I need some help. My 86 Vanagon Westy is the Weekender with a dual battery setup. I need to figure out where I need to disconnect the second battery so I can try to get the motor running without burning this thing to the ground. I believe the pos side just bolts to the pos on the first batt but where does the power from the alt come to it? I just want to isolate this circuit temporarily til she's on the road. TIA John
