The item "CDI unit Delta, Alpha" is a CDI unit for Alpha and Delta mopeds. The CDI unit controls the ignition spark: it generates a pulse for the coil on the signal from the sensor.
Replacement is needed when there is no spark or the ignition runs unstably, after first checking the coil and the sensor. Manufacturer: TMMP. If the old part has a marking, compare it with the name in the product listing.
