I've heard about house battery issues from fellow Winnebago owners for some time and see the same here in the Winnebago forum.

I've had both the problem of the house batteries not charging from the engine alternator AND the house batteries draining (40 milliamp draw) even with everything shut down (Aux Bat off, inverter off, panel off).

Today my dealer called with what seems like really good news. Working with Winnebago they located a grounding problem in the forward circuit breaker/relay bay of my '05 Journey. I was told this is directly causing the drain on the batteies and also preventing the "engine run" relay from engaging. This relay has to engage for the engine charging system to be cross-connected to the house electrical system.

What I was told this is a Freightliner XC chassis problem and could extend back over at least a couple of years.

I won't be picking up my coach until 5/28. I'll let you know what the final results are after that.

Had the coach back for a while and, yes, the problem is really fixed. The house batteries charge on the road as long as Aux Batt is set to On. Before the grounding problem was fixed this was not the case.

In fact, with the engine running I can draw 1000 watts on the house side with no net loss on the batteries.

There is no FCCC TSB for this (yet, I'm poking at them). In the meantime just tell your dealer to check the ground for the relay that controls this funtion.
