by | May 2, 2022 | Auto Repair Shop

The alternator utilizes rotational engine power to keep the car running. A certain voltage is required to keep the battery charged as you drive. An ageing alternator will not be able to maintain the correct voltage.

How Do I Know If My Alternator Is Bad?

Typically an alternator will last from 7 to 10 years. However, there are times when this lifespan is shortened. Therefore, it is important to be aware of the signs of a bad alternator. Bad alternator symptoms range from a warning light on the dash to electric failures. Keep reading to learn what to look for when it is time to replace your alternator.

1 – Bad Alternator vs. Bad Battery

Sometimes a dead battery is just that and nothing more, but other times a dead battery could be a sign of alternator failure. An alternator going bad will not be able to charge the battery sufficiently when the engine is running, which will cause faster depletion than usual. To determine if it is alternator problems or the battery, jumpstart the car. If it keeps running, it is time to replace the battery. On the other hand, if it dies shortly after jumpstarting you likely need to replace the alternator.

2 – Warning Light on the Dash

When you start the car, it will make sure the alternator voltage output is correct. If the alternator is functioning correctly, the alternator warning light will turn off after just a few seconds. If the light remains lit, it is a sign of car alternator problems.

3 – Lights are Dim or Overly Bright

When you have an alternator going out, you will get inconsistent voltage to the electronic accessories of your vehicle. You may notice your headlights flickering, becoming extremely bright, or too dim.

4 – Frequent Stalling

When the spark plugs are not getting adequate power from the alternator, it becomes difficult for the car to keep running. If your car begins to stall often, the culprit is often alternator issues.

5 – Odd or Unfamiliar Noise

Certain noises often indicate that your car is not running properly. If you notice a whining or growling sound coming from under the hood, you need to get a professional alternator diagnosis as soon as possible. This sound can indicate a misaligned alternator belt or bad bearings in the rotor shaft.

6 – Foul Odor

Parts of the alternator may be wearing out if you start to notice a smell of burning wires or rubber. This indicates that the alternator belt is under friction or tension. It could also indicate an overworked alternator causing damaged or frayed wires.

7 – Failure of Electrical Accessories

Alternator issues can often lead to problems with the electrical accessories in your car. If you notice problems with your radio, door locks, or power windows, it may be time to replace your alternator.
