What is an alternator?

The alternator is a component in your vehicle that helps charge the battery. When you use items in your vehicle like the lights or charge you cell phone through a port it draws electricity from the battery. The alternator is what keeps the battery charged up when it’s depleted of electricity.

How do I know that it needs to be replaced?

Usually when it’s time to replace the alternator your lights within the car will dim. In some vehicles there is an additional battery light that comes on which could indicate an issue. If your car does not start, it could also be the alternator.

Why is it important?

As stated before, if your battery cannot recharge itself due to a faulty alternator then it will eventually run out of juice. This will lead to bad performance in the vehicle’s electrical components or your vehicle will eventually not start.
