Hello, I am working on a friends Dyna, the low beam is not working. Replaced the bulb, still doesn't work. The bike has apes that have internal wiring, I assume the switches were on the bars when she bought them. There is power for the low beams off the switch. The harness from the switch AND the headlight bucket appear to go back towards the battery area, through the frame. Can anyone tell me where the terminations are that join the switch and the headlight? I've taken the tank off (not necessary), if I can get info on the terminations, it may save me more time finding them. I assume there is not a relay in the headlight circuit.
Thanks

Mike

 

on my '03 wide glide they're in the backbone just inside under the tank. I had to pull the loop of wire up from in front of the rear tire on the bottom and pull the harness through towards the front of the bike in order to get to my plugs when I changed bars and wired them internally. Its a 2 man job.

 

So Mike, you're saying that to check the plugs, I need to pull the harness forward and pull the plugs out of the backbone? Thanks for your help!

 

Since you have Apes its possible the harness has already been pulled forward enough. I'd try working it forward from behind the plug in the frame just ahead of the tank. If you can't seem to work it forward enough then check the loop at the back.
