Hi new to the forum here. I have a 72 Supreme and for some reason my headlights dont work. The side markers and brake lights come on when i pull the headlight switch all the way out. My highbeam indicator light on the dash is stuck on. Pressing the dimmer switch doesnt do anything. I have 12v. at the blue wire with the dimmer switch out and when i plug it in i get no volts. I bout a new dimmer switch that looks a little different out of the box but conections are the same, installed it and still nothing blue light comes on and still no lights. I check all fuses at fuse pannel under the dash and all seem good....Any advice would be great thanks!!
