Batteries not charging

[7633fleet]

08 Fleetwood expedition,about 2 weeks ago the 15 amp breaker in the small
Bathroom tripped.since then both sets of batteries will not charge from shore power,I did a inverter reset with no luck,read about the 200 amp continuous selenoid near the inverter sometimes goes out,replaced it no luck!the weird thing is the voltage gauge in the front that you press to check batteries is doing something strange.when I noticed the problem it showed both of them at 11.98 I replaced the batteries 3 years old,and the gauge showed 11.98 with the new batteries,now a week later it shows 12.4 but never the normal 13.4 as before,I’m in cold weather and if I run the furnace it runs down the batteries ,any help would be appreciated

Did you look on the inverter/charger for circuit breakers ?

If not, find it and look on all sides for them.

The solenoid you changed wasn't your problem, you need to stop throwing parts at it. Every time you do, you risk creating another problem.

On shore power, the inverter/charger charges the batteries, directly thru the large battery cables, no solenoids in its path.

The batteries also charge from the engine running, if you had it running, that explains the rise in voltage.

Yes I already reset the breakers on the side,and the change in voltage in the gauge happened not starting the coach it did it by itself,running the coach will charge both batteries to 13.6.

I just went thru this battery problem. After months of trying to save them, I came to the conclusion that they were gone.

i just replaced them. I didn't realize how much I was fretting about the issue until I did.

Welcome to the forum. You'll find a lot of help here.

Good luck.
