Why does my Jimmy drain while running?
I have 1997 GMC Jimmy SLS. My question is what could cause the vehicle
to completely drain the battery of the SUV while it's still running. The drain is
so bad that the SUV dies and the battery is drained dead. I have replaced
both the battery and the alternator. I have also had the alternator tested at
multiple locations
and all the locations passed. I'm about to just pull the engine and
transmission and send the electrical nightmare to the junkyard. Can
someone help me I really want to get it running again?
