I'm drawing a blank here. The headlight elements look good and the fuse looks whole. An idea why I don't have headlights when the bike is running? Tail light and brake lights work fine. I hate electrical issues. :wtf:
 
Check the light with it just hooked to the battery. If it works it may be a ground or the light relay may be bad. Could also be a bad ground. Use a meter to check the fuses and if they are the old glass ones make sure they are making a good connection, or upgrade to blade style.
 
Power to the fuse box is good and there's power on both sides of the fuse. Hooked the light to the battery and it works, too. No power to the dimmer switch, though, when the bike is running. What am I missing?
