It's ok! All turned out well. The inverter has a search knob...mine was basically sticking...after a few back and forth turns if the knob and it worked perfectly! I got that advice from the manufacturer, great advice, but cost him a $1,200 sale.

Sorry my post is a bit confusing, I had too many characters in it and had to delete a bunch to send it. Basically I can't find what's wrong with the 12 vdc system and don't know if I'm reading the panel correctly.
Again...sorry for the mixed up text

I'm trying to learn the electrical system...wow complicated.
I ended up replacing all my batteries--chassis battery was original and spent...so it's gone, replaced with Energizer 64 group--850CCA.
The four 6v coach batteries are from 2008--they were very low on voltage, swollen, and dry with plates exposed. Now as I think about it, they never did start the generator...
So here is my two questions I'm hoping you can address:
1. The panel over the entry door...shows 14.5 volts, the % was 25 then dropped. Charge was bulk. This is with the new batteries installed and a charge on the system. Why 25% charged? And then dropping? I try cutting all power usage, and at one point plugged into a 120 15 amp power cord. No increase. Not even from the generator (which starts right away on the new batteries). Battery voltage is 13.5...charge voltage is 14.5.
2. When I check the panel in the bathroom (press test) lights come on but do not give me an indication of battery.

I couldn't help but notice your MH...we just purchased a 2000 la palma...pick it up next Monday! Same color as yours, our floor plan and model number matches a 2001--is that normal??
So any advice for me? Anything I should do or not do? It has 22k miles and original tires (I'm replacing them on Tuesday).
Thanks for letting me be nosy!
