Frequently Asked Questions
What does the Stator do?
The stator is responsible for generating AC voltage that is used to charge the battery and power the CDI unit.
What is the function of the Regulator?
The regulator ensures that the voltage output of the stator is regulated and not too high, which can damage the battery and other electrical components.
What is the CDI Unit?
The CDI (Capacitor Discharge Ignition) unit is responsible for providing the spark to the spark plug that ignites the fuel in the engine. It also controls the timing of the spark.
What is the function of the Coils?
The coils amplify the voltage from the CDI unit and then provide it to the spark plug to generate a spark.
What is the Fuse Box for?
The fuse box contains fuses that protect the electrical system from overloading and short circuits.
