Got a good one here, lol.
We've had the van a few months now, and it has always worked fine. I have left it on shore power at the house for the last couple weeks while working on the bed situation.
When the van is running, everything charges fine. When running off of shore power, nothing works. Here the tests I've done so far:
getting 14= volts at isolator/CB and coach batteries
Van off/Shore power
4.5v at coach batteries, and at both ends of CB on isolator
Found a 40A fuse melted coming off my isolator (battery side) going to my flex lite electric fans. There is the 40A fuse that is in line with the fans connected to a bus bar, then an additional 40A fuse between the bus bar and the isolator. Not sure how this has anything to do with my shore power problems.
I have 2 AGM 6v coach batteries.
In the second pic, are those both CB on top of the isolator? The one on the right is where I'm getting the 4.5V and the 14.5 volts.
