Bad Alternator Signs

Quirk Chevrolet | Portland, ME

The alternator is an important part of your vehicle. It keeps your car battery charged. If it stops working, you won’t be able to start the engine, or it will turn itself off after a few minutes. However, before it reaches that stage, there are some warning signs of a failing alternator.

Dead Battery

Most of the time, a dead battery is just a dead battery. However, sometimes, the battery dies because the alternator is going bad. One way to tell is to get a jumpstart. If your car starts and stays running, it is most likely a battery issue. However, if your car stops running again shortly after the jumpstart, it could be your alternator.

Inconsistent Lights

In addition to charging the battery, the alternator also powers your car’s electronic accessories. If it is starting to fail, you may notice lights that are either too dim or too bright. You might also see flickering or erratic lights.

Malfunctioning Accessories

Your car’s power windows are controlled by the alternator. If you notice it is taking longer than usual to go up or down or your electronic indicators are going haywire, this is a good sign your alternator is going bad.

Battery Warning Light

If you see a warning light that is in the shape of a car battery, this is a good indication that something is wrong with the electrical system, including the alternator.

If you notice any of these signs, have your vehicle’s alternator serviced at Quirk Chevrolet of Portland in Portland, Maine.
