The alternator first charges the chassis battery to full and then will provide charging to the coach batteries but at a slow rate. Fastest way to charge the coach batteries is with the engine running start the generator and charge the coach batteries that way

So, our gen will not start with engine running. Is gen start provided via coach batts?
You should have a momentary switch that connects the house batteries to the start circuit, you push that and start the generator if affect you are jump starting the generator. At least thats how my Class A worked
