Default Re: CDI inside

The ignition box on an HT is not really CDI which would require sensor inputs and 12 supply. I cracked a dead one open couple years ago and it appears to be a simple coil/cap combo with diode to converve back EMF. Very simple and reliable but not as efficient as real ones with timing advance etc..

IMO it's a mistake to use the white wire for anything but the ignition. They need all the help they can get, I am very curious about the add-on magneto coil mentioned previously.
