Default Re: CDI capacitive discharge ignition! what tha!?!

Actually, and this has been proven by disassembly of a magneto coil, there are two seperate windings. The white wire is not a ground but one of the two windings of the coil. The black wire is a ground, the blue the other winding. The rotor/magnet is a two phase input to these coils with an input on every 1/2 crankshaft rotation. Rewinding the magneto coils will have little to no effect on CDI output to the sparkplug. That voltage is determined by the capacitor and triggering circuit in the CDI.
