Harley Davidson Motorcycle Alternator & Charging Parts

Motorcycle engines need electricity to crank the motor and ensure the correct function of all electrical accessories, including the headlights, turn signals, and warning lights on the instrument panel. The charging system plays a crucial role of producing the required amount of energy and storing it in the battery. Besides the battery, the system uses an alternator and a rectifier. While the former generates alternating current, the latter transforms it into direct current, making it suitable for being stored in the battery. Alternators come in different designs, with one-piece and three-piece ones most commonly used in bikes.

One-piece alternators are essentially single blocs containing all the necessary parts to generate electricity; usually, the parts of this type are mounted externally in order to be cooled down by the airflow. In three-piece types, the rotor, stator, and rectifier are stand-alone parts which work together to produce current. If you own a vintage Harley with a kickstarted engine, it is most likely equipped with a DC generator instead of an alternator. Generators produce direct current with no need of rectifier. Regardless of the type being used, our online catalog displays a wide choice of Harley Davidson motorcycle alternator and charging parts at fair prices.
