Car Alternator


There are many vital components in your vehicle that allow it to perform smoothly on Evergreen roads. One part that plays an important role in your vehicle’s functions is the alternator. But, what does an alternator do? Your alternator can technically play a role in many different components of your vehicle.

However, its main job is to send power to your vehicle’s electrical system. The alternator essentially functions as a generator and its main source of power comes from the engine. Today, the service experts from Lee Motor Company will help you answer the following questions regarding your alternator:

  • What does an alternator do?
  • How do you know if your alternator is going bad?
  • How much is an alternator?
  • How long does an alternator last?

How Do You Know if Your Alternator Is Going Bad?

The symptoms of a bad battery can sometimes be confused with a failing alternator. If your vehicle doesn’t start, give it a jump start. After your vehicle has been successfully jump-started, remove the jumper cables. If your vehicle immediately dies, it’s likely that you have a bad alternator.

However, before your vehicle leaves you stranded in Brewton, there are some signs you can look out for to catch a failing alternator early on. If you notice any of these signs, it may be time to schedule a service appointment for an alternator replacement:

  • Illuminated battery warning light
  • Dim interior/exterior lights
  • Smell of burning rubber coming from your hood
  • Malfunctioning electrical components
  • Failure to start
  • Screeching sound after vehicle starts

How Much Is an Alternator & How Long Does It Last?

So, how much is an alternator? Truthfully, the cost of an alternator can vary widely. Different makes and models can change the cost of an alternator so we suggest you give our parts center a visit if you’re interested in learning more specifics.
