Five Signs You Might Need a New Alternator

Your car’s alternator uses the electrical energy the engine provides to keep the battery fully charged and the car running. Without it, your car would likely run out of energy in a matter of minutes. Therefore, getting car repair for your alternator when needed is essential for keeping your car running. Here are five signs you may need car repair for your alternator.

Car Repair: Alternator Warning Signs

Car Repair for Alternator Issues in Montgomery, AL

1. Your Battery Loses Its Charge Quickly

The alternator’s job is to keep the battery charged. If your car battery won’t hold a charge, either the battery or the alternator is likely to blame. You will definitely need car repair for one of them.

2. Your Car Lights are Dim

Dim lights are another sign that your car is lacking battery power and that car repair may be needed. In addition to dim lights, you may notice your power seats and windows are moving more slowly than normal as well.

3. You Notice Odd Sounds or Smells

Your car’s alternator works with a series of belts. When these belts are too loose, too tight or broken, you may notice odd sounds or smells. If you are handy, you may be able to do the car repair yourself. Otherwise, you’ll need to take your car in to a qualified mechanic.

4. The Warning Light Comes On

Some newer cars have an indicator light that lets you know when you may need car repair for your alternator. It may be shaped like a battery, or it may say “ALT” for alternator or “GEN” for generator.

5. Your Car Won’t Start

Lastly, a car that won’t start very typically needs car repair of some kind. If the problem is a lack of power to the engine, the alternator may be to blame.

If you suspect your alternator is the cause of your car repair problems, there are three ways to know for sure. You can use a voltmeter to test it yourself, take it to an auto parts store for free testing, or take it to a car repair expert.

  1. I’m worried that this may be the issue with my car 🙁 it won’t start, but if my husband jump starts it then it will. Is that still an alternator issue, or something more related to the battery? Thanks!

  2. This is valuable info! I was convinced I had an alternator issue because my car was showing almost all of these signs, and my battery was only 7 months old. When I got it checked out, it turns out the battery was bad and I was able to replace it under warranty. Luckily, it wasn’t anything as difficult as an alternator issue, but now I know what to look for.
