Is my alternator failing?

Is my alternator failing?

To keep your battery charged up and your car running dependably, it's important that your alternator remains in healthy condition. With a failing alternator, your battery's power reserve will become drained, potentially leaving you stranded. Here are seven signs of a bad alternator.

Dashboard Warning Light

A dash light that reads ALT or GEN is often the first indication of alternator trouble. In some vehicles, this light instead comes on in the form of a little battery. Anytime a warning light illuminates, you'll want to try to pinpoint that issue at hand.

Dead Battery

Brand new car batteries should work reliably for at least three years. If yours dies at an earlier age with no obvious cause (like you forgot to turn your headlights off), then an alternator issue could be to blame.

Problems with Headlights

A malfunctioning alternator can cause headlights to start acting erratically, which creates a significant safety concern, particularly if you have to drive at night on roads that aren't illuminated by streetlamps.

Belt Issue

If you have reason to believe that alternator trouble is brewing, then it's worth doing a quick visual inspection. You may have found the source of your alternator problem if you can see that a belt is too loose, too tight, or cracked.

Electrical Accessory Issues

Modern vehicles are often equipped with computers that determine which electrical accessories should first get their power reduced when the alternator isn't functioning correctly. This way, power is prioritized for the vehicle's most crucial electrical functions. This could be why, for example, power seats aren't working properly.

Burning Smell

Day in and day out, alternator drive belts do their job under heavy stress. When they finally start to wear out, they sometimes create a burning odor.


A faulty alternator can prevent sufficient power from being directed to the spark plugs. As a result, your engine could stall.
