I have a 1969 Camaro that I changed over to all LED bulbs. I changed to a no-load flasher module, but the front turn signal don't work if the running lights and/or headlights are on. If turned off then they work. I'm puzzled...and it won't pass inspection. Any ideas? Thanks! James

 

Install a P/N 552 flasher.
Alternator is working?

 

Jsharp,

Most likely, you have corrosion in the light fixture itself, or a bad ground there. Check the grounding by clipping on a temporary ground wire, and see if that fixes things. If the fixture is corroded inside, you may be able to get a pre-wired new fixture from NAPA (or others). If the grounding is shaky, run a new dedicated ground wire from a solid ground point to the fixture, right on top of the existing ground wire. Keep us posted.

 

thanks! will take a look

 

thanks for the reply. alternator is good. I will try a 552 flasher and new incandescent bulbs.

 

Ended up being the wiring. Had installed aftermarket turn signals and had to switch the polarity and now they work!
