Hello.


I built my Harley from the frame up. I used a Thunder Heart Micro Wiring harness.


My problem is, that when I hit the Hi Beam switch, all my lights go out (head/tail, and all turn signals).


However, as long as I keep it on the Low Beam, everything works.


Before I start tearing stuff apart, I'd like to have a few ideas on what might be causing this issue. Your comments are greatly appreciated.


I have a 12-volt system (no ECM computer).


Thanks!
