Don't know about your particular Outlaw -- but if you have a BIRD there are probably also isolation relays (Trombetta) under the hood as well. The BIRD/Trombetta is designed to sense the charging state of the house and the chassis batteries and the BIRD causes the isolation relays to open and close to charge both the house and chassis batteries.

Here is a diagram and explanation of how that combination works. It sounds like an isolation relay (Trombetta is not working). I've also attached a picture of where the Trombetta is under the hood of my 2015 Vegas. Yours should probably look just like that.
