Stew there is no easy answer to your question without knowing more about your current setup.
Stew CDI's basically come in 2 versions, AC and DC, and this relates to their power supply. AC useseither a AC output magneto or alternatorand DC is usually a combination of a battery and/or a AC magneto, AC alternator, or DC generator. On my Ski-Doo the Rotax engine is a AC magneto (lighting coil and large cap)and the CDI converts this to regulated DC for the CDI ignition. On my Honda XL250 it uses a battery and a regulated AC alternator, the battery is used to provide power to the CDI for starting and once rpm comes up the alterantor provides power. There are many different designs and ways to power a CDI, for example, some use the higher voltage of the AC magneto to provide the stepup voltage (about 90 - 250volts AC)to the ignition coil. These use a thyristor, SCR, or MOSFET to discharge the cap andtrigger the coil. In this setup no oscillator for voltage stepup is required but, you have to kick the motor over quite fast to start and most people I know replaced or modifiedthis system with a battery or very large capacitor for starting power. They also had to add a very large (power) zener, resistorand arectifier to control charging.

As John pointed out about or system is that it requires 6-12volts to the 5 volt regulator which in turnsupplies power to the Timer and HV boards. How go get 6 -12 volts to 5 volt regulator is up to you. Right now you can make your own, ask Gompy if he has something that will work or wait until someone else offers a built system.
