When activated, the house battery disconnect solenoid removes the battery from the system during a period of storage or non-use. The house and engine batteries remain separated so it will have no effect on the engine start battery. Also, if the solenoid is activated while the coach is plugged in to shore power, the battery charger will not be able to charge the house batteries since they are now “disconnected” from the system. So typically you’d activate the disconnect switch during storage so the battery won’t be drained. But when using the coach, leave it off.
