The alternator is in charge of providing electrical power to various systems throughout your car. Understanding how the alternator works and how it varies from the battery is helpful for every vehicle owner to understand. Keep reading to learn more about the car’s alternator.
How Does an Alternator Work?
As mentioned, the alternator is responsible for providing electrical power to different vehicle parts. Most people may confuse it with the battery, but they are two separate things. Once the battery starts up the engine, it is the alternator that takes over to provide a continuous supply of energy to keep your car running. In other words, the alternator recharges the car battery.
The alternator transforms mechanical energy into electrical energy. The crankshaft and the serpentine belt wrap around the alternator to drive the alternator. Electricity is produced when the rotor spins. And the electrical power gets dispatched to the voltage regulator that distributes electricity to your car’s many electronic accessories, like the radio, power seating, headlights, and windshield wipers.
What Are the Warning Signs of a Faulty Alternator?
Most alternators are built to last a long time, sometimes to the end of the vehicle’s life. However, there are parts inside the alternator that can wear out. Whenever this happens, you should seek alternator repairs. Here are several warning signs a failing alternator may display:
- Weak Battery - If your battery has constant issues or dies, it could be caused by a failing alternator that is unable to recharge the battery.
- Dimming Lights - Dim or flickering headlamps is a sign of alternator failure. When the alternator receives inconsistent voltage, you may experience this inconvenience.
- Unusual Sounds - The alternator might whine or growl as the belt around it gets shifted or misaligned. You should always have any weird noises checked out by an auto professional.
- Starting Problems - If you hear clicking noises before your engine starts up, it can be caused by a damaged alternator.
