I was up at 7 AM, fed the cats, and settled in on the sofa with the heater pad on my lower right back to work on my iPad. I finished my blog post for yesterday and e-mailed the last three days to myself. I updated seven apps and then checked out the latest issue of the SKP Photographers BoF newsletter. Linda finally got up at 9:15 AM. I made a pot of coffee and we had toast for breakfast.
My first priority after breakfast was responding to a half-dozen e-mails from Gary at BCM, one of which required me to proofread an article he had written about a recent rally. Next I selected four photos I took with our new Sony a99v DSLT camera and uploaded them to a Dropbox folder for Lou to see. Somewhere in there I got a call from Joe (our mobile mechanic) about Globus cork flooring products. As long as he was on the line I asked his opinion about the chassis battery / Vanner equalizer issue. He reminded me, as he often does, that I already knew how to check if the Vanners were working. When we concluded the call I went outside and did the checks.
With the Vanners connected to the batteries and working correctly the voltage at the “12V” terminal should be exactly 1/2 the voltage at the “24V” terminal. Equivalently, the voltage from +24 to +12 should be the same as the voltage from +12 to Ground. I unplugged the two maintenance chargers to let the surface charge bleed off and used the time to trace the wiring behind the two battery disconnect switches. As I somewhat expected the two Vanner equalizers, which are wired in parallel, are NOT connected to the batteries when they are disconnected from the coach electrical panels. (The one Vanner whose label I could see is a Voltmaster 60-50M rated at 50 Amps maximum so I presume the other one is the same model.)
With the battery bank connected the relative voltage measurements were as expected, indicating that the Vanners were probably working correctly while the absolute measurements of +25.6 and +12.8 (to the nearest 0.1 VDC) indicated that the batteries were fully charged.
I put the disconnect switches back in the disconnected position and plugged the maintenance chargers back in. I checked the voltage on the upper and lower battery strands and they were close to the same but not identical. That was reasonable given that the chargers were independent (electrically isolated) and the upper and lower strands were bridged by Vanner equalizers just minutes before. Based on my testing it appeared that everything was OK except that I lacked a plausible explanation for why the engine alternator apparently did not fully charge the batteries yesterday on the drive down from Mayo. I wrote all this up in an e-mail and sent it to Joe, Butch, and Chuck, all of whom have had conversations with me about this over the last few days.
Linda made a humus and onion on rye sandwich and we split it for lunch along with some grapes. It rained hard while we were eating but the rain did not last long. After lunch I completed the certification paperwork for our FMCA Freethinkers Associate Chapter. It was 4:15 PM by the time I was done. I will get copies made tomorrow and get it in the mail to the headquarters in Cincinnati, Ohio.
I logged in to the Prevost Community website to renew our AITA NAPA discount card but wasn’t sure what to do, so I called Chuck. He and Barbara were at a wine and cheese gathering and he said he would call me back when he was free. Linda wanted to go for a walk around the Resort so at 4:30 we headed towards the north end. This part of the Resort has had a lot of development since we were last here and now has a lot of new park models and large pads for RVs.
We looped around to John and Ali’s 5th wheel but did not see any sign of them so we headed down the main road towards Jeff and Kathy’s site. Sure enough, John and Ali were there enjoying a glass of wine with Jeff and Kathy. They offered us some and we accepted and pulled up a couple of open chairs. We sat and visited until 6:30 PM when we started to get some persistent rain drops. John drove us back to our coach in his golf cart.
For dinner Linda made a nice green salad and pan-seared tofu with a balsamic vinegar, soy sauce, and sugar glaze with chives. It was very good and I could easily have eaten twice as much. After dinner I worked on an article about replacing the bearings in our Aqua-Hot Webasto burner this past winter while we were on Quartzsite. I got the text finished and inserted/captioned the photos that had been post-processed. There are more photos to be processed and I plan to finish the article tomorrow and upload it to the Dropbox for proofreading.
I need, and have been looking forward to, a stretch of quiet days with time to work at my computer as I have a lot to do. I need to update our website and blog, which is almost four months behind, and get back to work on the SLAARC, FMCA Freethinkers, and FMCA GLCC websites. I also need to finish some articles for BCM that have been “in process” for quite a while, and I need/want to write some new ones. Along the same lines I need to clean up my BCM folders on my hard drive and in our Dropbox. That is not all going to happen by the time we leave for Arcadia, but I will do as much as I can. Once we get to Arcadia we will be spending more time away from the coach exploring southern Florida and visiting with friends. That means I will be creating lots of new photos and posts but have less time to process them. Ahhhh, retirement.
