Mark VI Lincoln running and parking lights

Post by Fireonthemountain » Thu Mar 24, 2016 4:34 pm

Went to replace a tail light on the Mark VI and the plastic socket crumbled from age, and replaced the socket and bulb. It took me a few tries to get the wiring right on the new socket. Then noticed the one below it was out, and checked the bulb in it, and replaced that bulb. On the other side I decided to check them and one of the plastic sockets also broke and replaced it and the bulb.

Now I have no parking/run lights working, (side, front nor back), but turn and brake lights and headlights are working fine. I noticed also my dash instrument lights seem to go out if I pull the headlight switch out for the park lights or headlights. Checked the fuses and they seem fine.

Got any ideas??

Poor grounds.

Check and double check the ground wire(s) at your tail lamp sockets.

I'll check, but the stop lights and turn signals use the same ground as them, and they work fine. Just the running/park lights are failing to light up now. And the fuse for them is good.
