What Does an Alternator Do?

Alternator of A Car

Part of the joy of driving an Alfa Romeo Giulia on the streets of San Leandro is feeling its electricity and power. But what happens when that electricity dims? It could be your alternator. If you’re wondering what does an alternator do, McKevitt Alfa Romeo of Berkeley is here to help. 

How Does an Alternator Work?

The alternator keeps your car’s electrical system working. The alternator converts the engine’s mechanical energy into a current that charges the battery. Most car alternators can do this for seven to ten years before requiring replacement in Walnut Creek, but that can depend on how well all the moving parts in your car are operating. Keeping your car well-maintained can help. Even if your Alfa Romeo is only driven occasionally, you need to keep the engine well-maintained so that parts like the alternator don’t deteriorate from lack of use. 

Signs of a Bad Alternator

Unfortunately, drivers have been left stranded when alternators have died. Most of the time, your alternator will let you know it’s time to be replaced, if you know how to recognize the signs of a bad alternator. They include: 

  • 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 our service department to make an appointment to have the alternator tested. 

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 McKevitt Alfa Romeo of Berkeley service department often runs parts specials that can save you money.
