I'm curious about desulfating my house batteries. I have four 6-volt batteries. To hook up my desulfating charger, should I remove the cables and isolate it from the coach charge system? I was thinkin...
On many/most coaches, the salesman switch does NOT disconnect all house electronics. Things like refrigerator, propane detector, etc are often wired such that they work with salesman switch off. Check and verify, do not assume.
Safest to disconnect the ground/negative cable at the battery.
