ok, i need help with lights in my 65. the left side turning signal and the left side rear light is out. also the right side headlight goes dim when switched on.
where do i start checking for short or wire problems. the bulbs looked good and all, but im gonna actually check em tomorrow
first check your grounds as they are the biggest cause of electrical problems. after that, start at the load and trace the wires backwards checking for problems.
It's been 20 something years since I had the same problem in my 67, All I could tell you now is remove the headlight and trace the wires back to the ground point. Should be behind the light somewhere.
