So I'm building a 3 wheeler and it uses a proprietary dc powered CDI unit. I am thinking about running one of the generic 5 pin cdi's off a 120v inverter to power them, since the stator coil only generates 2.5 volts while trying to start, which is not enough to fire the CDI. I'd wire the CDI's power in to the live wire on the inverter, and ground the inverter's ground pin and cdi's ground wire to the frame. I'm thinking its a good idea to put a resistor or low wattage light bulb between the inverter and the CDI. The CDI will still get its trigger pulse from the trigger coil near the stator.
