Signs of an Alternator Failure

March 18, 2021 Published by Leave your thoughts

If you press the ignition button or turn the key and only hear a clicking sound, you might assume the problem is a dead battery. But the problem could be more complicated than that. It’s possible that the alternator needs to be replaced—and switching out the battery won’t help the problem at all. In fact, a bad alternator would drain a new battery as well.

The alternator is responsible for keeping the battery charged, which allows you to do everything from turning on your lights to delivering power to the engine. If you believe you might have a bad alternator in Lubbock, TX, it’s time to call a qualified auto mechanic for a repair.

Strange noises

It’s possible that as the car ages, the serpentine belt is no longer spinning the alternator pulley, which would lead to alternator problems. This often shows up in the form of a squeaking noise. Another possibility is internal bearings being worn out, which can surface as a grinding or growling sound.

Light malfunction

If you’ve noticed that the headlights suddenly become overly bright or dim, this could be due to a faulty alternator. That’s because the alternator is responsible for your car’s electrical system, and its malfunction means inconsistent voltage supply.

Frequent stalling or problems with starting

If your car stalls often, this could mean that the spark plugs aren’t receiving adequate power from the alternator to make the engine run. If the car won’t start and you hear a clicking sound instead of the standard engine sound, this could also be a problem with the alternator.

Check engine light

Everyone dreads seeing the check engine light pop on. This could be a sign of an alternator that needs to be replaced. Some models even include a specific light to indicate that it’s time for a new alternator.

Replacing the battery doesn’t work

Many people—including those with experience in auto repair—assume that when the engine doesn’t turn over, it’s the battery that’s to blame. But if you replace the battery and the car still won’t start, then you need to look elsewhere. It’s possible that a small light in the car may be sucking the battery dry, or that the lights were left on. But if that’s not the case, the alternator is the most likely culprit.
