Generac generator battery

I have a 2010 Georgetown 330TS with the factory installed Generac 6500 generator.

Just back from doing my monthly RV and generator start/run/exercise of the unit. I have always had the house batteries turned on when testing (to provide a load for the genny by using electric heaters) but just wondered if anyone knows for sure whether the generator actually gets it's battery for start up from the house batteries or the chassis battery under the hood.

Thanks

While I'm extrapolating from my 2007 to your MH, my generator starts on the house batteries. It would make sense to leave the engine battery alone because getting home is more important than running some electrical stuff. Plus, the engine will charge the house batteries as you drive so that the generator could be started eventually.

Went out last week to take mine for an exercise drive and to run the generator and A/C units since they pull the most current and the engine battery was dead. I used the house battery switch to give me enough juice to start up. It gave me new appreciation for how these crazy, rolling boxes are designed.

Drive safe.

Mine gets power from the house battery. The reason I know I had the house batteries main switch off while driving and wanted to start the generator and it wouldn't turn over at all.

That is a way to test yours.

The only load I've seen on dwgs and my own units for the Chassis battery is the starter for the engine. Minor exceptions are lights and radio. With newer units the brake hydraulics borrow from the chassis batterery for emergency braking if steering hydraulics fail. Everything else behind the firewall is powered from coach batteries or shore power/generator.
