I was riding the bike all weekend and there were no problems with the lighting. This morning I went to start it and found headlight dark. I thought it was a bad bulb so I swapped it with a good spare, still dark. Checked and replaced head light fuse, still dark. Now I am suspecting a short somewhere. I also noticed that the high beam indicator light is now also lit up. If I leave the bulb unplugged from the harness then the high beam indicator light is not lit up. So I suspect I have a short somewhere. Cycling the high/low switch makes no change to either the headlight or the indicator light.

just looking for pointers about how to troubleshoot and key points to try.

Thanks

Thank you very much, I will do it this weekend.

Yes I proved I have lost the ground. I made short sections of wire between the socket and the bulb for each of the white and blue wires and a longer section for the green wire. All works well when I ground the headlight to bike. Now to chase why the headlight ground is poor.

Thank you. I have both the Clymers manual and the FSM. In the Clymers manual on their version of the wiring diagram, the legend refers to both a "ground" and a "frame ground". What is the difference? The FSM only shows a ground. In the diagram I counted 7 ground symbols. Does that mean there are 7 points somehow connected directly to the steel frame of the bike.?
