The alternator is a form of electrical generator in which a magnetized field called a rotor revolves around a set of stationary coils called a stator assembly. As the rotor revolves, alternating current is induced in the stator coils. The current is then rectified to direct current and is used to operate the electrical systems on the motorcycle and to keep the battery charged. The rotor is permanently magnetized.

Rotor Testing

The rotor is permanently magnetized and cannot be tested except by replacing it with a known good one. The rotor can lose magnetism from old age or a sharp hit. If defective, the rotor must be replaced; it cannot be re-magnetized.
