Customer Question

Randall, I have a 2005 Holiday Rambler Neptune. I am having an issue with my chassis batteries draining when running my generator. This wasn't always the case so something has changed. Batteries charge fine with engine running. Also, house batteries seem to charge well on generator or shore power.

There isn't any tie between the engine batteries and the generator in MOST cases. The only way they would is if they engine battery was used to start the genset. I would start by checking them to be sure they don't have one with a short. They don't ordinarily get any charging when the genset is IF you have a short someplace in the chassis wiring that would drain them. Have them load tested to be sure. And if there was any changes in the wiring or the batteries were taken out recently, let me know. All follow ups are included in our fee. R.J.
