ELECTRICAL HELP!!!!!
I wired my (2 )12volt batteries in series. I also wired in my on/off switch and the charging lugs. When I take my test light and clamp the clip to the negative side of the battery and touch any metal surfaces of the car ie; the roll cage, tin on the tubs and the body of the car, the test light lights up. In my series of batteries, the only place Iv'e gone to ground is on one of the roll bars. I have unhooked about everything that is not nessary to staring and running the car. All metal parts still have a charge. My question is do I need more grounds? From engine to frame, frame to body? I just can't figure out why the metal parts of the car has 12.65 volts. Please HHHEEEELLLPPP.................Rob...............Th anks
