Alternators

While you may not realize it, your vehicle utilizes a lot of electricity to keep it powered and running properly. The alternator is in control of a range of electrical components, both interior and exterior, so it's very important that you replace the alternator if problems start to occur. It takes a lot of power to start your engine, and while your battery is something that has power, it wouldn't have enough to start the engine and run all of the other electronic components under the hood of your vehicle. The alternator helps to charge the battery while the vehicle is running. It does this by turning mechanical energy to electrical current. Parts of the alternator will wear out over time. You might start to notice symptoms of wear and tear like dimming lights. Flickering or dim lights are obvious signs of something being wrong with the alternator. Electrical systems in your vehicle like power windows or your radio might start to fail or struggle to perform. You could also have an alternator warning light in your car that comes on. Shop with Audi Parts Store today to find the highest quality OEM alternators available for your make and model.
