I lost spark to all four coils. I found a wire under the flywheel chaffed and shorted out against the under side of the flywheel. There is 12vdc on this wire.. Not sure what to check, maybe a fuse??, rectifier, stator.... Any suggestion out there??? Prior to this electrical short,the motor was running, but very rough.. Now I know why... <br /><br />Thanks.. This is a great web site...
