normally the house and chassis batteries each have a ground to the frame. The house has two hot leads as does the chassis, the house one to the house and one to the boost solenoid and the chassis has one to the chassis side and one to the boost solenoid. The hot wire to activate the boost solenoid is usually from the chassis side. So if the chassis battery is truely dead there is no power to activate the boost solenoid and start the RV motor itself.
