xmastree Posted June 4, 2007 Share Posted June 4, 2007 The three white wires will be the three phase AC from the generator. They go to the reg/rec which charges the battery. Nothing to do with the ignition. The other two will be from the ignition pickup coil, and should connect to the CDI to trigger the spark. Probably...
