Paul prinzo Posted November 4, 2017 Share Posted November 4, 2017 Restoring a 86 DM 800, installed the cab after paint and now have issues with lights. All the lights and blinker switch are new.Blinkers work until I turn the ignition on, roof lights are dim.I think it’s a ground issue. I have a good ground to the terminal strips on the firewall but I’m thinking because everything was disassembled for paint, I don’t have a good ground to the dash? Should I run another ground to the dash? Where should it go? Quote Link to comment https://www.bigmacktrucks.com/topic/51600-bad-ground/ Share on other sites More sharing options...
j hancock Posted November 4, 2017 Share Posted November 4, 2017 Ahhhh..... electrical issues. Adding another ground never hurts. I have found GM A bodies were always notorious for needing another ground to the dash. I have a length of wire with alligator clips for testing things out. So i would use it to make a temporary ground and see what that gets you. You may have already double or triple checked your work but I was chasing a problem and had connected the dimmer switch on a B incorrectly and it was back feeding the harness causing gremlins.

Paul prinzo Posted November 4, 2017 Author Share Posted November 4, 2017 My dimmer was a plug, but my headlights were individual wires, could be my headlight switch wires Quote Link to comment https://www.bigmacktrucks.com/topic/51600-bad-ground/#findComment-384316 Share on other sites More sharing options...
