Default Help Request- Headlight and Passing Lamps Not Working

08 Road King. I checked the fuse, its good. All other lights are working. Is there a notorious wire known for breaking? I'm horrible with chasing electrical problems but I have a multimeter.

Looks like it's the yellow wire maybe. I jumped a wire from the fuse block to the yellow wire terminal spade on the headlamp and that lights them all up. Is there a location where this wire commonly breaks?

I'm like you.... not real good with electrics, so I can't help much. But a worthwhile tool to have is a service manual. it would have wiring diagrams that will help. Where is the wire you tagged? what is between that source and the lights? that will be where your problem is?? Pinched wires? Bad switch? It would help if you could isolate that circuit and see what is there and see where on the bike.
Good Luck!!

I know you said the fuse was good but check to see you have current at those fuses too.

I had an issue earlier this week with my headlight. It's been an issue on and off for weeks now. Checked for current at fuse block for headlight and lights fuse with my 12 volt tester and although fuses were good I had no current there. I checked the headlight relay and I had one prong that seemed kind of dirty. Cleaned it up and all is well now.

Thanks, I did check the service manual but couldn't fing too much except the schematic.
Good news is they are working again, bad news is I don't really know why.
I'm the proud new owner of an electrical gremlin.

Munkee I did check the fuse holder and had power there. I tugged wires, played with the contacts behind the headlamp, etc. while looking for the passing lamps to go on because the headlamp was disconnected. Then I realized they weren't going to go on because my high beam switch was on. I flipped to low beam and they came on, and of course the headlight works now also.
So I'm not sure at what point of jiggling wires fixed it.

They work as they should now, but when jiggling wires the headlamp was disconnected and high beams on so of course the passing lamps didn't illuminate until I flipped the switch to low. In other words I don't know what I did to fix it.
