Default No high beams. Everything else works?!

Hi all!

I have a 2004 electra glide I have owned it for 2 years and since I bought it the high beams have not worked.

Last summer I replaced the headlight and spot lights with the sunpie "daymakers" hoping it would fix the issue but it didnt.

Jusy wondering what could cause just the high beams to not work correctly.

As of today I have traced all wires and found no issues. Also have done some continuity tests to make sure there were no breaks in any of the wires.

Thanks in advance!

Do you have 12 v output at the white wire in the locations marked in the images below?

Remove the headlamp from the shell (leave the connector plugged onto the lamp), check the voltage of the white wire inside the connector (hi beam switched on of course).

What is the voltage?

Back to you...

Have you checked for power at the hi/lo beam switch on the handle bar?

Hey all. Thanks for the reply! So I checked the wire behind the lamp with my meter and it is getting 12v. The dash also indicates the high beams are on.

Also forgot to mention when I turn on the brights I have zero lights at all.

Sounds like there's no power for the high beam inside the lamp fitting.
The passing lights should work in low beam mode only.

Passing lights do work in low beam mode. I did notice that the fuse/relay is oversized. It has a 20 in it.

20 amp all the way to the left.

Sounds like you have a grounding issue with you light wiring some where if you have 12V to the bulbs.

I’m confused. Put your meter between the black wire and the yellow wire, and turn on only the low beam, and you should get 12v or a bit more. Then check between the white and black, still only in low beam, and you should get 0. Then without moving the meter turn On the high beams and you should get 12 volts.

if this all correct you got a bad light.

Otherwise, do it and report back..
