Bad run switch/start button? No ground?
I'm near the end of my rebuild and I've put the wiring harness in, went to turn the engine over (no fuel, but wanted to make sure it did) and nothing. I've gone back and forth and done some testing. I've narrowed the issue down to the run switch and/or start button. I think the issue is limited to the start button, but I'm not sure.
First, I unplugged the whole start/run assembly from the main harness. Then, I shorted the two pins that the run switch appears to be wired into (red and yellow/red) and then shorted the black/red wire to the frame ground. The starter turned over!
I left the run switch wires jumped and plugged the harness back in and tried the start button, but nothing. Took apart the run switch and start button, checked the connections and cleaned all the contacts with a Dremel with a wire brush attachment - put it all back together and nothing.
I'm at a loss at the moment, any ideas? I should note I replaced my handlebars with new ones which are painted black, and also painted the handlebar clamp black - I checked with a multimeter and the handlebars are not showing up as ground. Do I need to scrape away some paint so the handlebars are considered ground?
