12v Isolator Problem, Ford Chassis
Do I potentally have an isolator problem on my 97 31 ft with ford chasis:
Parasidic drain for vehicle battery always...good for sitting only about a week before going below start level.
I have electronic vehicle battery charger/maintainer I hook up to vehicle battery while not using RV to keep veh battery charged so I can start vehicle.
Just noticed during rehab/repair of my coach that when I have 12v accessory plugged into rear bedroom 12v TV outlet (and coach converter is off or no shore power) that my maintainer is powering up, indicating bedroom outlet is drawing from vehicle batter, perhaps having drained coach battery....seems coach and vehicle batties are tied when ignition is off in vehicle...thought this would not be normal state?
