Battery showing "E" 2016 364
So I took my rv to the shop for a little over a month, maybe 6 weeks while they fixed roof and some other things. Most of time was waiting on parts to ship for radius.
Anyways, got it back and first trip out my batteries are on E even after plugged in for a full 3 days before we came out to camper.
Did dealer leave on and kill? He had it plugged in when I got there, so wondered if he left it on and ran it down? Any other reasons? It's always showed full or almost full prior to this.
Any tips on what I can check would be appreciated. I have power for everything in coach, not running acs as weather nice but things that don't run on 12v all run so I know connection is good.
