What Does an Alternator Do?

As your car ages in Scottsdale, or when you purchase a used vehicle, it’s smart to understand what’s happening under the hood. Our service department is here to help you, but if you want the sense of accomplishment that comes from understanding the mechanics of your Land Rover, it’s easy to learn the basics. What does an alternator do, anyway? 

Your Car Battery’s Charger

An alternator keeps your car’s electrical system working. Turn on the engine, and the alternator goes to work by converting the mechanical energy created by a pulley into a current that charges your car’s battery. Most car alternators can do this for seven to ten years before requiring replacement in Paradise Valley, but that can depend on how well all the moving parts in your car are operating. Keeping your car well maintained can help. 

Signs of a Bad Alternator

There are some signs that can indicate you might be approaching time to replace your alternator. 

  • Dim dashboard lights
  • Service Engine or Check Battery light comes on
  • Unusual noises like grinding, rattling, squealing, or whining.
  • Electrical system issues. Look for problems with features like power windows, the audio system, power seats, lighting, etc. 
  • Car is hesitant to start.
  • Dead car battery, or signs that the car battery is dead but it tests fine. 
  • Smell of burning rubber.

If you experience these symptoms, contact us to make an appointment to have the alternator tested. 

How Much is an Alternator?

How much is an alternator? Alternator prices vary, depending on the car and the type of alternator. New alternators tend to cost from $500 to $1000, while a remanufactured alternator can be $300 to $500. New alternators carry a warranty, as do some remanufactured ones. The Land Rover North Scottsdale service department often runs parts specials that can save you money.
