Default Re: electrical problems installing digital volt guage

If you want it to be switched on and off with the key leave the positive hooked up at the key switch and run a negative wire back to the battery pack negative. Remember that there should not be any wires hooked to the frame, all grounds need to go directly to the batteries.
