Common Indications of an Alternator Problem


For your battery to remain properly charged up, you need a healthy alternator. If your alternator is faulty, your batter's power reserve is liable to become depleted, which could potentially leave you stranded. Here are six signs of a bad alternator.

Dashboard Warning Light

A warning light is often the first sign of alternator trouble. In many vehicles this warning light comes on as the letters ALT or GEN, while in others it illuminates as a little battery. Anytime you notice a warning light turning on, it's important to determine what exactly is triggering it.

Dead Battery

When you put a new battery in your car, it should work depenably for at least three years. If it dies at an earlier age without an obvious cause (like leaving your headlights on), then alternator trouble could be to blame.

Trouble with Electrical Accessories

Modern vehicles often have computers that determine which electrical accessories should first have their power supply reduced when the alternator is malfunctioning. This way, power is saved for the vehicle's most essential electrical functions. If an accessory like your power seats isn't working right, this could be why.

Problems with Headlights

With a faulty alternator, your headlights may start behaving erratically. When headlights dim or flicker, your safety could be jeopardized, especially if you're trying to navigate at night on a road that doesn't have street lamps.

Stalling Out

A failing alternator may prevent sufficient power from being directed to the spark plugs, which could result in the engine stalling out.

Belt Issue

If it seems like there's trouble brewing with your alternator, then it's worth doing a quick visual inspection. If you see a belt that is too loose, too tight, or cracked, then you may have discovered the source of your alternator problem.
