If what Jeff says is true, front- House, rear- Start, then what I said isn't right. To get the engine started, hook the charger up to the rear battery. To get the House battery up to speed hook up to the front . this assumes there is no functional intertie till late in the charging cycle or maybe none at all.
Jeff- under what conditions does your setup charge both batteries? e.g. on mine (Vansco multiplexing) the engine will charge both batteries while running, the inverter/charger will charge both banks after the House bank gets up to a certain level, the generator will power the inverter/charger & will charge both banks after the House bank gets up to a certain level.
