So I just got my 82 150, and the headlights and front blinkers dont work. Ive traced the wires, and they look good, and the fuse box AND fuse is good. Is it a bad ground? The inside switch? I just need to be headed in the right direction!

 

when you turn the headlights on is there power at the yellow wire that goes to the dimmer switch on the floor?

 

Not exactly sure, how would I figure out?

 

you could use a voltage meter or test light. just have to unplug the dimmer switch.

 

will do, if it doesnt work Ill come back!
