The alternator is one of many auto parts that help to keep your car running smoothly. When it doesn’t function properly, the electrical systems in your vehicle will eventually fail, and even more importantly, the battery won’t stay charged. This can create several costly problems and put you at risk of getting stranded. As such, it’s essential that you’re able to recognize when your alternator has gone bad so you can get a new one before other issues arise. 

How to Know When You Need a New Alternator

1. Engine Dies After Being Jumped

In the event your vehicle doesn’t start, the first step you might take is to jump it using power from another car battery. If the engine comes to life and continues to run after this, it’s likely the battery causing an issue.

However, if the engine dies within a short time of being jumped, the alternator is usually to blame, as it’s not able to recharge the battery. If your battery has tested good but, you find that your car still needs a jump-start multiple times a week, you should have the alternator inspected.

2. Weak Electrical Accessories 

One of the more obvious clues that something is wrong with your alternator is that the electrical components of your vehicle will become difficult to operate.

This includes features such as the power windows, radio, power seats, air conditioner, and power locks. If you notice these accessories suddenly working slowly or intermittently, it’s a good idea to see if you need a new auto part. 

3. Dimming or Flicking Headlights

Another indication you have a faulty alternator is headlights that flicker or dim while you’re driving. An alternator that’s in good condition will always generate enough power to keep the headlights bright.

If it’s no longer capable of this, you may notice the lights pulsate back and forth from dim to bright as you push on and release the accelerator. This can also happen with the dashboard lights. 

4. Burning Smell 

A strong electrical burning odor can come from various damaged or defective auto parts, including the alternator. Often, an unpleasant smell can develop due to the alternator itself overheating or the alternator belt being restricted in movement, resulting in friction that causes it to heat up. You’ll want to have your car examined right away to identify the exact problem.
