no lights!!
Hey guys, ive been off the forum for a few years now because I sold my ford and now i own one again! 
its a 1979 Ford F100 390 4spd, my first dentside! anyways, im not getting any lights, so first thing i did was replace the switch, worked great for about 2 minutes, then I lost all lights again, the only light i can seem to get is the right head light? I am stumped. =\

Make sure your headlight switch is plugged in right. That happened to me when i replaced mine. It popped and started smoking. I took the plug off, turned it around and plugged it back in. Works fine now. I also had to rewire everything because of corroded wires and bad grounds. Also check ur plug ins that should be mounted on the drivers fender.

It goes to a relay near the starter solenoid.

There is a bundle of wires coming out of your firewall. If i remember right there is 3 plugs. They are only about a 1 1/2 sqaure or so. One side of the each plug goes into thecab and the other ends branch off to your lights. Pull them apart , clean them out and put some dielectric grease in them. Also take a test light to each light and see if you are getting power. When i got my truck EVERY light bulb in it was black. I had alot of work to do on mine just to get lights.
