CDI unit for Active mopeds. The CDI unit controls the ignition system: it stores energy and delivers it to the coil at the right moment, creating the spark.
When it fails, the spark disappears and the engine will not start or runs with misfires. Before replacing the unit, check the coil, the sensor, the ground and the connectors, and note that CDI failure is often linked to a faulty voltage regulator.
Country of origin: China. If you have trouble choosing, call the store and we will check against your model and year.
