First off all stators supply AC volts, however some of the older buggies used DC volt stators which you can tell by lights dimming at idle and getting brighter as RPM's rise just like when cars used DC generators years ago. The AC current used in newer vehicles weather cars or buggies require a rectifier to convert AC volts to DC volts. The old AC system used AC volts off the stator for the trigger the new system uses DC volts thus the difference in CDI's used. It does not matter which CDI is used for both will start and run without a battery just like modern day scooters today using DC volt CDI with a kick start. On either AC or DC if the stator is bad you will not start or run. An AC volt system will still run with a bad rectifier since it gets its power off the stator in the form of AC volts where as the DC volt will not run with a bad rectifier. If you recall to check a car alternator while running, if you disconnect the neg. terminal of the battery the engine will die because the rectifier is bad. Due to rectifier being bad the alternator current cannot convert from AC to DC so the ignition will run off the battery until the battery discharges or the negative cable is removed. Bottom line is that either one will run without a battery.
