A healthy alternator does the important tasks of charging the battery and powering the electrical components while the engine runs. But when it starts to fail, it can lead to a variety of issues that can leave you stranded if not addressed promptly. This makes it important to get to the shop at the first sign of trouble. At Integrity Auto Care, we provide expert alternator replacement and auto electric repair in the greater Belvidere, IL area. Here’s a look at five warning signs of an alternator issue.

Dim or Flickering Lights

One of the most common signs of alternator trouble is dim or flickering headlights, dashboard lights, or interior lights. This happens because a failing alternator struggles to provide consistent electrical power. If you notice your lights becoming unusually dim or flickering, it’s a strong indication that your alternator might be failing.

Battery Warning Light

Modern vehicles are equipped with a battery warning light on the dashboard. When this light comes on, it doesn't automatically mean your battery is the issue—it often signals a problem with the alternator. The light typically looks like a battery-shaped icon. In some cars, the letters ALT or GEN may flash on, which can also indicate alternator trouble.

Unusual Noises

A failing alternator can cause a variety of strange noises. You might hear a grinding or squealing noise coming from the engine area. The grinding noise could be due to worn-out bearings in the alternator, while the squealing noise might indicate a belt problem. 

Dead Battery

A dead battery can often be a symptom of a failing alternator. If your alternator is not charging the battery correctly, the battery will eventually lose its charge and die. While a dead battery can be caused by many factors, if there’s not an obvious other culprit, it’s worth investigating the alternator.

Issues with Electrical Accessories

Since the alternator powers your car’s electrical system while the engine is running, any failure can cause various electrical issues. You might experience problems with your power windows, radio, air conditioning, or other electrical components.
