7 Symptoms of a Failing Alternator

7 Symptoms of a Failing AlternatorYour alternator powers up your battery. If it malfunctions, then your battery's power reserve is liable to run out, which could leave you unable to get moving. Here's a look at seven signs of an alternator problem.

Dead Battery

While it is of course normal for a battery to die at the end of its life expectancy, if you've recently installed a battery and it has died, then alternator trouble could be to blame---unless you forgot to turn off your headlights!

Dashboard Indication

In many cases, the first indication of alternator trouble is the illumination of a dash light that says ALT or GEN. In some models, this light is instead shaped like a little battery.

Problems with Electrical Accessories

A faulty alternator can lead to problems with the electrical accessories including your power locks, power windows, power seats, and radio.

Dimming/Flickering Headlights

Your alternator supplies the power to your headlights. If it goes bad while you're cruising down a road without street lights, then your visibility could be reduced to a very unsafe level.

Problem with Belt

If you pop the hood and can see that a belt is too loose, too tight, or has cracked, then you may have spotted the source of your alternator problems.


A healthy alternator will help to ensure that your pistons continue to pump dependably as you chug down the road.

Burning Smell

While many automotive problems can cause a burning odor, one possibility to consider with this symptom is a slipping alternator belt.
