    some CDIs connect through a coil to spark plug - these are rare

    most kits only have a coil on the stator of the magneto

    the stator coil/magneto produces an AC voltage which powers the CDI. at the right time the CDI dumps a spike of voltage into the high voltage coil which amplifies it to produce a spike of thousands of volts going to the spark plug.

    the CDI converts the AC voltage to DC
