What Can An Alternator Do for You?

Car Alternator

Interested in learning what an alternator does? Our service team at Big Star Buick GMC can help. The purpose of an alternator is to boost the vehicle’s electrical system while the car is running. It’s well known that the battery is the power source, but the alternator is what’s used to start the car. This is a gas generator that uses a gas engine to gain the energy needed to start the vehicle. Learn more about alternators and more with our team at Big Star Buick GMC near Houston today.

What Are the Signs of a Bad Alternator?

There are quite a few signs to look out for that indicate a failing alternator. If you notice any of these signs on your Channelview commutes, bring your vehicle in for a service appointment at our service center:

  • 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

Evidence of a Failing Alternator vs. Battery

Sometimes it can be difficult to tell the difference between a dying alternator and a failing battery. The easiest way to tell without bringing your vehicle in is by jump starting it. When you start the engine and detach the jumper cables, if you notice nothing happens, then it’s possibly the alternator. Should you want to bring your vehicle in to have one of our professionals take a look, be sure to look over our service specials as well so you can save on the repairs you need.

How Many Years Does an Alternator Last?

Typically, alternators last about seven years. This is without influences that can cause damage including the following circumstances:

  • Alternator quality
  • Driving conditions
