About 2 months ago my front headlight would not come on while starting my 9'r up. I tried cycling the ignition to no avail. After getting home I removed the headlight and checked the bulb. All was o.k. Voltage was hitting the switch but not the headlight. Whilst examining the switch the light mysteriously came on. The next night it did the same thing. This time however I accidentally hit the horn and the light came back on. WEIRD. Every time since then the headlight does not come on, all I have to do is tap the horn and it comes on.
The only mods I have made electrically is adding the pc3.
Could there be an issue from when I originally wired the pc3 into the harness and the one connection that may have started to corrode?
Go by Radio Shack and buy a can of spray contact cleaner. Pop that baby open and spray it real good. Cycle the switches a few times to work it in real good. Close her up and see if that doesn't help. I've had bike switches get oxidized on me in the past and do some funky things.
