Functions: The CDI box receives a pulse signal from the stator. It then calculates when the engine needs to fire the spark plug. At the appropriate time, the box sends a pulse to the ignition coil, when then fires the spark plug. (For more information on this process, see Anatomy of an ATV – Ignition Coil.
