Alternator Failure: 6 Common Symptoms

Alternator Failure: 6 Common Symptoms


If your alternator is malfunctioning, then your battery's power reserve could soon run dry, potentially leaving you stranded and needing help. When you first notice an indication that your alternator isn't working properly, you'll want to be proactive about remedying the problem. Here are six symptoms of a failing alternator.

Dead Battery

A brand new car battery should work dependably for three years or longer. But if your battery dies sooner and not for an obvious reason like leaving your headlights on, then a faulty alternator could be to blame.

Dashboard Warning Light

A faulty alternator can trigger a dashboard warning light that reads GEN or ALT, or lights up in the form of a small battery. It's important to always investigate dashboard warning lights so the issue can be taken care of before it gets worse and becomes more costly to fix.

Issues with Electrical Accessories

Newer model vehicles regularly have computers that are able to calculate which electrical accessories should have their power supply reduced when a malfunctioning alternator is detected. This saves more power for the car's most crucial electrical needs. In such a scenario, an accessory such as power seats could start functioning improperly.

Problem with Headlights

Erratic headlight behavior could be due to a faulty alternator. If your headlights start dimming or flickering while you're driving at night on a road that isn't illuminated by streetlights, then your safety could be seriously compromised.

Stalling

A failing alternator can prevent spark plugs from receiving sufficient power. Consequently, your vehicle may stall out.

Problem with Belt

If you at all suspect that an alternator issue could be present, then it's worth popping the hood and taking a quick look. If you see a belt that is cracking or doesn't fit properly, then you may have spotted the cause of your alternator problem.
