Signs it’s Time to Replace Your Alternator

If your car is having trouble starting, the alternator may be to blame. Here are some other signs that it may be time to replace your alternator: 

  • Your car’s battery is dead or dying. If your alternator is working correctly, it can charge the battery. 
  • Your headlights are dimming. This can be a sign that your alternator needs to output more power. 
  • You’re experiencing electrical problems. If your car stereo suddenly cuts out or your power windows stop working, it could indicate a failing alternator. 
  • Your check engine light is on. This could indicate that there is a problem with the alternator belt.

What is an Alternator?

An alternator is a device that generates alternating current (AC) by using a spinning magnetic field. The field is produced by an electric current flowing through coils of wire wound around a central iron core. A permanent magnet surrounds the Iron core. The rotating field creates an induced current in the stator windings, producing AC voltage.

The primary purpose of an alternator is to keep the battery charged, but it also provides power for the electrical accessories while the engine is running. Alternators are typically found in cars and trucks but can also be found in boats, aircraft, and other vehicles.

When an alternator begins to fail, it will usually show signs of wear and tear before it completely fails. These signs can include dimming or flickering headlights, slow cranking of the engine, and strange noises from under the hood. If you notice any of these signs, it’s time to replace your alternator.
