I have a 69 olds I'm restoring.. The headlights are really giving me fits? They just won't come on and I don't see a fuse or any other issues.. Any thoughts?

 

Are we to assume that all other lights come on with switch? If so do you have voltage at the plugs for the headlamps? Could be a dimmer switch?

I second 1970cs here. We need more info. Do any other lights come on when you pull the headlight switch? If not, you might suspect the headlight switch itself as the problem. While they're kind of pain to get at and remove, they're cheap and readily available.

The dimmer switch is also another possible source of the problem as all power for the headlights goes through it. Again, they're cheap and readily available, and, unlike the headlight switch, are easy to get at and replace. If yours is suspect at all, I'd just replace it so you can eliminate it as the problem.

 

There is no fuse. There is a self-resetting circuit breaker built into the headlight switch. This is rarely the problem, however. More likely is a bad dimmer switch. Pull the three wire connector off the dimmer switch. With the headlight switch on, check for +12V at the blue wire in the connector. If you get power, the switch is good, if not, the switch (or associated wiring) is bad. Assuming you get power, now jumper the blue wire to the tan one. The low beams should come on. Jumper the blue wire to the green one and the high beams should come on. If this works, replace the dimmer switch. If not, the problem is somewhere in the wiring from there to the headlights. It could be a ground problem at the core support, but it is unlikely that the grounds on both sides would be bad at the same time. Also verify that the firewall connector is properly mated.

 

 

Thanks all.. It was the dimmer switch... Working good now.. I should have checked here first before spending 2 hours going through all the wires lol
