I had this problem once before but I never posted it. I own a 1991 SN SJ with a b-pipe and msd enhancer and more upgrades. When I turn on my bilge pump, I am getting a small shock when I touch the throttle. I once had this problem before I had the pump, where I was just getting shocked by touching the throttle. I am 90% sure it is the ground wire in the E-box. Thoughts? That was my problem last time. OH, I also get shocked just by sitting in the tray. Not fun. LOL. Wanted opinion before I unscrew the E-box.
