What Does an Alternator Do?

The alternator is a vital part in your vehicle that converts your engine’s mechanical energy into an electrical current to power the charging system in your car. It lives under the hood, and if it’s not working as it should, the visible problems could range from dim dashboard lights to a full engine stall. For that reason, your alternator should be checked often to ensure that your vehicle is running safely and efficiently on the roads near Edgewater.

Here at Land Rover Annapolis, we are happy to service your alternator and answer any additional questions you may have about this car important part.

How Does the Alternator Work?

When your car battery dies, people may suggest you let it run for a while after it’s jumped so it can charge up a bit. The alternator is the component that makes this charge possible. While your engine runs, the alternator charges your car battery by converting mechanical energy generated by a pulley system into an electrical current.

The alternator receives this mechanical energy from the engine via the serpentine belt, another very important part of this system. As this belt runs around the system, it delivers energy to the alternator, which then converts that to electrical energy to charge your battery.

How Much is an Alternator?

Depending on where you source the new alternator, this price can range. Remanufactured alternators span from $300 to $500 and may include a warranty of a few years. New ones can cost $500 to $1,000 but often carry a limited lifetime warranty. Our parts department can help you source a genuine OEM part for your Land Rover’s year, model, and trim. We’ll also install it for you, so you can be confident back running properly on those Crofton and Severna Park roads!
