It knocked off while my grandson was riding, and wont make fire to the plug now. I changed the coil, didnt help so I put the old one back on. I have taken the switches off the handle bar and by passed the brake light switch, and the tether. Nothing. I checked the ground on the coil, it was good. I took the kill wire, black wire, out of the CDI, still nothing. I have done nothing to the stator.

Does anyone have any ideas? Thanks in advance for any help. I'm an old PawPaw trying to make my grandson happy.
