Question Chassis Batteries Dead

We've been gone for 5 weeks (since Sept 18th) - RV in the garage plugged into 50amp power... Came home yesterday, and the RV shows 2volts on the chassis batteries. Not sure what happened. The AC history shows a brief outage, but only less than a minute. I thought the chassis batteries were trickle charged from the house batteries when plugged in.

I had the a similar problem this spring. In my case, the Inverter wound up not charging either battery bank, so I had to replace the inverter. You may have a defective relay, blown fuse at the relay or defective batteries. Silverleaf can help you diagnose it. (541-967-8111) But, you need to charge your chassis batteries with an external charger first before calling them. Your coach will not charge dead batteries, and it needs to see a certain voltage (?) before charging begins on that bank.
Safe travels!
