No Sparks ??!?!? Vespa PX PK :

Check First the CDI and the Stator Plate.

This Video is a How to uide for Testing the CDI and as well a Short Intro about the Function of the CDI.



How It Works:
Energy Generation: When the engine turns, the stator (alternator) generates alternating current (AC), which is stored in the CDI unit.

Charging the Capacitor: The generated AC power charges an internal capacitor inside the CDI unit.

Ignition Pulse: A signal from the pick-up sensor determines the exact moment when the capacitor releases its stored energy to the ignition coil.

Spark Generation: This sudden discharge creates a high-voltage pulse, which is sent to the spark plug, igniting the fuel-air mixture.

This precise timing ensures efficient combustion and optimal engine performance.

Connections of the CDI Unit:
The electronic unit has four connections:

White (BIANCO): Ground connection.
Red (ROSSO): Connection to the pick-up sensor.
Green (VERDE): Power input from the stator (alternator).
Green (VERDE): Kill switch for engine shutdown.
