn our Verizon MiFi on and connect the WFR to its WiFi signal instead while all of our devices remain connected to the AWAP.  It’s a pretty slick setup that has worked well for us and I was glad it was still working as we appeared to have issues with the WFR while in Twelve Mile, Indiana.

Linda checked online and most of the museums we thought about visiting tomorrow turned out to be closed on Mondays.  I was checking e-mail and had a announcement/confirmation for the FMCA National Education Committee worksession tomorrow at 3:00 PM CST.  If we do not leave until Wednesday morning we may try to go to a couple museums in Ft. worth on Tuesday while Donn is at work.

A little after 6 PM Linda started preparing her Seitan Mushroom Stroganoff.  This is a dish she has made and served at home to our non-vegan friends with great success.  Although Donn is a dedicated omnivore, he has other friends who are vegans and has been very thoughtful in the foods he has prepared for us and his selection of restaurants.

Linda used our Gaggenau electric cooktop to cook the dish.  She finished it at 7:25 PM and we took it over to the house.  We would normally have wine with this dish, but Donn has Shiner Bock beer on tap at the moment and, although I am not a big fan of beer, I found this one to be very much to my taste.  It also went well with the dish.  We talked for a while after dinner and retired to our coach at 10:45 PM as Donn had to be up early to drive into the office in Dallas.

2014/12/08 (M) Lucy, I’m Home!

Donn left for his office in Dallas long before we got up at 7:30 AM.  Granola with fresh bananas, grapefruit juice, and coffee made for a fine breakfast.  Donn left us access to the house so we could use the bathroom, which we greatly appreciated.  Yes, we have a bathroom onboard, but the less of our stored fresh water we use, and the less we put into our holding tanks, the longer we can go without stopping at a full-hookup RV park.  We left home on Sunday, November 30, so this is our 9th day on the road, and we are still above 2/3rds on our fresh-water tank, and probably below 1/3rd on each of our two holding tanks (black- and gray-water).  I say “probably” because the level sensors for those two tanks are not very accurate.

We left in our car at 9:30 AM and drove to the Fort Worth Prevost Car Inc. Parts and Service Center just south of the Dallas Fort Worth (DFW) airport in search of some spare parts for our Level Low system and lower windshield wipers.  The CatView program on my laptop showed a “641055 Manifold Valve / w/4 Solenoid” on drawing “H4-1640-00 Level-Low – Control Panel & Valves” but I knew I did not want this entire assembly.  Art, in the parts department, helped figure out the parts I was looking for, which turned out to be a “641928” for $41.28 and a “641929” for $35.60.  One is the solenoid coil and the other is the pneumatic valve, but I’m not sure which is which.

I was also looking for an “800304 Motor Wiper Assembly / 24V / Nidec” as shown on the “H4-2305-05 Lower Windshield Wiper – Installation” drawing.  CatView indicated that it had been superseded by “Kit #300506.”  That was correct and the cost was $200.03, but they saved me from spending the money as they did not have one in stock.  I was also thinking about getting a “641057 Valve, 5 Ways, 3 Positions” (Norgren K41EA00) and a “641056 Valve, 3 Ways, 2 Positions” (Norgren K910058).  They were $150.91 and $143.80 respectively so I did not even ask if they were in stock.  My diagram also showed a “562353 Diode / 1 Amp” but I decided not to ask about it at this time.  I can get most parts delivered in 2 – 3 days via UPS by ordering through their Elgin, Illinois center, but I am trying to stock a set of replacement parts that might be needed for a roadside repair.

Parts in hand we headed back south on TX-360 towards Six Flags to see if we could find the home stadiums of the Dallas Cowboys (AT&T Stadium) and Texas Rangers (Globe Life Park).  They were located just west of Six Flags and south of I-30, part of an amazing sports/entertainment complex euphemistically known as “Jerry World” after the owner of the Cowboys.

We got on I-30 westbound, exiting some 14 miles later at Montgomery Street, and followed the signs to the Fort Worth Cultural District.  We knew that most of the museums were closed today but we still wanted to see them from the outside.  Even if they had been open we did not have time today to go in as I had an FMCA National Education Committee meeting (telephone conference call) at 3 PM CST.  We did, however, have time to find Central Market again.

We walked up and down every isle and realized we had seen less than half of the store when we were here on Saturday.  Central Market may be the most amazing market we have ever been in.  As much as we like Whole Foods, it simply does not rise to the level of Central Market when it comes to fresh/organic items.  We picked up some additional fresh and packaged items, including a mix for white bean chili with jalapeños to make for dinner.

When we got back to our coach Linda started the chili.  We then took advantage of Donn’s hospitality to do a load of laundry only to discover his dryer was out of commission.  No problem; we just hung the laundry outside to dry in the late afternoon Texas sun and let it dry the old fashioned way.

Shortly before 3 PM CST I dialed in to the FMCA National Education Committee meeting and participated in the hour long work session.  There were good ideas put forward and it looks like I will have some specific things to do over the next several months.

While the chili cooked we both took a shower, again avoiding using our onboard water and waste tanks.  Donn is in the process of getting rid of lots of books and invited us to peruse them and take anything that looked interesting.  Linda found a half dozen titles, mostly paperback mysteries, that she will enjoy reading and then leaving in an RV park “library” someone down the road.  For never having met prior to noon on Saturday, Donn has treated us like old friends; a most considerate host.

Donn got home from work at 6:15 PM and I let him know that Linda had prepared the chili for dinner.  We waited 15 minutes for him to change clothes and tend to his dogs (Elvis and Lucy) and then brought the chili and some crackers to the house.  He provided the bowls, spoons, glasses, and draft beer.  I don’t think I will give up wine in favor of beer but the Shiner Bock that Donn keeps on draft was easy to drink and very tasty.  I detected a subtle hint of sweet citrus in the finish, but no one else did.

Butch called as I was finishing my first bowl of chili.  He reminded me that the SKP Dreamcatcher RV park is in Deming, NM just a few miles farther on past Las Cruces, NM and we discussed possibly meeting up there and staying the night.  He indicated that he had looked at the unloader valves on their main engine air-compressor and they may not be the problem.  Since the parts won’t make it to Amarillo until Wednesday or Thursday they are not going to stick around and planned to head out in the morning.  Linda got online to check distances and potential stopping points and found that it was 720 miles from here to Deming, NM and 313 miles to a convenient Wal-Mart in Midland, TX.  We let Donn know that we would probably leave in the morning and said our “farewells until next time” and thanked him for his generous hospitality.  If our future travels take us anywhere near Dallas Ft. Worth we will definitely stop and spend time with Donn.  Heck, we would travel here just to visit with him.

 

2014/12/01-04 (m-r) Westward Ho!

2014/12/01 (M) Back in Twelve Mile IN

As I indicated in yesterday’s post we are back in Twelve Mile, Indiana for a couple of days before heading on towards the southwest United States.  Butch and Fonda are scrambling to get ready and although there isn’t much we can do to help, we have made ourselves available.  If nothing else we can cheer them on.

We went to bed early last night, tired from our final departure preparations and 270 miles of travel yesterday, and slept in this morning.  Once we were up we had our usual granola with fresh fruit for breakfast and then walked over to Small Town Brew for coffee and conversation with owner Lisa Paul and whoever else happened in while we were there.

Well caffeinated, and pushing 9:30 AM, we checked in on Butch and Fonda.  There wasn’t anything we could help with so we both set up our computers and got online.  Linda paid bills while I updated the spreadsheet I use to track cross-purchase costs.  I hooked up their small Canon iP90 inkjet printer and printed out a copy for Butch and wrote him a check for the balance we owed them.  I showed Linda the MFJ-998 full legal limit antenna tuner that Butch wanted to sell and decided to buy it, resulting in a second check.  We plan to (eventually) use this in our base station, but it was a good enough deal that it was worth buying now and transporting to Arizona and back.  Buying it now also helped out our friends.  I logged in to RVillage and updated our location while Linda walked down to the Post Office two buildings to the west.  (Twelve Mile is a pretty small, compact town.)

Bill and Butch finished repairing Brittiny’s car this past week and she and Rock showed up mid-morning to pick it up.  We visited with them for a while and then Rock headed back while Brittiny visited with her mom.  While they were talking someone stopped across the street and off-loaded a camel.  They had three on the trailer but I’m not sure where they put the other two.  The three wise men, however, were nowhere to be seen.

Although the air temperature was in the upper 20’s it was sunny most of the day, which kept the front of the bus comfortable and well lit.  Given those conditions I decided to work on some projects in the center cockpit area.

First up was (finally) mounting the inclinometer, which turned out to be quite the little project.  I had to remove the mounting bracket from the case in order to attach it to my mounting blocks on the center windshield pillar.  That, in turn, required me to take the case apart and remove the mechanism so I could get to the ‘C’ clips that prevented the bracket retaining screws from coming all the way out of the body.  But I got it apart, mounted, and reassembled, minus the retaining clips.  Really, why would I put them back in?

Linda split the one remaining Tofurkey brand Italian sausage and served it on a couple of hotdog buns for lunch along with a couple of Clementine oranges.  A quick and simple but tasty lunch.

The inclinometer and the compass both have light bulbs in them and needed to be wired up to 12VDC accessory plugs.  The inclinometer already had a power cord but the compass did not, so I got some scrap wire from Butch and fashioned a 2-conductor power cable.  I only have four accessory outlets and three of them were already in use so I attached both power cables to a single plug using wire nuts.  I then dressed all of the wires to make for a neater looking installation that would keep them out of the way and prevent snagging and/or tripping problems.  All of this was a long-term temporary solution; I plan to eventually install a 12 VDC PowerPole distribution system for all of these accessories and hide the wiring to the extent possible or enclose it split cable loom.

I removed the four screws that hold the panel with the 12 VDC house system switches so I could get to the back side of them.  It took a while but I eventually puzzled out how the three air-conditioner switches were wired.  I removed the wire that feeds +12 VDC to the Rear A-C switch and checked for voltage at the loose end of the wire.  There wasn’t any, as expected, so I put a 2 Amp blade fuse in the 12 VDC distribution panel and checked again.  This time I had +13.2 VDC, so everything was good down to that point.  I removed the line and load wires from each switch in turn and checked to make sure the contacts opened and closed the way they should.  They did, so I checked each pin to ground to see if any of them were somehow shorted to ground.  They were not, so the problem was probably downstream from there.  I did not, however, specifically check the bulb circuit for each switch, so I don’t know if there’s a problem there or not.  The bulbs, however, get their power from the load side of each switch, so in the next paragraph the tests I did included the bulbs in parallel with whatever other loads existed.

I tested each load wire for continuity to ground and was surprised that they each appeared as a short.  I did this test with the DC- lead to ground and the DC+ lead to the wire.  When I reversed the leads each wire tested as open.  That suggested there was a diode, or something, acting as a one way current check valve.  I switched the VOM to measure resistance and rechecked each wire.  Where I had previously seen short circuits I saw 0 ohms; where I saw open circuits I now saw about 630 ohms.  Those readings might be a problem, but I don’t yet understand them well enough to know.

The bulbs are incandescent, so their resistance should measure the same in either direction.  If they are 0.6 W they would draw ~0.047 A and have a resistance of ~265 ohms (when illuminated), not the 630 ohms I saw with the red test lead grounded.  Regardless of the exact value, if a bulb was shorted I would see 0 ohms whichever way the test leads were connected.  With the black test lead to ground the 0 ohm readings were, therefore, presumably through the load wires not the bulbs.  If the relay coils were very low resistance (and protected by diodes) they would determine the meter reading in the forward direction, but I would have expected something more than a zero reading.  It seems very odd to me that all three of these loads tested as short circuits in one direction.

I had a weak Verizon 4G/LTE signal at the front of the bus so I tried calling Donn Barnes in Alvarado, Texas.  I got his voice mail and left a message indicating he could TXT message me back.  He did later and I replied that I would call him from Logansport a bit later.  Butch needed a 1/2″ x 1-1/2″ NPT male nipple so Linda and I drove to Logansport to buy one at Home Depot.  While we were there I called Donn and confirmed that he would be home this weekend and that we were still welcomed to visit and spend Saturday and Sunday at his place.  The timing looks like it will work out well as he has to work on Friday and Monday, so we will take our leave on Monday morning.

When we got back to the coach we had some pita chips with hummus while Linda prepared a green salad and started heating some lentil soup.  While we enjoyed the soup she reheated some pita bread and the leftover Koshary.  A small glass of Moscato went nicely with the meal.  After dinner we went in the house to visit with Butch and Fonda for a while and transfer some PDF files onto a flash drive for Butch.  We returned to our coach for the evening at 9 PM.  It was certainly an easier day for us than for Butch and Fonda, but we were tired nonetheless.

We were sitting quietly, reading and writing, when things suddenly got exciting.  Juniper made a sudden movement near the food bowls and I immediately glanced in her direction to see that she had caught a mouse.  We knew at least one was probably still living in the bus because yesterday we found a partially shredded blue paper shop towel in the tray where we store the shore power cords, along with two nuts that had been chewed open.

Juniper is a very skillful huntress but I was surprised that the mouse attempted to get to the cats’ food bowls, which are not in a really safe place for a mouse, with two cats on board.  Juniper is very protective of her catches, so she headed off towards the bedroom, trying to find someplace where we could not try to take it away from her.  We wanted to get it from her and remove it from the coach but our main concern was that she not kill it and try to eat it.

I got a container to try to capture it and Linda managed to get hold of the scruff of Juniper’s neck which caused her to drop the mouse.  It immediately ran further under the bed, a direction from which there did not appear to be an escape path, but we could find no sign of it save a few stool pellets.  I would have needed a much deeper container, like the trash can, to capture it.  Our best guess is that it disappeared into the OTR HVAC duct on Linda’s side of the bed.  Once in there it could travel the length of the bus with impunity, including moving from side to side and between the house and the bay’s.  With any luck it took the hint and moved outside.

Juniper took up her post by the rear corner of the dinette, where she originally caught the mouse, to wait for its reappearance.  A black cat sitting quietly on black tile at night is a pretty effective camouflage.  The problem for the mouse is that it needs to eat and even in its natural (outdoor) environment constantly takes risks to obtain food.

2014/12/02 (T) Tire(d) Pressures

Some nights we sleep better than others.  Last night was not one of our better nights.  The cats were still wound up because of the mouse and I suspect we were anticipating its return as well.  Because neither of us slept well, we slept in this morning.  By the time we were up and dressed it was 8:30 AM.  Linda was pretty sure she had left her gloves and knit hat at the coffee shop yesterday so we decided to go have coffee at Small Town Brew before we ate breakfast.

Linda’s things were there waiting for her to claim them.  We had a nice long chat with proprietor Lisa Paul and invited her to stop over after she closed the coffee shop for the day and get an inside tour of both buses.  We also inquired as to whether she had any post cards of Twelve Mile.  She did not but thought it would be nice to have a few available.  She has a friend, Derinda, who is an artist and thought she would ask her to make a few.  We were interested in one we could mail to our grand-daughter, Madeline, who will be two years old in less than three weeks.

Breakfast was raisin toast and grapefruit, simple but yummy.  We were both dressed to work and went in search of Butch and Fonda to see if we could be of any assistance.  Linda took her computer in the house to transfer some PDF manuals to Butch and then take care of some bakery-related issues.  I used Butch’s MFJ-269 SWR Analyzer to check the VSWR on his 2 meter ham antenna and his (11 meter) CB antenna.  Both antennas are glass mount.  The 2m ham antenna was tuned fairly well, showing a VSWR of 2.1 at the low end of the band (144.000 MHz) and 1.8 across most of the band (up 148.000 MHz).  That is certainly a usable range.

The CB antenna did not test nearly as well.  The CB band is channelized, with channel 1 just below 27.000 MHz and channel 40 just above 27.400 MHz.  At 27.0 MHz the VSWR was greater than 6.0.  It declined steadily as I went up in frequency but was only down to 2.9 by the time I got to Channel 40.  A reading greater than 2.0 (a ratio greater than 2:1) becomes problematic for a transmitter and readings greater than 3.0 are generally unusable.  Both of Butch’s antennas are tunable but we did not take the time to adjust them today.  Butch is taking the analyzer so we can work on the antennas while we are in Quartzsite.

Their bus is parked in between our bus and their house as a consequence of which our WiFi Ranger is not able to pick up their WiFi network signal which is already weak outside the house.  I am having a problem with the unit that has me concerned, but I won’t be able to sort it out until I can get it connected to a working Internet connection.  The problem is that the WFR finds their network and tries to connect to it, requests an IP address, and while it is waiting for a response disconnects from my iPad, which serves as its control panel.  This annoying at best since the WFR and the iPad are only 10 feet apart.

We had lunch at 1:30 PM.  Linda heated up a couple of Thai Kitchen brand hot and sour rice noodle soup bowls.  It had been cold, damp, and dreary all day and we were both feeling a bit chilled so the soup was very soothing in addition to being very tasty.  By 2 PM it was obvious we were not going to get the mid-to-upper 30’s temperatures that had been forecast and there was no advantage to waiting any longer to check/set the tire pressures.  I bundled up, put on my mechanic’s gloves, and set about the business at hand.

Butch turned the auto shop compressor on and I pulled the air hose out and connected it to our hose.  I removed the Pressure Pro sensors from all 12 tires and then worked my way around both vehicles in the same order.  When the sensors have been off for a minimum of one minute putting them back on resets the baseline pressure, which determines the pressures at which you get over- and under-pressure warnings.  I set the bus tires as follows:  front tires to 115 PSI, drive tires to 95 PSI, and tag tires to 85 PSI.  I set the car front tires to 32 PSI and the rear tires to 34 PSI.  I noted that the ambient temperature was 30 degrees F.  I then plugged in the Pressure Pro receiver and repeater and checked the pressures they were reporting.  The four car tire readings were essentially identical to the known pressures in the tires, but the sensors on the eight bus tires all registered low, in one case by 6 lbs.  As I indicated in a previous post I think the batteries are just about drained and are giving tire(d) pressure readings.  I know that I am tired of the discrepancies as I count on these readings to tell me it’s OK to drive or I need to add air to certain tires.

Bill and Bell showed up in his custom car hauler while I was working on the tires.  Bill and Butch worked on some stuff and Bell helped Fonda load food and sundries onto the bus.  Lisa Paul showed up for a brief visit and tour of both buses.  See also brought a postcard that her friend Derinda made.  It featured the building that houses Lisa’s Small Town Brew coffee shop.  Linda is going to post it to Madeline in the morning so it has a Twelve Mile, Indiana postmark.  It will be the first of what we hope are many such postcards from far away exotic places.  Being almost two years old we hope these mementos will provide a tangible connection to us while we are traveling.  I know her parents will use them as learning opportunities.

Linda and I took showers in the house to minimize the use of our stored water and waste tank capacity.  The six of us then drove down to The Old Mill restaurant just west of town for an earlier than normal dinner.  The restaurant also allowed us to use their dumpster to dispose of our accumulated household trash.  That was nice because Butch and Fonda had already suspended their dumpster service for the winter.

When we got back from dinner we got online and checked the weather forecast and road conditions along our planned route.  Bill had recently driven I-70 west of Indianapolis and strongly advised us to avoid going that way.  Our check of the INDOT website confirmed that we were well advised to avoid Indianapolis altogether.  We settled on SR-16 east to US-31 south to US-24 west to I-57 in Illinois.  From there we will take I-57 south to Mt. Vernon, Illinois where we will overnight at Wally World (Walmart).

Bill and Bell said they would be back in the morning to see us off (“watch this thing launch” is how Bill put it) and took their leave.  We hung out a while longer trying to be useful but mostly providing moral support and comic relief until it was time to winterize the plumbing.  Butch hooked up a line from his big shop air compressor, ran it through a pressure regulator, and attached it to the main plumbing line at the surge tank and pump.  Just like an RV he used air pressure to drain both water heaters and then had us open each fixture in turn and let the air blow the water out and down the drain.  We then filled the traps and toilet tanks with potable RV antifreeze.  The reason for using potable antifreeze is that it will eventually end up in the septic tank and drain field.

We finally retired to our coach leaving them to finish up some last minute things before retiring to their coach for the night.  We had some very tasty red grapes for dessert (and a couple of cookies) while we studied maps for our next few days of travel.  We had not really looked at them carefully before now and were surprised to find that we will not be in either Kentucky or Tennessee.  We had presumed that we would be, but I-57 runs into the extreme southwest corner of Illinois and then crosses the Mississippi River into Missouri, ending at I-55 in Sikeston.  From there we will continue south into Arkansas on I-55, which stays on the west side of the Mississippi river, until we intersect I-40 west of Memphis and head west towards Little Rock.  Thus we will never enter Kentucky or Tennessee and we will not drive through Memphis; at least not on purpose.

Fonda has to run to Logansport first thing tomorrow and while she is gone we will prep our bus for travel, hitch up our car, and give Butch whatever assistance we can.  We plan to be on the road by 10 AM and safely parked at the Walmart in Mt. Vernon, Illinois well before dark.

2014/12/03 (W) Finally On Our Way

We were up around 7:45 this morning anticipating a 9 AM departure even though we knew that was unlikely.  I turned on the Aqua-Hot engine pre-heat pump to start warming the engine.  There was a dusting of snow on the ground and on our car; a sure sign that our departure had been delayed long enough.

Bill and Bell arrived a little after 8 AM so we invited them into the coach and chatted for over an hour while Butch and Fonda got their morning organized.  Fonda left for her run to Logansport at 9:15 AM followed by Bill and Bell at 9:25 AM when they decided they needed to go to Logansport to get breakfast.  Fonda returned at 9:50 AM and we started making our final departure preparations.  We had hoped to leave by 10 AM but suspected that was optimistic.  It’s Butch and Fonda’s first extended use of their converted coach and they have had a lot to do to get ready to leave.

We straightened up the interior for travel as soon as Bill and Bell left so all that remained for us to do was unhook the shorepower cord and store it, start up the main engine, move the bus across the street, and hookup the car for towing.  We can do all of that in 15-20 minutes if absolutely necessary, especially in warmer weather, but it typically takes a half hour.  We do not like to rush this process; it’s important that we do it correctly each and every time.  It is also a commonly understood etiquette among RVers that you do not try to chit-chat with, or otherwise disturb, fellow road warriors while they are hitching something up.

Butch & Fonda’s MC-9 getting ready to depart Twelve Mile, IN.

We were idling and ready to go by 10:25 AM but Butch had to make some final adjustments to his toad towing/braking setup.  Bill and Bell were back in time for Bill to help and Bell to take pictures and give us a good send off.  We pulled out a little after 11 AM and headed east on SR-16 with Butch in the lead but only got to the edge of town before Butch pulled off the road.  We pulled off behind him and Bill pulled off the on the other side.  We had noticed that their bus was smoking but they realized something was wrong before we could even call them on our 2m ham radio.  It wasn’t the engine; the brakes on the toad were partially engaged and he could feel the drag.  He readjusted it and we were on our way again, this time for good.

The trip to Mt. Vernon, Illinois was an easy and uneventful run.  From SR-16 we turned south on US-31 and picked up US-24 westbound.  We took this same route in June 2013 when we left Twelve Mile headed to the state of Wyoming so we knew it was a good route for us.  We had to slow down going through small towns, but that gave us a chance to catch a glimpse of these quaint little places.  A couple of larger towns had stop lights, but mostly we were able to keep rolling.

We stopped at a Pilot Truck Stop just west of I-65 for a quick walk-around and so Fonda could take the dogs out.  We continued west on US-24 into Illinois and eventually got to I-57 where we headed south.  We saw occasional construction signs but very little construction and did not incur any delays.  Butch lead most of the day and we just followed along with generally light traffic.

We stopped at the rest area just north of I-70 and took a stretch break, after which we took the lead.  A few miles later we got to the construction on the short stretch where I-57 and I-70 run together.  We had to drive 45 MPH but rolled right through.  After the construction zone we took the center lane knowing that I-57 would split to the left from I-70 and continue southbound.  Slow traffic is often worse than fast traffic as the cars end up bumper-to-bumper leaving no space for larger vehicles to change lanes.

Following the directions on our GPS we took exit 95 for Mt. Vernon, Illinois, drove a quarter mile, and turned left onto a road that ran down the west side of the Wal-Mart property.  Linda had called ahead and been told it was OK for us to spend the night in their parking lot.  The first two access drives, however, had crossbars at 12 feet so we could not turn in. The third driveway was for delivery trucks so we turned in there and headed back towards the north end of the lot by Ryan’s as Linda had been instructed on the phone.  There were signs posted prohibiting semi-truck parking so we parked temporarily while Linda went in to check on the situation.

A women at customer service confirmed that we could spend the night and asked that we stay near the periphery of their parking lot away from the main doors.  No problem.  The lot we had pulled into was not the Wal-Mart lot and was a little tight but were able to extricate both coaches without unhooking our toads and moved them to the northeast corner of the adjacent/connected Wal-Mart parking lot.  I leveled up as best I could, shut the engine off, and then closed the various air valves and switched the chassis batteries off.

The house batteries were at an 89% state of charge (SOC) when we arrived.  We locked the bus and went for a walk around the east end of the building to scout out an exit route.  We stopped in the store and bought a bag of Fritos and some popcorn oil.  When we got back to the coach I started the diesel genset and turned on two of the electric toekick heaters while Linda used the induction cooker to prepare vegan burgers for dinner.

After we had eaten Linda and I sent TXT messages to several people.  We then went over to visit briefly with Butch and Fonda and look at maps for tomorrow’s leg of the trip.  When we returned to our coach we noticed that the generator had stopped running.  Not good.  I was able to restart it but each time it shut down, so I got Butch to come look at it.

There’s a solenoid that holds a fuel valve open and we thought that might be the problem, but it wasn’t.  We checked the level of the oil but it was OK.  I started it again and Butch noticed that the squirrel cage fresh air blower was not turning so I shut the engine off.  Linda had been watching the gauges inside and said the water temperature was very high (off the end of the scale).  Butch checked the blower to make sure it wasn’t stuck. I traced the wiring back to a panel with a couple of circuit breakers and one of them was popped.  I reset it and restarted the engine and the blower came on.  Linda reported that the water temperature immediately dropped.  We suspected, but did not confirm, that the same breaker controlled the power to the large squirrel cage blower for the radiator, which is located in the inverter bay on the other side of the bus.  I let it run for another hour and brought the house batteries up to 95%.  It ran fine with normal water temperature and oil pressure so I think we found the problem and fixed it.

Linda read while I changed most of the clocks to Central Standard Time.  I turned off the electric heating element in the Aqua-Hot to unload the GenSet and then shut it down for the night.  I dialed the three Aqua-Hot thermostats back to 15 degrees C (59 degrees F) and turned on the Diesel burner.  It is only supposed to get down to 32 degrees Fahrenheit overnight but Linda put an extra blanket on the bed since we will not be using the electric heating pads as they would draw too much energy from the batteries.

It was a long day but largely uneventful except for the beginning and the end.  But all’s well that ends well, and this day did.

2014/12/04 (R) Roadside Repair

I was awake at 4:30 AM and got up to check on the SOC of the house batteries and turn on the Aqua-Hot engine pre-heat pump.  The batteries were at 68 SOC.  They were at 95% when I shut the generator off around 9 PM last night, so they had dropped 27% percentage points in 7.5 hours, a rate of 3.6 percentage points per hour or 10 percentage points every 2 hours and 45 minutes.  We did not go out of our way to minimize loads, leaving some night lights on (DC), the Aqua-Hot (DC), and the main inverter loads (refrigerator, auxiliary air-compressor, microwave clock, outlets with chargers, etc.). At that rate it would take just under 14 hours for the batteries to drop to a 50% SOC, starting from 100%.  I was satisfied with the performance of the system and went back to bed.

It started to rain off and on around 5:30 AM, the first sign of a wet day.  I got up to stay at 7:15 AM and got dressed.  I checked the SOC of the house batteries and it was 58%, so it had dropped another 10% in 2 and 3/4 hours, consistent with the 4:30 AM data.  I started the generator to provide power for hot water, lights, and additional engine pre-heating.  It would also start to bring the SOC of the house batteries back up before we started driving for the day, although the Zena power generating system on the main engine should be capable of recharging them in a couple of hours while we are driving.

Since we were not leaving until at least 9 AM we decided to have a light breakfast of raisin bread and grapefruit.  After breakfast I powered up our Verizon Mi-Fi device, got my laptop connected to it, e-mailed yesterday’s blog post to myself (from my iPad), and then checked my e-mail (on my computer).

We had the coach straightened up and ready to go well ahead of our departure.  Around 8:45 Butch indicated that they would be ready to go in 15 minutes.  That was all the time I needed to get the car ready to tow, switch the coach batteries on, open the various air valves, shut off the Aqua-Hot pre-heat loop, and start the main engine.  With the main engine running I turned off all of the loads on the generator, let it run unloaded for a few minutes to cool down, and then shut it off.

We pulled out at 9 AM and worked our way around behind the store and back out the unblocked entrance we came in yesterday.  Instead of turning on Broadway to go back to the Interstate we crossed over and pulled into the Pilot Truck Stop so Butch could top off their fuel tank.  We did not need fuel yet but I pulled in right behind him so we were positioned to pull out together.

We were back on I-57 headed south by 9:25 AM with Butch in the lead.  We ran at 60 MPH through light rain and fog with overcast skies all the way to the end of I-57 at I-55 near Sikeston, Missouri, where we continued south towards Memphis, Tennessee.  We eventually crossed into Arkansas and out of the rain, although the cloudy skies continued.  About 25 miles north of the junction with I-40 Butch called on the radio to let us know that he needed to get off the road at the first safe place I could find.  His air pressure had dropped to 60 PSI and was not building.  A couple of miles later I pulled off onto the shoulder of an entrance ramp and he pulled off behind me.  The brakes and suspension most highway buses are air-powered.  Without proper air-pressure the bus cannot be driven.

The pressure in the system was holding which indicated a supply issue rather than a leak.  The usual suspect in this situation is the “governor” (or less likely the unloader valves) on the main engine air-compressor.  Butch had a spare governor in his parts kit but we were not in an ideal spot for changing it.  He decided instead to hook up his portable air-compressor to his air system auxiliary fill connector.  He put the portable air-compressor in the bedroom at the rear of the bus and had Fonda run the air hose out the passenger side window were I took it and zip tied it to the side radiator grill.  Butch then ran it through a small access door by the passenger side rear lights and connected it to the fill valve.  The portable air-compressor is an AC powered device, so Butch had to start their generator to power it.  It gradually built the pressure to 100 PSI.  The pressure was holding so Butch dial it up to 110 PSI.  He left the portable air-compressor on for the rest of the trip and allowed us to get back on the road, making this a very clever emergency roadside fix.

After a 20 minute delay we pulled back onto I-55 and finished the run to I-40 with heavier traffic.  We exited onto westbound I-40 in West Memphis, Arkansas and completed the 38 miles to Forest City, Arkansas without difficulty.  We negotiated a tight turn onto the street where the Wal-Mart was located but had an easy time getting in at the far west entrance.  From there we pulled up parallel to a north-south curb that ran the length of the west edge of the parking lot.  We leveled up the coach (using the air springs), shut down the engine, and went through our usual dry-camping arrival routine.

As soon as we were set up Butch was back looking at his main engine air-compressor and then on the phone with Luke at U. S. Coach in New Jersey.  He decided to change the governor as it couldn’t do any harm.  I helped him (as best I could) but once the new governor was installed the compressor still would not build air pressure.  The unloader valves were the next most likely (easiest to fix) culprits, but neither of us had the parts.  There was an O’Reilly’s Auto Store across the main road from the Wal-Mart so we walked over there.  They did not stock them either, but at least we got some exercise.

The house batteries were at 78% SOC when we arrived which disappointed me as I expected them to be at least at 88% like they were yesterday at the end of our drive.  We were on the inverter from the time we started up at 9 AM until I turned the generator on at about 3:30 PM.  At our normal rate of 3.6 percentage points per hour we would have been at ~72% SOC without any charging from the ZENA system, so 78% did not seem very good to me.  It appears that I am going to have to adjust the charge voltage up somewhat on the ZENA power generating system as it should be supply enough current to run any AC loads while traveling (mostly the refrigerator) and fully recharge the house batteries.  I let the generator run through dinner until bedtime.  It brought the SOC back up to 91% with the charger in float mode supplying 10 Amps of current at 26.3 VDC.  Once the charger is in float mode it can take a surprisingly long time to finishing bringing the batteries to full charge.

Some weeks back Butch bought a grandfathered Verizon unlimited data plan on Ebay using the Assumption Of Liability (AOL) process.  He also picked up a used phone and a used Jetpack MiFi device.  Both devices can use the SIM card, but he had not had a chance to connect the MiFi through to the Internet.  We removed the card from the phone, installed it in the MiFi and powered it up.  It found a strong Verizon 4G/LTE signal right away.  The menu gave us the password and we were able to connect his laptop computer and my iPad.  He started searching the web while I downloaded e-mails.

Linda and Fonda had walked to the store to buy a few things.  When they got back we chatted for a bit and then went back to our coach.  Linda made popcorn for me (she wasn’t hungry) and we relaxed for a while before going to bed.

 

2014/10/16-22 More Bus Work

2014/10/16 (R) More Wiring

Butch had to go to Logansport this morning for parts and groceries.  I stayed behind to continue working on the AC wiring for their bus conversion; after breakfast, of course.

I mounted two 6-position AC main lug panels, one above the other, to the right of the 20-position panel we installed yesterday for the inverter circuits.  The panels I installed today were for AC circuits that only run on shore power or the generator, not the inverter.  The reason for two panels was: A) Butch already had them, and B) they were narrower than the larger panels and would fit in the available space on the right rear wall of the closet.

I had tied the main shore/generator power line to the inverter AC input line last night so the refrigerator, which is wired through the inverter panel, would have power overnight.  I left those tied together for most of the day so the lights would work.  I pulled all of the existing circuits that we disconnected yesterday into the boxes, dressed the wires, and connected/mounted the circuit breakers.  By the time I finished Butch had returned from his morning errands.  He connected the shoreline and I checked to see that we had 240 VAC between L1 and L2 and 120 VAC from each line to the neutral conductor.  He then disconnected the shoreline and made sure the generator was off.  Using the inverter to power a work light, I pulled the main power cable into the lower box and secured it.  I then pulled the cable that feeds AC power to the inverter into the lower box and connected it to a 30 Amp breaker.

I plugged the shoreline back in but got a low voltage with no current on L2 and an Error Code 6 on the Progressive Industries EMS remote monitor display.  Butch checked the plug and I just did not have it fully inserted into the outlet.  Once he fixed that we got the correct voltages and no errors.  We checked each circuit and everything checked out perfectly.

(Note: The shoreline is wired for “50 A” RV service, which is 240 VAC service from L1 to L2 but with an active neutral that provides two 50 A, 120 VAC power feeds with L1 and L2 180 degrees out of phase.  As a result the currents in the neutral wire from L1 and L2 cancel rather than add.  Butch has his generator wired for 120 VAC output and has L1 and L2 tied together on the generator side of the transfer switch.  This makes the full 100 A output of the generator available to be shared between L1 and L2 in any proportion.  Although this system can supply a full 50 A of current on both L1 and L2 at the same time, it could also supply 70 A or one and 30 A on the other unless this is prevented by circuit breakers.  Also, regardless of the distribution of current between L1 and L2 the currents will add in the neutral as much as 100 A of current.  Although sensible load management would prevent this from ever happening it is entirely possible to draw 30 or 35 A on each leg and end up with 60 – 70 A in the neutral.  Thus, when designing your house AC electrical system this way, provision should be made for a neutral conductor that is sufficient to carry this amount of current.  The advantage to doing your system this way is that the voltage regulation will be better under load than with a 240 VAC generator powering imbalanced 120 VAC loads on both legs as the 240 VAC configuration regulates the voltage between L1 and L2 but the voltage from L1 to N and L2 to N can be off substantially.)

Butch needed another non-inverter circuit for the front of the bus so we pulled a 10-2+g Romex cable from the electrical closet along the driver’s side wall/ceiling area and down into the cabinet at the front end of the kitchen counter. He and Fonda spent a bit of time cutting openings in the end of the cabinet for a two-gang outlet box and a single-gang outlet box.  The two-gang box was for a pair of duplex outlets fed from the inverter panel and the wires were already run.  The single-gang was for the new circuit we just pulled.  When they were done I disconnected the shoreline so I could safely tie the new circuit into the lower panel.  I then installed the cover plates on all three boxes and plugged the shoreline back in.  We had the breaker turned off for the new circuit while I wired the outlet.  I then energized it and it tested OK.

I repositioned a 12 VDC fused distribution box above the inverter panel and mounted it.  I then moved a terminal strip for their solar panel wiring to a slightly different location to open up a space for Butch to drill a hole.  At that point we were done working for the day.  I changed into my non-work blue jeans and relaxed for an hour before dinner.  During that time Butch called Jaral Beatty, a cabinet maker in Logansport and personal friend of Butch’s, and put me on the phone with him to see if he could come to Twelve Mile and finalize plans for a custom desk and printer cabinet for the bus.  The weather forecast for tomorrow is for mild, mainly sunny, conditions and Jaral said he could come out mid-afternoon.

Butch and Fonda’s younger daughter, Brittani, and her husband, Sterling (Rock), were expected for dinner at 7:00 PM so I fixed a salad and heated some Amy’s chili for my dinner.  Dinner was jovial and the first time I have eaten with Butch and Fonda at home on this latest round of working visits.  Butch called Joe Leibherr and put me on the phone with him.  Joe and Connie own the lot in Quartzite where we plan to spend part of the winter and I had a few questions for him.  (Dale and Sherry Leibherr bought most of Butch and Fonda’s business assets.  Dale is Joe and Connie’s son.)  I had a nice long chat with Joe and was satisfied that it will be an OK place to spend part of the winter.  Besides the full hookup 50A sites there is a laundry on site and Wi-Fi.  Verizon cellular service is also apparently very good.  Joe filled me in on some of things to do in town and suggested we bring our passports and visit Los Algodones, Mexico while we are in the area.  Brittiny and Rock stayed until 11:30 PM so it was a nice, long visit.  We were all really tired by the time they left and immediately turned in for the night.

2014/10/17 (F) VDO Air Power

After Brittani and Sterling (Rock) left last night I retired to the guest bedroom immediately but was up for a couple of hours responding to e-mails and writing my daily blog entry.  I do not shut my computer down every night but I do shut it down occasionally, especially if there are updates available.  Last night there were 28 updates.  I was not up at the crack of dawn today, which was a shame as it was the nicest weather day we’ve had for the week just past and looks to be the nicest of the week ahead.  Butch was up late last night as well, so we were both dragging a bit this morning.

Following breakfast I readied the coach for travel, securing loose objects inside and checking that all of the bays were shut tight and locked.  I switched on the chassis batteries and air valves, unplugged the shorepower cord, and went for a short test drive to calibrate our new VDO electronic speedometer.  Butch mentioned that there was a funeral home on the northwest corner of SR-16 and US-31 where he had easily turned their bus around in the past.  That turned out to be just what I needed for my test run as it kept me from having to go south on US-31 in order to make a U-turn to get headed back to Twelve Mile.

I had driven the coach last Sunday from Elkhart to Twelve Mile with the new speedometer set to its default pulses per mile and it indicated less than 1/8th of the actual speed as shown on our Rand-McNally 7710 RVND GPS.  When I got to Twelve Mile I calculated the pulses per mile I thought would be close to correct and programmed that number into the instrument.  On the first leg of my test drive this morning the indicated speed was still about 1/8th of actual.  Either my programming did not “stick” or I based my calculation on a grossly inaccurate assumption.

I pulled into the far entrance to the funeral home parking lot and made a broad turn to get lined up with the other entrance.  I switched off the ignition, held down the button on the face of the VDO, turned the ignition back on, and started the engine.  The speedometer cycled through its three calibration modes and I stopped it on ADJUST and then selected UP as the direction the needle needed to move.  The adjustment was a little tricky, especially while driving, but I figured out how to switch it between up and down.  I got it adjusted to my satisfaction before getting back to Twelve Mile and after not adjusting it for a minute or so it reset and reverted to its standard speedometer/odometer display, only this time showing the correct speed and recording the correct mileage.

When I got back to Butch and Fonda’s house I pulled the bus around, blocking the street temporarily, and backed it in next to theirs.  Fonda helped spot me for the final few feet.  Instead of shutting the engine off I let it idle while I got my four chassis stands out of the warehouse and positioned them at the four corners of the bus.  I put the engine in high idle and raised the body as high above the axles as it would go.  I slid the stands into place under four frame members, dropped the idle to low, and gently lowered the bus until it was resting firmly on the stands.  With the bus sitting on the stands it will now be safe to work underneath it when we get around to those projects.

The next project was to replace the air filter / water separator for our auxiliary air system.  Butch did most of the work on this project.  He disconnected two air lines from the existing filter assembly, which includes a pressure regulator and a Schrader valve, and then unscrewed the mounting bracket from the rear wall of the bay under the driver’s seat where a lot of the auxiliary air system is housed.

With the old unit out of the bus he was able to work in his shop to remove the inlet and outlet fittings and clean them up on a wire wheel before reusing them.  He installed the old fittings in the new housing using pipe thread compound and matched the alignment of the old unit so the air lines would fit back on to them.  The two machine screws that were used to mount the old unit’s mounting bracket to the wall were too big for the slots in the new unit’s mounting bracket so Butch used his Bridgeport vertical mill to slightly enlarge the upper slots.

With the shop work done I took everything back out to the bus and installed it, which consisted of attaching the two air lines (with compression fittings), attaching the mounting bracket to the housing, attaching the mounting bracket to the rear wall of the compartment, and then tightening the two air line nuts.  Butch checked my work and snugged the air line nuts another partial turn.

I turned on the auxiliary air compressor but it seemed to take a long time to start to build air pressure and Butch heard and felt a leak at the unloader valve coming out of the auxiliary air compressor.  I shut of the aux compressor and he hooked up his portable air compressor to the air hose fitting in the passenger side engine bay which brought the pressure up in the auxiliary system very nicely.  We turned his compressor off, turned the aux compressor back on, and bled enough air off to cause the aux compressor to run.  It finished bringing the pressure up to the cutout value without difficulty.  I sprayed all of the fittings with Simple Green and did not detect any leaks.  We had noticed earlier that the lower half of the filter housing, which locks and unlocks in only 1/8th of a turn, had a loose fit.  Once the system was pressurized, however, it tightened up.

The old unit had to be replaced because it was no longer made and the replaceable filters were no longer available.  Once we had it out of the coach and disassembled I was surprised by how badly deteriorated it was internally.  Aluminum, by definition, does not “rust” but it certainly can and does corrode (oxidize).

Butch and Fonda spent part of the day building and installing a slide out tray for one of the passenger side bays.  It will hold his tool box on top and have room for miscellaneous storage underneath.

I got the Zena power generating module wiring diagrams for Butch to study while I ate lunch.  We were just getting ready to start working on this when Jaral showed up.  He and Butch and Fonda talked for quite a while about personal stuff while I started probing around in the driver side rear electrical bay for a place to tap into an ignition switched source of 24VDC power.  I located a relay that looked like it would do the trick (R53).  I broke off working on this to spend time with Jaral, who rode his scooter from Logansport to discuss some cabinetry project.

Jaral looked at Butch’s projects first as they are immediate.  He then looked at what we want to do with the front part of our coach.  We need to have a desk and a printer cabinet built out of walnut to match the woodwork that is already in the bus and Jaral is our cabinetmaker of choice.  It sounds simple enough, but the reality is more complex.  After talking it through with him (again) and taking some measurements we agreed that I need to make very careful dimensioned drawings of exactly what we need.  I may try to do that over the winter but worst case is that it will have to wait until next spring and probably after we have removed the current furniture.

Butch and I worked on the Zena wiring for a little while after Jaral left.  We determined that the two blue wires in the electrical bay ran to the Zena control modules in the engine bay and to the fan terminals on the Zena rectifier assembly in the house electrical bay.  He had a tandem spade lug adapter that we used to tap into the power to the coil of relay 53.  With the coach batteries on but the ignition off we did not have power to the fans on the rectifier assembly or the control modules in the engine bay but with the ignition on we did.  That was a small but important success.

The weather had turned cloudy, windy, and chilly as the afternoon progressed.  We spent a little while studying my house electrical bay and discussing how I might get the large battery charging cables from the ceiling-mounted rectifier to a Class T fuse and then to the batteries.  I decided that was a problem I was not going to solve in the remaining hour of daylight and called it a day.  By then it was 6 PM so I went to my coach to have dinner which consisted of a salad, tofu hot dog, apple, and a glass of Franzia Moscato.  I retired to the guest bedroom around 9 PM, worked on my computer and iPad until about 10:30, and then turned off the lights.

2014/10/18 (S) Cold Wet & Windy

Even though I went to sleep at 10:30 last night I did not get out of bed until 8 AM this morning.  Today’s weather forecast was for a 50% chance of rain with winds out of the WNW shifting to N at 15+ MPH and a high temperature of 50 degrees F.  The 50% chance of precipitation turned out to be an all-day drizzle; not an ideal day for working outside.  Nonetheless, I spent the late morning (post breakfast) working in our house electrical bay on the wiring for the Zena 24 VDC power generating system.

The only thing I actually accomplished was mounting a Class T fuse holder (with a fuse) to the ceiling of the compartment.  That was a bigger accomplishment than it seems, however, as its location determined the lengths of the cables needed to finish the project.  With a nicer day on tap for tomorrow I expect to get those cables made and installed.  A final check of the wiring and installation of the drive belts on the alternator will complete the project, which I stated almost exactly two years ago.

Butch and I went to Logansport in the early afternoon.  He needed plumbing parts for his fresh water tank and ITR Oasis Combi project.  I needed 2/0 lugs for my battery cables, some 3/8 compression nuts and sleeves, and some duplex outlet expanders.  I found the lugs at Rural King (where we also got some free popcorn) and everything else at Home Depot.  These stores happen to be conveniently located across the street from one another.  The nuts and sleeves will be used to rig up a hose or tube so we can test the water flow coming out of the pipes that feed the kitchen faucet.  The flow is much lower than it should be and we want to determine if it is due to the faucet or upstream in the piping.  I found a small duplex to 6-out expander that would fit under the thermostat on the end of the kitchen counter based cabinet.  I also found a duplex to 6-outlet expander with integrated surge protection and two USB charging ports.  I bought two, one for the outlet on my side of the bed and one for the outlet on the outside wall just behind the passenger seat.  This model is not illuminated like the one I installed on Linda’s side of the bed, but that’s OK.

We stopped at Butch’s parents’ house to investigate the source of a mechanical noise. It turned out to be a dehumidifier in which the fan motor bearings were squealing.  Butch loaded it in his truck to take back to his house where he could more conveniently try to oil the bearings.  We chatted for a while and then headed to Martin’s Supermarket so I could pick up a few grocery items.

When we got back to Twelve Mile I unloaded and stored my groceries and then installed two of the three outlet expanders.  I could not install the one by the passenger seat as the outlet was too close to a wooden structure.  There is an outlet box with a solid cover plate next to the duplex outlet and I will see if the outlet can be moved over.  If not, I will install this unit behind Linda’s night stand at our sticks ‘n’ bricks house.

Butch’s brother, Tom, showed up and the two of them worked on installing the Blue Ox base plates on Butch’s Suburban.  I spent the afternoon making a scale drawing of the passenger side of the front half of the coach showing the two Lambright Comfort Chairs, custom printer cabinet/table, and custom desk with pantry.  I checked in with Butch and Tom and helped them a little bit with the base plate project.  When they reached a stopping point, or at least a point where my assistance was no longer needed, I returned to my coach and fixed dinner.

I had a salad of power greens with cranberries and peanuts, some apple sauce, and the leftover Mjadra from La Marsa, the last of my frozen leftovers from our dinner at the Brighton location with Bruce and Linda Whitney.  A glass of Franzia Moscato was quite agreeable.  Butch and Fonda had not eaten their dinner yet, so I worked in the guest bedroom at my computer while they ate.

Linda called around 8:45 PM and chatted with Butch about an accounting issue related to their business and then chatted with me about our grand-daughter, Madeline, who is finally pronouncing words clearly enough to be understood and quickly developing a spoken vocabulary.  Brendan and Shawna brought her to our house around 11:15 AM this morning and stuck around through lunch to get her down for her nap and then took off.  Grandma Linda had her all to herself the rest of the day and will have her tomorrow until they pick her up.  I chatted with Butch and Fonda for a while after that and then retired for the evening, checking and responding to a couple of e-mails, doing a little web-surfing, and working on this post.

2014/10/19 (N) Of Mice And Men

Although I really enjoy Linda’s homemade granola I decided to make toast with some of the Brownberry Country White bread I bought.  I was surprised to discover that someone, or something, had chewed a hole through the plastic bag and eaten some of my bread.  A mouse, no doubt, but I only bought this bread on Tuesday, so it was a recent visitor.  The surprise was that the bread was in a cabinet that I assumed was inaccessible to mice.

I emptied the cubby and discovered a hole in the back wall big enough to stick my finger through for some distance, which meant it was plenty big enough for a mouse to get through.  The walls are covered with the same thin carpet that is used to line all of the other cabinets in the coach.  In this case it was applied to fairly thin wood with space behind it.  Butch looked at it with me and we found that the glue used to install the carpet had lost much of its hold.  We lifted it up and found a 2″x2″ cutout in the wood with the hole in the carpet roughly centered on it.  There was a Romex electrical cable coiled up behind the wall with the ends taped.  We presumed the wire had once passed through the hole into the cubby but was now a way for the mouse to travel vertically through the cavity and get to the back entrance.

I threw the bread out, of course and cleaned the counter surface, which forms the floor of the cubby, with Lysol.  Mouse proofing the bread cubby will have to wait until tomorrow but my plan is to feed the wire through the hole in the carpet and then lift the carpet at the bottom and run a bead of caulk (or hot glue) along the joint between the counter and the wood walls.  I will then install a surface mounted outlet over the hole.  At a minimum it will seal the hole and it might prove useful someday for plugging in an appliance, assuming the wires are still energized.

Although it was in the low 30s when we got up this morning, it was finally a decent day for outside work.  The high temperature only made it to the mid-50s but it was sunny most of the day with a light breeze.  Appropriate layers of clothing made for comfort while working.

My main focus today was completing the installation of the Zena 24VDC power generating system in the bus.  I started this project two years ago this month and today was the day to finish it.  I had also written a complete draft of an article about this project for Bus Conversion Magazine but held off finishing and submitting it pending completion of the project.  Now that the work is completed and the system functions correctly I hope to finish the article in the next few weeks.

The purpose of the system is to charge/maintain the 24VDC house battery bank while we are driving the bus, during which time the refrigerator, and other minor loads, are being powered by the inverter.  The system consists of a high-output, continuous-duty, 24VAC, 3-phase alternator driven by the main bus engine (Detroit Diesel 8V92TA).  The alternator feeds a large rectifier assembly in the house electrical bay and is controlled by three interconnected modules mounted in the engine bay near the alternator.  Redundant voltage sense wires run from the rectifier back to two of the three control modules.  The system is activated by ignition switched 24VDC power which we wired up a couple of days ago.

The unfinished part of the project involved the connections between the DC output of the rectifier and the 24VDC house battery bank.  I mounted a Class T fuse on the ceiling of the electrical bay yesterday which then allowed me to determine several cable lengths.  On the +24VDC side I made three cables from 2/0 welding cable as follows:  1) Rectifier DC positive to ceiling fuse terminal A; 2) Inverter/charger fuse terminal B to ceiling fuse terminal B, and; 3) Ceiling fuse terminal B to +24VDC battery disconnect switch.  With this configuration both the rectifier and inverter outputs go through separate fuses to a common point (ceiling fuse terminal B) and that point is connected to the battery disconnect switch.  I also made a cable to go from the rectifier DC negative (ground) to the house DC electrical system ground lug; again using 2/0 welding cable.

I used a metal blade hacksaw to cut the welding cable to length and cut through the heavy rubber sheath 1/2 inch from the end to expose the copper conductors.  I attached crimp style through-hole terminals to the ends of the cables and held them in position to get the alignment correct.  I made reference marks to ensure the alignment and then crimped the lugs onto the wire using a very large hand-operated press in Butch’s shop.  Projects like this are a lot more fun with access to the correct tools.

I attached as many cable ends as I could without touching any live voltages.  I turned off the Aqua-Hot, the UPS, and the inverter/charger before disconnecting the main AC shore power.  I then turned the +24VDC disconnect switch to the off position, isolating the coach/inverter from the 24VDC battery bank.  (Note, however, that I did not disconnect the 12VDC center tap.)  With power off I completed all of the needed connections, including the small ground wire for the 24VDC fan on the rectifier, turned the 24VDC batter disconnect switch to ‘on’, and turned the inverter back on.  It immediately started supplying power so I knew my wiring was correct.

Back in the engine bay I checked all of the wiring against my diagram and everything was good to go.  I taped off two wires with bullet connectors on the ends to prevent accidental shorting.  One of the wires is used to reset the system by grounding it and the other wire is tied to chassis ground.  With all of the electrical connections verified I got Butch to help install the two drive belts from the DD8V92TA pulley to the alternator (power generating module).  That was when we discovered that the lower side of the belts were in contact with a pressurized oil hose for the Spinner II centrifugal by-pass oil cleaner.

The hose was secured with zip ties in several places so I clipped and removed those.  I disconnected the hose from the Spinner II and re-routed it to avoid the drive belts and other rotating parts on the front of the engine (which faces the rear of the bus).  I reattached the oil hose to the Spinner II and secured it with zip ties.

Butch used a pry bar to move the alternator and put tension on the drive belts while Tom and I tightened the alternator mounting bolts.  The inverter had been supplying AC power to the coach for a while and a check of the house battery voltage showed +24.5VDC.  I turned on the chassis batteries and engine accessories air valve, started the DD8V92TA, and put it in high idle.  I re-checked the voltage at the rectifier output and it was 24.8, higher than before and rising, but not too high; an excellent set point at least for now.

We observed that some of the belts on the engine seemed loose and floppy.  Butch also noticed what appeared to be a stone embedded in the outside surface of the Gates Hi-Power II PowerBand A92 triple V drive belt that runs from the DD8V92TA crankshaft pulley to the drive pulley for the engine cooling fan.  Butch called O’Reilly’s in Logansport but they were unable to locate the 2.125″ wide triple-V belt in their system.

The oil dipstick tube was also too close to the new drive belts but when I tied to move it (bend it slightly) I noticed that it was very loose.  The fitting at the block was not tight and it was obvious that some oil had leaked out from there.  I slid under the engine from the rear of the bus and tightened it at the block.  (It is nice having the bus supported on stands so I can work under it without concern.)

While I was working on the Zena system Butch installed an outlet fitting on their fresh water tank.  He and Fonda, and eventually Tom (Butch’s brother), re-installed the tank in their bus and then mounted the ITR Oasis Combi next to it, securing it to the floor of the bay.  To accomplish that they had to drill holes, align holes, and determine a location for the water pump, which required more information regarding allowable pump orientation.  Sometime during the day Butch shifted his focus towards an antenna project on the roof of their bus.  He had previously purchased a Tarheel motorized fold-over mount for his large Tarheel screwdriver antenna and wanted to at least get the fold-over mount attached to the roof before they left for the southwest.

The key lock on our passenger side engine bay door was getting difficult to turn so I removed an access panel on the inside of the bay door to investigate the mechanism.  As I loosened the access panel water ran out the bottom.  We determined that the gasket surrounding the handle/lock assembly was dried out and cracked, allowing water in at the top.  I removed the handle/lock assembly by pulling it out of the door from the outside, dried it out, and lubricated it.  I reassembled it for now, but I need to apply some kind of sealant behind the gaskets or get new ones from Prevost (if they are still available).

Butch shifted his attention yet again, this time to their Suburban where he and Tom re-attached the front bumper.  It was removed a few days ago so he and Tom could install the Blue Ox base plate kit which will allow them to tow it with the bus.

As the sun dropped low in the western sky the temperature dropped along with it.  I buttoned up my coach and helped Butch get his tools and supplies moved inside.  I then went to my coach to have dinner which consisted of an Annie’s Spicy Mongolian noodle bowl with added peanuts and a tofu hotdog with mustard, onion, and relish.  A glass of Moscato with the meal and a cup of Oriental Treasure green tea afterwards provided a soothing and warming end to the meal.  I returned to the house and we chatted for a short while before I retired to my room to check e-mail and write.

2014/10/20 (M) Bad Timing

I have settled into something of routine on this extended visit to Twelve Mile, Indiana; up late, sleep late, eat breakfast, get to work.  Usually.  Butch spends the early morning on his computer and is usually ready to work about the same time I am.  Usually, but not always.  Sometimes he gets to work earlier than me, and sometimes much later.  Although we had a beautiful weather day (except for the brief thunderstorm around 10 AM) we were not able to take full advantage of it for various reasons.  I had left the Aqua-Hot turned off over night to see if it would start reliably when cold.  The burner fired after a short 10 second purge.  It was smokey at first, but ran its full cycle and eventually cleared up.  I turned it off and will test its cold start capabilities again tomorrow morning.

We discovered yesterday that the triple V fan belt on my bus engine was worn and had something embedded in it.  The belt was a Gates Hi-Power II PowerBand A92.  We spent some time looking for one online but were not sure we had found exactly the right one so I decided to see if Prevost had it in stock.  They did, and it was only a few dollars more, included free shipping (as always), and would be at my house before I got home.  I ordered two.  This belt drives the engine cooling fan and if it breaks the bus isn’t going anywhere until it is replaced.

Butch and Fonda worked on re-conditioning a pair of fan-coil heat exchangers that will get tied-in to their new ITR Oasis Combi hydronic heating system on the bus.  Butch and I had both been assembling shopping lists and I was at the point where I needed to get some small parts in order to move forward with some small projects.  We left around 11:30 AM and drove to Logansport where we visited NAPA, O’Reilly’s, Rural King, Aldi’s, Home Depot, and Walmart.  All of these stores are located close to one another on the east end of town except for the O’Reilly’s and NAPA which are just a bit farther down the main road towards downtown.  When it comes down to it, Logansport is just not that big.

By the time we got back it was after 3 PM and we were suddenly very busy as we tried to take advantage of the few remaining hours of daylight.  Butch and Fonda worked on installing the Tarheel fold-over mount and I worked on sealing the bread cubby, installing a Wiremold surface mount outlet over the hole in the back wall, and installing a small battery powered LED puck light in the back closet to illuminate the inverter sub-panel.  I cut a small triangle of thin aluminum for the hole in the corner floor of the bread cabinet and then sealed the joint between the floor (counter) and three walls with a silicone-based paintable tub and tile caulk in a convenient squeeze tube.

When I finished those tasks I checked in with Butch and Fonda and found out that they had run into problems with the Toggler(R) bolts Butch was using and had to undo what they had already done and seal up the holes in the roof for the night.  There wasn’t anything I could do to help at that point, so I started working on the wiring that will allow me to relocate the Magnum ME-ARC remote control/display module from the electrical bay to the house panel next to the refrigerator.  Rather than try to route the 4-wire telephone cable between the inverter/charger and the house panel, John Palmer had suggested two years ago that I re-purpose one of the existing cables that had previously connected the Heart Interface inverter/chargers to their remote displays.  All that was required was to attach RJ-11 plugs on each end to four off the nine available wires.  As long as I used the same four wires on each end, and got the colors in the same order, it should work fine.  Butch already had the necessary crimper and I bought a small bag of the plugs today at Home Depot.

Sunset is just before 7 PM these days.  It not only comes earlier, it comes quickly.  We were done working by 6:30 PM and I withdrew to my coach to have dinner.  I had a nice salad of power greens with sun-dried tomatoes, olives, garlic, artichoke hearts, dried cranberries, and peanuts with peanut butter and crackers on the side and a small glass of Franzia Moscato.  I cleaned up from dinner, closed up the coach, set the two small electric cube heaters for around 60 degrees F, gathered up a few things and went back to the house for the evening.  Butch and Fonda were just getting ready to eat their dinner so I retired to my room to work on my computer.

2014/10/21 (T) Fair Weather Ahead

One of the first things I do each morning, even before I have breakfast, is to check the current and forecasted weather.  The guest bedroom at Butch and Fonda’s place is an interior room with no windows and is well insulated, including the ceiling, so I have no visual or auditory reference to what is happening outside.  If not for the clock on the headboard of the bed (or my various communications and computing technologies) I would have no idea what time it was, or even if it was day or night.

There was widely scattered light rain across northern Indiana at 7:30 AM with single digit precipitation probabilities through the day dropping to zero chance of rain for Wednesday and Thursday with high temperatures in the mid-to-upper 50s.  That is about as good as it gets for the fourth week in October.  Hopefully it bodes well for our project work and will be a very productive few days.

Butch plans to attend a gun show on Saturday morning and needs to spend most of Friday getting ready.  Butch and Fonda’s family members (parents, siblings, children, etc.) are gathering at their house on Sunday to celebrate the holidays early since Butch and Fonda plan to be in the southwest with us this winter.  Given the weather forecast I will probably work the whole day on Thursday, spend the night, and then head for home early Friday morning, or at least as early as I can manage.

Butch’s main focus today was re-mounting his Tarheel antenna lift to the roof of their bus.  He figured out last night what parts he needed to make the installation work after his Togglers(R) broke yesterday.

My main focus was diagnosing and repairing the very low water flow from the kitchen faucet but before I got too deep into that project I called Prevost’s U. S. parts office in Elgin, Illinois to check on a couple of things.  They had the CX-96 cogged fan belts in stock in the U. S. but wanted $90 for a pair (they only sell them in pairs).  I found them last night online for $21 each, so that was a big difference.   They also had the bay door handle/lockset gaskets I needed but they were only stocked in Canada.  They were only $4 each, so I ordered the 12 I need to redo every door.

I found the installation and instruction manual for the Kohler kitchen faucet in our conversion binder.  It said that the handle and cover should slide straight off of the body once the handle set screw was removed.  Butch and I both tried this but we could not get it off.  While studying the diagram and parts list I noticed a “restrictor” that also served as an adapter from the 8mm outlet pipe on the faucet to the 1/2″ NPT fitting on the retractable hose assembly.  At Butch’s suggestion I shut off the bus fresh water pump, shut the valves on both the hot and cold supply lines that feed the kitchen sink faucet, and disconnected the supply lines from the inlet tubes that are part of the Kohler faucet.  I inserted the barbed end of the 1/2″ NPT adapter into a piece of rubber hose that I got from Butch and threaded the pipe thread into the cold supply line.  I placed the end of the hose in a bucket, turned on the pump, and then opened the cold supply valve.  I had lots of flow.  I closed the valve, shut off the pump, and repeated this for the hot supply which also had good flow.  That meant the problem was either in the restrictor, in the valve cartridge, or somewhere in the faucet body.  The good news was that the restriction was not in the upstream plumbing.

By mid-morning Butch was ready to make a parts run so I grabbed my short shopping list and rode into Logansport with him.  When we got back I disconnected the kitchen faucet hose from the restrictor/adapter and then disconnected the restrictor/adapter from the 8mm outlet tube.   The garbage disposal was in my way so I disconnected and removed it temporarily.  Initial inspection revealed that the restrictor was clogged so I started taking it apart and Butch finished the disassembly.  I reinstalled the adapter without the restrictor parts and tested the flow.  It was now very strong, which meant that the valve cartridge and valve body were OK and did not need to be serviced or replaced.  That was a good thing as we had not been able to remove the cartridge earlier when we tried.  With the water shut off I removed the flow restrictor/adapter cleaned out the entire assembly, and removed one small rubber O-ring.  I reassembled all of the pieces, turned the water on, and checked for leaks.  I did not see any so I turned off the water and cleaned up the area.

It was early afternoon by the time I finished the faucet project—too early to stop working on such a perfect weather day—so I started working on the wiring for the Magnum ME-ARC remote, which I want to relocate from the electrical bay to the house panel in the kitchen.  Because of the difficulty of running wires between these two locations I decided to follow John Palmer’s advice and re-purpose one of the two nine-conductor serial cables that connected the old Heart Interface EMS-2800 inverter/chargers to their remote panels in the house panel.

I decided to use the cable labeled #2.  I removed the snap-together Amphenol DB-9 connector from the house panel end and cut the molded DB-9 connector off of the inverter end.  I tried using Butch’s RJ-11 strip/crimp tool and discovered that the wire in the cable was one size too large to fit in the stripper so I stripped and trimmed them by hand.  The wires were stranded so I twisted them tightly but found that I could not get them inserted and lined up properly in the RJ-11 connectors I bought at Home Depot the other day.  Ugh.  Time for Plan B.

While we were working today plans got made for dinner at the Hibachi Grill Supreme Buffet in Kokomo, Indiana at 6:30 PM.  I decided to drive myself and leave early enough to go to Discount Tire in Kokomo and have them balance all four of my tires.  They closed at 6 PM so I stopped working around 3:30 PM, changed into cleaner clothes and headed for Kokomo at 4:15 PM.  Kokomo is about 30 miles south of Twelve Mile and takes about 45 minutes with speed limits and stop lights.  It used to be on US-31 but Indiana has made significant changes (improvements) to US-31 so that it is now a four lane divided limited access highway in many places and bypasses a lot of towns, including Kokomo.  What was US-31 is now SR-931.  Why they named it that instead of “Old US-31” as they have done in other spots is a mystery to me.

Before I got to Discount Tire I passed a Gordon Food Service (GFS) and a Menard’s located next to one another.  I needed things from both but wanted to get the car taken care of first.  Discount tire said it might be 90 to 105 minutes before they could get to me.  I could not wait that long but had them write it up anyway.  They took my car in about 25 minutes later and had it done in another 15 minutes, so I had time to do some quick shopping.

I got a package of 25 16 oz. hot cups at GFS to go with the lids we already had.  At Menard’s I got two surface mount 4-wire phone jacks and a double-ended phone cord for my Magnum inverter/remote project.  Butch and Fonda also stopped at Menard’s looking for dryer vents to use with their bathroom and shower ventilation fans.

Dinner at the Hibachi Grill Supreme Buffet was a family gathering.  Beside Butch and Fonda (and me) we had Butch’s mom and dad, his sister Robin and her mother-in-law Betty, Butch’s brother Tom and his wife Tracey, their son Brock and his wife, and another young couple and their kids.  I think the wife was Tom and Tracey’s daughter.  There were four or five kids whose names I did not get.  We all ate too much.  The food was OK, but Butch’s family and the conversation were more interesting.  It was 9 PM by the time we got back to Twelve Mile and I headed off to bed to take care of correspondence and writing.

2014/10/22 (W) Plan B

You always need to have a “Plan B,” or be prepared to come up with one on short notice.  Backup plans are not a sign of indecision or a lack of commitment to a primary plan.  Rather, they are an acknowledgement of the reality that things do not always work the way you thought they would no matter how brilliantly conceived, carefully planned, and skillfully executed.  So it was with my inverter/remote re-wiring project.

I spent most of the day working on the wiring that would allow me to move the Magnum ME-ARC remote from the electrical bay, where it was plugged directly into the Magnum MS4024 inverter/charger, to the house systems monitoring and control panel next to the refrigerator.  It was simple enough in concept, but I had to make sure it was correct as I did not want to damage the inverter or the remote unit.

I used four of the nine wires in one of the old serial cables (#2) that runs from the electrical bay to the house panel.  Since the phone line cables with the RJ-11 plugs on the ends used Black, Red, Green, and Yellow I decided to stick with those colors all the way through.  However, because of the way the RJ-11 connectors are assembled onto the cable the signals move back and forth between pins.  I ended up wiring the cable end in the electrical bay to the same color wires in the baseboard outlet and mounted it to the ceiling of the bay.  I cross-wired the other end of the cable to another baseboard outlet and mounted it to the side of the cavity behind the house system panel.  Fortunately the back side of the panel is accessible via a removable panel in the back of the closet that is on the other side of that wall.

With all of the wiring done I used a jumper with alligator clips on each end to bridge two of the wires in the electrical bay outlet and do a continuity check at the house panel outlet to verify the wiring.  Everything looked good so I unplugged the remote, brought it inside, and plugged it in.  It worked!  Now all I had to do was mount it.

There were already two cutouts at the bottom of the house systems panel from the old Heart Interface EMS-2800 remotes (the coach had two of these inverter/chargers when we bought it and each one had its own remote).  The cutouts measured 4.625″ W by 2.875″ H.  The housing on the ME-ARC was slightly wider than the opening but not as high.  Depth was not an issue.  I borrowed a small roto-tool from Butch with a small router bit and carefully opened up the left hand edge of the right hand cutout.  Using the remote as a template I marked the locations for the four corner screws, moved the remote out of the way, drilled out the holes, moved the remote back into position and attached it to the house panel using four #6 machine screws and Nylok nuts that I got from Butch.

While I was working on my project, I periodically asked Butch if he needed any assistance, but Fonda was providing the needed help.  They managed to mount an 18″ H by 24″ long piece of 3/4″ plywood to the back wall of the Oasis/water bay with a 1/4” heavy rubber separator between the wood and the metal.  Butch then mounted their Shur-Flo 4048 water pump to the plywood.  This should cut down considerably the noise and vibration transmitted from the pump to the structure of the bus and into the living quarters, but only experience will prove if that is the case.  Butch moved their fresh water tank slightly to make room for their portable water softener.  They also installed the two dryer vents, one on each side of their bus, which they picked up at Menard’s last night.  Their final project for the day was to cut a hole in the roof and install a right angle cable junction box that will be used to route coaxial cable and other lines from the roof into the passenger-side cabinet in the bedroom at the rear of their bus.

I looked at installing the remote readout for our Progressive Industries EMS-50 and decided it was more work than I wanted to start late in the day.  Butch suggested that I do it the same way I did the Magnum remote, re-purposing some of the wires in the old serial data cables.  That was going to require additional parts, so I started a list for my next trip to town.

My final project for the day was to try and fix the lighted entrance handle and the non-functioning patio light.  The lighted entrance handle had a badly deteriorated gasket behind the top securement so I fashioned a replacement from a piece of heavy vinyl shower pan liner that Butch and Fonda had.  The bulb was an LED I installed some time back.  It was still working but the socket was loose so I tried to squeeze it down a bit.  Butch pushed the spring loaded center section out, stretched the spring, and put it back in.  The bulb is now nice and tight.

The patio light proved to be more difficult.  The lens was cracked and difficult to get out but I finally did.  It’s a florescent fixture with two F8T5 bulbs.  I tried turning them in their lampholders but that did not help.  I pulled the wires far enough out of the wall to find two butt connectors.  I was able to get my multimeter probes far enough into one end of each connector to verify the presence of 13 VDC that was controlled by the same switch as the lighted door handle.  I removed the two bulbs and tested them in the fixture over the kitchen sink.  They both worked fine, so the problem appeared to be the ballast.

The way the fixture is designed there was no way to get to the ballast to replace it so I put the bulbs back in and got them to glow faintly.  I tried to replace the lens, which was already cracked, and the top inch split off all the way across.  Fonda though she could fix the cover and epoxied the two pieces back together.  While the epoxy was setting up I noticed that both lamps had come on full bright.  By the time Butch reinstalled the lens they had both gone out.  Definitely a bad ballast.

As it turned out, Butch had an almost identical brand new fixture that he did not intend to use.  The only difference was that his fixture had an on/off button on the underside whereas the one on our coach has a plastic plug in that hole.  His fixture has black end caps, which is fine, and is not painted to match the color of our coach, which is also fine.  Removing our current light fixture will be a bit of project and will have to wait until next week.

I ended up going to Logansport at 7:15 PM for a few parts that I would need tomorrow.  I got back around 8:30 PM and it took me 20 minutes to get my dinner ready and take it into the house.  I was straightening up the bus after dinner and looking for a new roll of paper towels for the kitchen when I discovered a mouse nest in the small cabinet between the sleeper/sofa and the kitchen base cabinets.  I put on nitrile gloves and cleaned it up and then inspected the compartment.  It was open at the back to the area above the HVAC chase that is part of the bus.  The more I have peaked in and under cabinets the more I have come to realize that our coach is a lot like Disney World; there is a network of passageways that are hidden from view but interconnect the bays with the areas behind and under cabinets and furniture, providing an subterranean road system for small critters.  It’s always something when it comes to bus conversions.  The long term challenge will be to figure how where the critters are getting in and see if we can plug those ports of entry.

 

2014/04/07 (M) Big Wheels Keep On Turning

The boots may have been made for walking, but the wheels were made for turning and it does not make much sense (to us) to own a motorhome and not use the motor to move the home around at least occasionally.  Checkout time at Williston Crossings RV Resort is nominally 11 AM.  We were planning to leave by then, but a call to Suncoast Designers at 9 AM caused us to push our departure time back.  They suggested we not arrive until about 4 PM to make sure we had a place to park with hookups.  That put our departure time target at 2 PM.  We walked up to the office to make sure this would be OK.  It was; we have been here a long time and been good residents, and no one was scheduled to go in to “our” site today.

Given some extra time we had not planned on, we went for one last, long walk around the RV resort.  How different it looked and felt.  The resort is turning over from long-term winter/seasonal use to short-term summer/vacation use and there were many empty sites.  Eighty-nine rigs left yesterday.  Many were Carriage 5th wheels that were part of the 70 rig Carriage Travel Club rally that was here all last week.  But some were winter seasonal residents who have been dribbling out since April 1st and will continue to do so into May.  We were not the only rig pulling out today.  Our other neighbor, Sharon, is leaving this coming Sunday.  A few rigs were pulling in, of course, but the departures currently exceed the arrivals on any given day.

When we returned from our walk I mixed up a batch of the concoction we use in the waste holding tanks (48 oz PineSol, 48 oz water, 1cup Calgon).  I dumped the black-water tank and back-flushed it, followed by dumping the grey-water waste tank.  I ran additional water through the drain hose and then disconnected the hoses and fittings and stowed them for travel.  I reconnected the water softener and filled the fresh-water tank.  Once that was done Linda helped me disconnect, clean, and stow the fresh water hoses and the water softener.

We tend to forego coffee and breakfast on travel days, but had a little of both this morning as we were not leaving right away.  Because of the delay in our departure we did not have lunch.  To pass the time I continued with travel preparations.  The last time I had the coach batteries connected I noticed that the Pressure Pro TPMS (tire pressure monitoring system) was not reading one of the sensors (PS outside drive tire).  We have a repeater for this system that I plan to install in the rear of the coach someday, but for now it gets attached to the rear view mirror of the car.  I took care of that task and then decided to move the car up onto the patio next to passenger side of the coach.  I left the ignition on to power the repeater and connected the coach batteries to power the TPMS receiver.  After a few minutes all of the tire sensors were active and the tire pressures were OK for travel.  I disconnected the coach batteries and put the car back in front of the coach.

At 1:30 PM we started our final travel preparations, clearing off the counters and moving stuff from the cockpit to the sofa, the bed, and the bedroom floor.  At 1:45 PM I shut off the 240/120 VAC electrical power to the coach, disconnected the shoreline, and stowed it in the slide-out tray over the DS drive tires.  I installed the screw-in cover for the utility port hole in the bay floor, and closed/locked the bay.  I then checked the Magnum 4024 to make sure it had switched to inverter mode, which it had.

Once the shore power is cut we seem to develop an increased sense of urgency about leaving.  I think this is due, in part, to the fact that I do not have the ZENA power generator operational yet, so our house batteries do not get charged while we are driving.  That’s OK, up to a point; the battery bank was designed to be large enough to run the inverter and power reasonable loads for a reasonable length of time.  But the sooner we leave, the sooner we arrive, and the sooner we arrive, the sooner we can plug back in to shore power.  We have an auxiliary power plant, of course, so we always have the option of using that if needed.  The other reason we are probably anxious to leave is more psychological.  Once we are completely disconnected (physically) we are become disconnected mentally, although not necessarily emotionally.  We are no longer “tethered” to that spot, and that means it is time to go.

I connected the chassis batteries, fired up the engine, and set the level low system to the driving position.  While Linda moved the car to street I drained the auxiliary air tank using the nice dry air from the main engine air compressor.  With John’s assistance we got the coach out of the site and lined up on the street.  Linda pulled the car up behind the coach and we went through our procedure for hooking it up to the tow bar.  We did our standard light check and found that the turn signals on the car were not working.  A quick check of the connectors on both ends of the cable revealed a socket on the car end of the cable that was corroded.  I used the awl on John’s Swiss Army Knife to clean it up.  A recheck of the lights indicated that everything was working.  After a final “goodbye” with John and Ali we were on our way.

Our departure delay meant we would be traveling SSW into the sun at the hottest part of the day.  The air temperature was 85 degrees F when we left, and the engine ran slightly hotter than usual, indicating just above 195 degrees F on the coolant temperature gauge, so I decided not to run the coach air conditioning.  The drive to Hudson was warm, but not unbearable.  A cold front was approaching the gulf coast of Florida so we had increasing cloud cover as we progressed south and west towards the coast, which helped keep the cockpit from getting too warm.

We had a nice run from Williston to Hudson.  We headed south out of Williston on US-41/US-27/FL-121.  US-27/FL-121 split off to the west a mile south of town, made a sweeping turn to the left and then followed a nice straight line SW for 17 miles to its southern terminus at US-19.  This stretch of FL-121 is straight but hilly.  With the cruise control set the engine is very sensitive to hills.  I always know we are on a grade, however slight, by the reaction of the turbo boost gauge and the pyrometers.

Most of the rest of trip was on US-19 except for the last three miles.  Traffic was light until we got to Crystal River, which had slower speed limits, lots of stop lights, and lots of vehicles on the road.  It opened up a bit after Homosassa Springs, but got congested as we approached Weeki Wachee where FL-50 ends at US-19.  From Weeki Wachee to just north of Hudson traffic remained slow and congested with increasingly dense commercial use on both sides of the road and stop lights every mile.  Just north of Hudson we turned east onto Little Road, which immediately swung south, and followed it for about two miles to New York Avenue, where we turned west and went another mile to Labor Place, the location of Suncoast Designers.

The coach ran fine, although the Check Engine Light came on almost immediately and was on more than it was off for the whole trip.  That did not surprise me as we had not done any work over the last couple of months to fix the fuel temperature sensor voltage problem that is apparently setting a fault code in the DDEC II.  I had hoped that the repairs we made in the dashboard wiring harness would fix the speedometer/odometer problem, but they did not; the gauge sat on zero for the whole trip.  The left pyrometer (exhaust gas temperature) gauge, however, was much more responsive and tracked the right pyrometer gauge much more closely than it ever had before.  It appears that the wires we repaired were for this gauge rather than the speedo/odo.

Once we pulled in to Suncoast Designers we pulled to the side of the road, so as not to block traffic, and unhooked the car.  While Linda parked the car I found the office and checked on parking arrangements.  Suncoast Designers has at least a dozen RV sites with water and 50 A electric hookups.  The only one open was a somewhat tight spot between two other large Class A motorhomes that required me to back in.  The maneuver was made more difficult by the fact that the road in front of the sites had a curb on the far side and was not wide enough to allow me to swing the front end without scrubbing the front tires.  I repositioned the coach so that I was turning in from the driver’s side, but Linda and I could not figure out how to get the coach into the site.  The guy next to us on the driver’s side offered to help.  A former truck driver, he knew exactly what to have me do.  Unlike some RVers, our pride is not injured by not knowing how to do something, and we gladly accepted his help.

I pulled past the site close to the front of his rig and then turned out to the passenger side, putting the coach at an angle to the open site.  He had me back part way into the front of the site at that angle and then turn the steer tires full left to start to bring the coach around.  He had me stop and then turn the steer tires full right and pull forward.  Steer tires full left again and back up some more, then full right and pull forward. We repeated this one more time and finally had the coach lined up straight and centered between the coaches on either side without having hit either one!  Linda was keeping an eye on the back of the coach the whole time (to make sure I did not hit anything) and guided me into our final position.  We then leveled the coach and shut the engine down.

The outside air temperature was only in the upper 70’s, but it was 90 degrees F in the coach and the outside humidity was high.  In spite of having nine windows that open, the three ceiling vent fans are not very effective at cooling down the interior under such circumstances.  In theory we can run all three air conditioners on a “50 A” shore service, but we have tripped breakers before when doing that.  (The issue is that circuit breakers are commonly designed to only carry 80% of their rated current on a continuous basis, so two of our A/C units plus a little bit of miscellaneous load can exceed 40 A on one of the legs.)  Besides, as soon as I plugged in the Magnum 4024 was going to switch to charger mode and start recharging the house batteries.

I got the shore power connected and checked the Magnum 4024.  It went into bulk charging mode and started charging the house batteries at 86 Amps. Since it is a 24 VDC charger, it was drawing ~1/5 that much AC current, or ~17 A, the equivalent of one of our air conditioners.  The front (living room) and center (kitchen) A/C’s are on separate legs of the 240/120 VAC power supply, so we can run them at the same time.  The bedroom A/C is on the same leg as the front A/C and the Magnum is on the other leg.  We ran the front and center A/C’s along with Magnum and let the bedroom stay warm for the time being.

Suncoast Designers provides free WiFi for customers camped at their facility, but the signal we thought was theirs indicated it was “filtered” and we had not obtained the login information from the office before it closed.  We used our Verizon MiFi instead and had a good, strong signal.  I had a chance to ask our neighbor (helpful truck driver guy) later, and he said the open signal was the one they were using.  Although it was a weak (one bar) “g” signal, our WiFi Ranger latched on to it without difficulty.

Linda needed a few grocery items and located a Publix grocery store on Little Road less than three miles from Suncoast Designer’s.  As evening settled in we switched off the front A/C and turned on the bedroom unit.  Linda reheated some of the leftover Sloppy Joe’s from the pot luck dinner the night before, and we had that on the skinny buns we have started using, along with a simple spinach salad and a few Fritos corn chips.

After dinner Linda sent e-mails to several of our new friends from WCRVR while I checked in to RVillage and took care of a few e-mails of my own.  The overnight temperature was forecast to only drop into the upper 60’s with high humidity, and with rain starting before sunrise, so we decided to leave the rig closed up and the kitchen and bedroom A/C’s on all night.  We rarely do this because of the noise and because we prefer fresh air, except when it is too warm and/or too humid.  Considering that we had traveled less than 100 miles and been on the road just under two hours today, we both felt like it had been a very long day.  As much as we enjoyed the social life at WCRVR, it was nice to not have anything to do but go to bed and get some rest.
