Dead Battery or Alternator?

Posted April 25, 2017

When your car won’t start, the battery is often the most likely culprit. Usual suspects include leaving the lights on overnight or an aging, corroded battery. But the alternator could also be the reason your battery has died.

The alternator is responsible for powering the electrical components in your vehicle and for recharging the car battery. When the engine is running, the alternator manages the flow of electricity powering electronics and charging the battery. Maintaining proper charge in the battery is critical for the performance of your vehicle.

How do you know if the alternator is failing?

If you suspect a problem with your vehicle, the best thing to do is bring it into Book’s Automotive Service for an inspection. Our experienced technicians can inspect the battery, alternator, and electrical systems to determine the cause of the problem.

One cause may be the alternator belt. A loose or worn belt can affect the alternator’s performance. Electrical failures, dead or weak batteries, dim headlights, or engine stalling are signs of an issue with the alternator.

Watch for key warning signs of an issue with your alternator or belt. These include:

  • Squealing, whining, or grinding sounds
  • Odd smells, like burning
  • Improper voltage
  • Dim headlights
  • Flickering gauge lights
  • Engine stalling

If you experience any of these symptoms, bring your vehicle into our independent auto repair shop in Fountain for a thorough inspection.
