Your vehicle’s alternator keeps your car’s electrical systems running and recharges the battery while the engine is on. When it starts to fail, you’ll notice certain warning signs that shouldn’t be ignored. At Freeport Automotive, we provide expert alternator replacement and auto electric repair in the greater Sacramento area. Here are five signs that your alternator is failing.

Dimming or Flickering Lights

One of the most common signs of alternator trouble is dimming or flickering headlights. The alternator provides power to the lights, and if it’s not working properly, it won’t supply a consistent amount of electricity. If you notice your headlights becoming dim, there’s a good chance it’s due to a failing alternator.

Warning Light on the Dashboard

If you see an illuminated battery-shaped light or one labeled ALT or GEN, it could be indicating a problem with your alternator. Don’t ignore this light—it’s a sign that the charging system is malfunctioning, and immediate attention is needed to avoid being stranded.

Strange Noises

A faulty alternator can create unusual sounds. If you hear a whining or grinding noise coming from under the hood, it could be due to a failing alternator. These noises may be caused by belt or bearing issues. 

Electrical Accessory Problems

A failing alternator can cause various electrical problems. If your car radio, power windows, or other electrical accessories are not working properly or are sluggish, it could be due to a lack of power from the alternator. 

Dead Battery

If your battery dies frequently, the alternator could be the culprit. While batteries do wear out over time, a dead battery that occurs soon after being replaced may point to an alternator issue. The alternator’s job is to keep the battery charged, and if it’s not functioning, your battery will drain more quickly than normal.
