Headlights not working

Ok, so i recently purchased a 72 Chevy C10 long bed. I'm having problems getting the headlights working. I replaced the headlights and the headlight switch. Still nothing. It doesn't seem to be getting power to the headlights. I've replaced all fuses and relays too. If anyone has had similar problems or any ideas any help will be appreciated. Thanks

Check the plug on the dimmer switch

Re: Headlights not working

Cycle the dimmer switch 20 times and the headlights will most likely start working.

Took a while, but I had the same problem. Tracked it to a bad high-beam switch on the floor.

Re: Headlights not working

Ok, so would it be a bad idea to piggyback my headlights off of my clearance light or turn signal constant? I have power through the firewall, but i lose it in my tangle of chopped up wires. Didnt know if piggybacking could be a fix for now or if it would be too mucb on that wire or not enough power for the headlight. I really appreciate all the help guys.

Re: Headlights not working

Piggybacking is a no-go. The wiring system is designed to carry current for only the items on a specific circuit. That's a great way to overheat things and create a rats nest of wiring later, with short to ground and short to power issues.

A dimmer switch is fairly inexpensive, less than the cost of an oil change these days.

Re: Headlights not working

Rigging your wiring like that is like starting a crack habit. You'll say just this once, and it'll only be temporary. Pretty soon you'll have a spaghetti mess with wires tapping off the battery and all other kinds of nonsense. The guy you have to fix it will charge you double and start with a whole new wiring harness.

Trace the wire out and do it the right way the first time!
