Replaced hi/lo beam, turn signal, horn switches and wiring harness. Have had issue of headlight going off when switching from high to low beam before. Knew that was the problem. Not. Fuse good. bulbs good. Lo beam relay good. Next step is to completely trace wiring harness correct? Any other suggestions before I start that disassembly?

I had a Honda Hawk NTV650. One day the headlights quit working 200 miles from home. A dealer out that way said it was the relay that turns off the headlights during start-up when you press the starter button. The dealer bypassed the relay and all was good. Did it for free because it only took a few minutes to bypass. I bought the tech lunch.
So when you turned the bike on the headlights were on. No longer turned off when you hit the starter. Never caused any issues.
Someone will chime in with the cause and fix though.

The other place that cuts the headlights is the starter button, maybe have a look/clean-up in that area before you get too carried away. When pressed in to start the engine the power is cut to the headlights to preserve battery power for the starter motor. The wires concerned are Black/Red (12v feed) and Blue/white (output to hi/lo switch). You should check whether you have a 12v live at the hi/lo switch, if not take a look at the starter switch.
