Ed,
Thanks for reply. My mind was telling me about the same thing, even in my electrical challenged state. Hadn't thought about taking out the two batteries that are getting very hot. I believe the charger is not over charging, they just are not accepting a charge. I tested all four with my hydrometer and the two that are getting so hot are all very bad. The other two batteries each have one bad cell and the other cells are close to bad but that's the best I can do. I did a bit of studying and decided to take the two worst batteries out of the equation. Only thing that threw me a bit was that there are two main ground cables, one hooked to each bank of batteries. Finally decided that if that ground cable was hooked up it should stay hooked up. Crossed my fingers when I turned everything back on and it appears to all be working. No more two very hot batteries is the good thing.
We are heading to Sequim and have an appointment at Eric's RV Performance center for the 10th, may be able to get it done on the third when we get there. Found them through Interstate Batteries. Just checked their web site and I believe I had some work done on my hitch by them at Quartzsite this past Jan after the Beaver Rally. If they are as good about this as they were on my hitch I'll be very pleased.
One other question, if you're running down the road and turn on the generator, it does the charging of the batteries rather than the alternator. This has been my assumption and have run the gen a lot the past couple legs of the trip as I don't want to fry the alternator. Thanks again.
Don
