What Does an Alternator Do?

Car Alternator
Have you ever wondered, “what does an alternator do?” If so, you’re certainly not alone. Lots of car owners from Kansas City to Overland Park can agree that although they know of their car’s essential components, they’re left in the dark when it comes to understanding what they actually do. Put simply, the alternator delivers power to your car’s electrical system when your car is running –– think of it as a generator. Learn more about your car’s alternator with our service center!

How to Tell if Your Alternator is Failing

What does an alternator do when it’s failing? There are several warning signs you might experience when the alternator is going bad, including:

  • The headlights are losing brightness
  • Devices won’t charge when plugged in
  • You can’t start the car at all
  • The battery warning light pops up on your dash
  • You can smell an odor like burning rubber under the hood
  • If the vehicle starts, there’s a whining or screeching noise soon after

Failing Alternator vs. Failing Battery: Know the Difference

All too frequently, Shawnee Mission drivers think their failing alternator is a bad battery. The most reliable way to differentiate between the two is to wait until your car needs a jump-start. Proceed with jump-starting it and remove the cables after it starts successfully. If it proceeds to die straight after, you’ll know that it’s an issue with the alternator and not the battery. Of course, it’s always good to have a trusted technician take a look, too.

What is the Lifespan of an Alternator?

Typically, alternators are good for about 80,000 to 150,000 miles or approximately seven years. Certain factors may cause the alternator to die prematurely, such as:

  • The alternator was lesser-quality to begin with
  • Adverse driving conditions
  • Something is draining power from the alternator
