Reasons Why an Alternator Goes Bad 

If you’ve been driving your car for over six years, you’ll start to recognize that it doesn’t run as optimally. It’s the best time to check your alternator for any issues. Having a faulty alternator can be a catalyst for other car problems. Here are some reasons why an alternator goes bad. 

A Dead Alternator 

The life of an alternator can last around eight years. However, you may want to look into high-output alternator brands if you plan to customize your vehicle a bit. Car batteries may stay optimal for about five years.

It’s imperative to get a powerful alternator when you start adding a new stereo system or something else that requires more juice. You don’t want to wipe out your battery because it’s expensive to replace. 

A quality alternator is imperative to your vehicle because it takes the mechanical energy and turns it into electricity to charge up your motor. If your alternator dies out, check to see what caused it to go wrong. 

Electrical Problems 

Maybe your car computer is malfunctioning because it’s not powering up like normal. You might have trouble turning on your car. It’s a telltale sign that something is wrong. 

If you notice that you have flickering or dimming lights while travelling, then the alternator has begun to fail to power your headlights. Also, look at the indicator lights. If you see that the warning light comes on regularly, your alternator doesn’t have the electricity for the correct output. 

Other electrical issues may occur: your radio doesn’t work, or your power windows operate slowly. These are some clear warnings that you have a faulty alternator. Make sure you get a professional to take a look at your alternator to see if it’s the culprit. 

Weird Smells 

While a strong smell is not the end-all, be-all of a dying alternator, it’s worth checking out. If an alternator starts emitting a foul odour, it’s usually due to it overheating. It may be pushing too much power through the rotor and stator.

The smell is pretty distinctive, almost like the fumes from an electrical fire. If you notice it smells like burning rubber, a pulley might not be in proper alignment. When the belt doesn’t turn freely, it creates more heat and friction. 
Whether your car stalls or emits a strong odour, you want to do a checkup to rule out any problems. Your best bet may be to replace your alternator.
