An alternator is the component that generates electrical power while the engine runs and charges the battery.

The engine drives it by belt, and it converts that rotation into electrical current to run the vehicle's systems and keep the battery charged, while a regulator holds the voltage steady.

The alternator is mounted on the engine and driven by a belt. The correct alternator matches the engine, output rating, and mounting; charging faults are best diagnosed by a qualified technician.
