7 Common Signs of Alternator Trouble

7 Common Signs of Alternator TroubleYour alternator supplies the power to your battery. If it fails, then your battery's power reserve could become depleted to the extent that you end up stranded. At the first sign of an alternator problem, you'll want to be proactive about addressing it. Here's a look at seven symptoms of a failing alternator.

Dead Battery

Generally, a car battery should last for around three years. If yours dies much earlier, then the alternator could be to blame---unless you forgot to turn your headlights off!

Dashboard Indicator Light

If you see a dash light illuminate that reads ALT or GEN, then alternator trouble could be brewing. This is often the first sign of an alternator problem. In some vehicles, this light comes on in the shape of a battery.

Dimming or Flickering Headlights

Your alternator powers up your headlights. If it fails, then you may end up trying to navigate through darkened streets. This especially poses a safety hazard if you have to drive on roads that don't have street lamps.

Problems with Electrical Accessories

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

Belt Issues

A belt that is too loose, too tight, or cracked could be the reason that your alternator is having trouble.

Burning Odor

While various types of car trouble can cause a burning smell, one potential culprit to consider is a slipping alternator belt.


To keep your pistons pumping dependably as you drive down the road, you need a healthy alternator. If your alternator malfunctions, you could end up stalled out and in need of assistance.
