The alternator freewheel clutch in a car serves a crucial role in the electrical system. It is responsible for connecting and disconnecting the alternator from the engine's rotation. When the engine is running, the alternator freewheel clutch engages, allowing the engine's energy to be transferred to the alternator. This enables the alternator to generate electricity and charge the car's battery. However, when the engine is not running or is idling, the alternator freewheel clutch disengages. This prevents the alternator from causing any drag on the engine, ensuring efficient fuel consumption and reducing wear and tear on the components.
