Car Battery or Alternator: How to Know Which One is the Problem

Have you recently tried to start your vehicle, only to find it won’t? Does the key turn, but the engine fail to turnover? If so, you may have a problem with the battery or the alternator. Quanz Auto Body discusses how to know which one is the culprit, so you can get your car running back at its optimal performance again with this week’s blog.


Car Battery Failure

Recognizing car battery problems before they occur can help you prevent potential problems causing you to be on the side of the road.

A car battery works by converting chemical energy into electrical energy. There are several signs a driver should pay attention to that could be warning them of an imminent car battery failure, such as:

  • Hesitant start-up
  • Failure to start
  • Stalling
  • Dim interior or exterior lights
  • Weak power (quiet radio, etc.)

The battery has one main purpose and that is to start the vehicle and keep it running. If you are having any of the difficulties above, your battery may be the cause of your vehicle problems. Always check your battery first before checking on other possible problems.

Alternator Failure

The alternator in a vehicle helps start up the battery and keep it charged. If the battery is working properly then the alternator is likely the culprit to your failed engine. Quanz Auto Body recommends testing your alternator by running your car and then unplugging the positive connection of the battery. If your vehicle stops running, then the alternator is the problem.

Another way to test the alternator is to look at your vehicle’s interior lights. If the interior and dashboard lights begin to fade as your vehicle is running, this indicates a problem with the alternator not charging the battery properly.
