I was trying to figure out the wiring mess on some old Harley. Supposedly it quit working after swapping the lights and handle bar, and the guy clamped the throttle and brake onto the handle bar over the wires without running them through the bar shorting all those wires out. I'm not quite sure what I'm doing as far as testing things with the multimeter, though I know how to use one. I almost got the 7 wires on the right handlebar repaired. Not sure if the coil has power, but I don't think the ignition selector switch has power.
