What Does an Alternator Do?
The alternator is a major part of your vehicle’s electrical charging system. It turns mechanical energy from the engine into electrical energy, providing power to your lights, radio, battery, and the rest of the electrical system.
If your alternator is not functioning properly, your car may not be getting all the electrical power it needs, leading to dim or flickering lights, or a drained battery that is unable to start your car the next time you need it to. Eventually your vehicle may be completely unable to run.
The alternator plays a crucial role in your vehicle’s operation. If you notice any of these symptoms in your vehicle, you and your passengers may be at risk of being stranded by a car that no longer runs.
