What Does an Alternator Do?

Alternators are responsible for sending power to your car’s electrical system while the engine is running. The battery may get the car started, but it’s the alternator acts as a generator, harnessing the engine’s energy to keep the car going. Learn some alternator tips and tricks, and discover when your alternator may need service.

Engine Warning Lights

Common Alternator Problems

Because your alternator’s health is so vital to your car’s performance, it’s important to be aware of problematic symptoms such as:

  • Battery warning light appearing on the dashboard
  • Dim headlights or interior lights
  • Burning rubber smell under the hood
  • Devices not charging
  • Whining or screeching sound after the vehicle has started
  • Unable to start

If you notice any of the above, schedule service at your local Honda dealership in Roseville right away. Ignoring noticeable issues could lead to bigger, more expensive repairs down the line.


Failing Alternator vs. Failing Battery

A faulty alternator is commonly confused with a failing battery, since both are responsible for different aspects of engine power. A surefire way to determine whether your battery or alternator needs repair is to jump start the engine, and then remove the jumper cables right away. If your car dies immediately after, that means the alternator can’t keep the power going and needs to be fixed.

How Long Does an Alternator Last?

Your alternator should last you anywhere from 80,000 to 150,000 miles, or about seven years. This is merely an estimate though, as component quality, driving conditions in St. Clair Shores, and the power drain on the alternator could cause yours to wear out faster.


How Much Does it Cost to Replace an Alternator?

Every car is different, so a replacement alternator can vary in cost. If you’re worried yours is in need of repair, have a certified technician take a look and give you an estimate. At Jeffrey Honda, we offer Sterling Heights-area customers a variety of service specials to help make repairs more affordable and keep everyone driving safely.
