What Does an Alternator Do?
The alternator in a vehicle works to keep the car alive while the engine is running. It supplies a direct current to most of the electrical systems in the car, including the headlights,, dashboard, radio, and more. It also works to charge the car battery while the engine is running by converting mechanical energy into electricity.
You can tell if an alternator is malfunctioning or beginning to wear out from some easy-to-notice symptoms, such as dim headlights, a dead battery, trouble starting, frequent stalling, constant low battery, or a wide array of similar electrical problems.
An alternator replacement cost depends on the manufacturer and model of the car.
