1976 Vett.

I have replaced all my turn signal and side marker lights with LED bulbs as well as the turn signal flasher unit behind passenger dash pad and emergency flasher unit mounted directly to the fuse box. All lights work great with exception of the front left. I get parking lights but no flash for turning or emergency. I have researched the subject here and most recommendations indicate a bad ground.

My question:
Where is the physical ground located in the car?? I have a whole car wiring diagram which indicates several black wires converging at a common location. Where is it??

Thanks in advance :thumbs :

IIRC, the ground comes off the light and attaches to the core support.

The primary ground is where the negative battery cable attaches to the frame. That makes any metal that is attached directly to the frame a ground source. Clean the ground for the light in question and that should solve your problem. Good luck

Would that be on the left side of the core support??

I think you guys are talking about this ground:

On a 71 drivers side of radiator support.





Also an additional earth near horns on headlight support bar.
