Default 2008 Flhtcu Headlight not working
2008 Electraglide Classic.
Headlight is not working. Both spots work, fuse has been changed. I also tried an old headlight to see if it was my daymaker.
what would i put my multimeter on and what should it read at the HL to see if i am getting power to it? Is there a relay for the headlight?

thanks for the help.

Did the other headlight work when you plugged it in? Had the same problem with my wife’s bike and turned out the LED headlight went bad, bought a new one and all good since.

Look for 12vdc on the plug when the head lights are on. Attach ground to the frame, and test the plug.

I tested what i think is the correct plug. A couple of the slots lit up my test light.
Should they all light up?
