Topic: Generator causing dead battery fault (Read 93 times) previous topic - next topic

I had repairs to the Onan LP generator which ended up being a leaking propane line and the circuit board was arching (not so very far from the propane leak, however I'm still alive the Unity did not explode).  Now the generator purrs nicely, starts up fine, but two issues: (1) it works fine as long as the circuit breaker is off, which isn't too useful; (2) when the shore power is detached, the generator dies after 5 seconds, and a dead battery error shows up on the monitor.  House batteries are OK on testing, charged.  Resetting the generator a couple times did not resolve or change the issue.

Anyone have an idea where the disconnect, short or whatever that would give one or both of these issues.  Would like to understand it a bit better before going back to the repair shop and having them dither about at $195/hour.
