How to Recognize an Alternator Problem

How to Recognize an Alternator Problem

A faulty alternator can exhaust the battery's power reserve and consequently leave you stranded. At the first sign of alternator trouble, you'll want to be proactive about addressing the issue. Otherwise, you could find yourself stalled out. Here's a look at seven signs of a failing alternator.

Dead Battery

While it's of course normal for a battery to die at the end of its expected lifespan, if you recently installed a new one and it died, then there's reason to suspect an alternator problem.

Dashboard Indication

In many instances, the first sign of an alternator issue will be the illumination of a dash light that reads GEN or ALT. In some vehicles, this warning light will appear as a little battery.

Belt Issues

If you pop your hood and can see that a belt isn't properly fitting or has cracked, then you may have spotted the source of your alternator trouble.

Issues with Headlights

Your alternator supplies the power to your headlights. If it's faulty, then you could find yourself with headlights that start to dim or flicker. This poses a significant safety concern, especially if you regularly drive on roads that don't have streetlights.

Problems with Electrical Accessories

A malfunctioning alternator can lead to issues with electrical accessories including your power seats, power locks, power windows, and radio.


A healthy alternator plays an important role in keeping pistons pumping dependably. If your alternator goes out, you could end up stalled out and in need of assistance.

Burning Odor

While there are several problems that can cause a burning smell, one potential culprit is a slipping alternator belt.
