Hello everyone! I just signed up and been looking through threads but couldn't find exactly what I am looking for. I have a 76 truck project vehicle. Problem; My parking lights work. taillights work. Brake lights work. Hazards work. HEADLIGHTS DO NOT WORK. BLINKERS DO NOT WORK. HEEEELLLLPPP

 

Clean all your grounds. Check your thermal link for the headlights. It should be attached to the (+) battery terminal.
Most times it’s poor grounds on these old trucks.

 

Thanks Fred, will do! Question though, is there a headlight RELAY? If so, where is it at?
