Pretty certain I have just a headlight wiring issue. I got the diagram and will start chasing it down this weekend. But wanted to throw this out here in case someone has had same issue and can give feedback. Headlight is cutting out intermittently. All other lights are good. Power on and parking lights (running Dominator Duals) are good and constant, same with turn signals, indicator lights, gauge lights, etc. Just no headlight/high beam/highbeam indicator when it decides to cut out.
staying tuned for solution. having the same issue with my dual aztec8's. sorry i'm no help..
Probably just a flaky connector or wires crimped in the connector. Easy to trace and fix.
If you can't solve it, you know where to come.......
Check the wiring etc but dont rule out the bulb itself.
