Common Warning Signs of Alternator Trouble

 

A faulty alternator can cause your battery's power reserve to become depleted to the extent that you're unable to get moving. When you first notice a sign of alternator trouble, you'll want to be proactive about addressing it. Here are six signs of a failing alternator.

Dashboard Warning Light

A malfunctioning alternator can cause a dashboard warning light to turn on. This warning light commonly reads GEN or ALT, but in some cars it illuminates in the form of a battery symbol. Anytime a warning light comes on, it's important to figure out what exactly is triggering it.

Dead Battery

When you install a new battery in your car, it should work reliably for at least three years, if not significantly longer. If your battery dies sooner than this timeframe and not for an obvious reason like forgetting to turn off your headlights, then you could be dealing with alternator trouble.

Malfunctioning Electrical Accessories

Modern vehicles are commonly equipped with computers that determine which electrical accessories should first have their power reduced when a faulty alternator is detected. This saves power for the vehicle's most essential electrical needs, but may cause issues with certain accessories such as power seats.

Issues with Headlights

Alternator trouble can cause headlights to start dimming or flickering, which could create a serious safety hazard if you have to drive at night on roads that aren't lit up by street lamps.

Stalling

When the alternator isn't working properly, spark plugs may not receive adequate power. This could cause your vehicle to then stall out.

Problem with Belt

If you suspect that your car may be experiencing alternator trouble, then it's worth popping the hood and taking a quick look. If you see that a belt is cracking or poorly fitting, then you may have found the source of your alternator issue.

If you need auto repair, be sure to bring your vehicle to a reputable mechanic.
