What Does an Alternator Do?

Car Alternator

If you’re like many Humble drivers, you may be questioning, “What does an alternator do?” The certified service team at Northwest Chrysler Jeep Dodge Ram has the answer! To put it simply, an alternator sends power to the car’s electrical system while the car is running. Did you know that the battery only powers the car to start? The alternator functions as a generator, using the gas engine as its source of energy. For more alternator information, the certified technicians at Northwest Chrysler Jeep Dodge Ram can help with any questions you may have!


What Are the Signs of a Bad Alternator? 

Are you concerned that your alternator may be at the end of its life? If you’re seeing any of these symptoms, make a trip to the Northwest Chrysler Jeep Dodge Ram service center near Sugar Land:

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

Signs of a Failing Alternator vs. Failing Battery

More often than not, drivers will mistake a failing alternator for a failing battery since the symptoms are similar. The best way to get to the cause of the problem is to wait until the vehicle is unable to start and needs a jump. First, go and jump-start the engine, then remove the jumper cables after it starts. You will know if it is your alternator if your RAM, Chrysler, Dodge, Jeep vehicle dies immediately. To have a certified technician take a look, schedule a service appointment at Northwest Chrysler Jeep Dodge Ram near Humble.

How Long Does an Alternator Last?

Alternators last longer than you think! Most of them last between 80,000 and 150,000 miles — or about seven years. However, some factors can cause your alternator to wear out prematurely:

  • Alternator quality
  • Power drain on the alternator
  • Driving conditions
