Need help with blinker lights

Bryon · 01-04-2013, 07:14 PM

I have a 1970 mustang. New painless wiring harness. When i put the blinker on both fronts are on also interior indicators. I redid front ground, new blinker switch and flashers.

Thanks

Check and make sure the bulbs are in correctly. Take them out, one at a time and see if that fixes the problem. If so you'll know where to look.

I pulled bulbs allready. I'm no electric wizard but up at blinker switch connection there is power to both fronts which i wouldnt think. I already replaced the china pos switch with one from Drake.

Must be contacts at the switch then as there are 4 separate "outs" to each of the lamps.

Bryon Had the same problem with mine, I can't find my notes but I will give it a shot on memory. Painless wiring harness # 20122 for 69/70 has 3 wires for turn and park lights, disconnect the ground wire believe it's BLK/WHT. Reason being, 69 has a external ground, 70 internal ground the screws holding the housing to the bumper are the ground.I believe that's what I did, and it worked. Good luck don't know how many hrs I spent on that one. If my garage warms up today, I'll take a look at it...It' cold here in WI Zudman
