What Is An Alternator?

We’ve all seen those medical dramas on TV, someone is flatlining and outcome the lifesaving paddles to jump-start those heart monitor beeps back into action. Imagine that an alternator serves the same purpose as those life-saving paddles. An alternator is the spark of life that your car depends on each time it starts up. Without a working alternator expect your car to flatline.


The alternator is a small, maintenance-free, generator of electric power that is found bolted to the engine and is driven by a serpentine belt. An alternator gets its name from the term “alternating current” and should last roughly 10-15 years without any repairs. Any car with an internal combustion engine (with the exception of some hybrid vehicles) is equipped with an alternator. The alternator is what charges the battery and it also supplies power to the car’s electrical systems. Electrical systems include the instrument panel, radio, climate controls, and the interior/exterior lights.


What Causes An Alternator To Fail?

What Causes An Alternator To Fail?

There are a few reasons that can cause parts of the alternator to fail and most of the time, these failures cause the entire unit to be replaced. The following issues may be the cause of your failed alternator:


  • Dying battery

If your battery is dying this puts added stress on the alternator causing it to work overtime and wear out quickly. Since the job of an alternator is to charge the battery while the car is running and to also give life to the electrical systems in your car (lights, radio, etc.) the alternator when having to keep a dying battery alive will overwork itself.


  • Failed plates

There are three rotating plates that span across a winding of copper wires, this is how an alternator produces power. As these plates fail (which can happen one at a time) it can weaken, but not entirely stop the power output. When the plates fail, the power will drop power levels. This wear and tear will ultimately cause the battery to fail and the ignition system to die.


  • Worn ball bearings

There is a rotor that spins on a set of ball bearings on the interior of the alternator. When these bearings wear out, they can “snag” as they develop flat spots. This can cause a boisterous clamor and can become a prolonged grinding noise. This racket can be so loud that it can drown out your radio and the engine noise.


  • Loose or disconnected ground wire

The alternator serves as the mounting point for the negative ground wire. This wire Is usually mounted to the vehicles trame with a large wire that can come loose. If the alternator loses its ground, it can surge and cause severe damage to the alternator and the components within it.


  • Damaged drive belt

            If there is a worn or damaged drive belt it can cause slipping to happen on the

alternator’s pulley wheel. If this happens it can cause the alternator to put out less voltage. Without a properly fitted belt, it can cause the alternator to undercharge the vehicle’s system which will in turn damage the alternator and kill the battery.

How To Tell Your Alternator Is Failing


Now that you understand what causes an alternator to fail, let’s examine how you can self diagnose a failing alternator on your vehicle. Once an alternator starts to fail there are six sure-fire warning signs that can determine whether or not you are going to need to take a trip down to a mechanic and open up your wallet to this costly repair.


  1. Barely there lights

Like previously mentioned, an alternator’s sole purpose is to provide power to the ignition, starter and all of the electronic systems in your vehicle. You may notice dim lights both inside and outside, such as dim headlights or dim dashboard lights. These dim lights are usually key clues of possible alternator failure.

  1. Dying or weak battery

A car battery does not have eternal life. Even with a properly functioning alternator charging your car’s battery the alternator can only do so much, eventually, the battery will no longer accept a charge. To troubleshoot this issue and clarify if it is the battery that has failed or if you do indeed have a failing alternator, simply charge the battery and restart your car. If the car still has trouble starting even after a full charge, you are likely facing an alternator replacement.


  1. Dashboard warning light

Modern cars nowadays will usually have a dashboard warning light that will indicate when you alternator may soon be knocking on death’s door. The light will usually be shaped like a car battery but be sure to check your owner’s manual for clarity


  1. Weird sounds

If you hear a grinding or whining noise it could be because one of the many internal parts of your alternator has become worn out or is entirely broken altogether.


  1. An odd smell

This ties back to the damaged drive belt. If the belt is not able to move around freely this friction will cause the belt to overheat resulting in the oh so pleasant aroma of burnt rubber. This will cause poor alternator output. Try tightening the belt, if this does not remedy the smell or change the alternator output the alternator could be failing.


  1. I spy a worn belt

Visual cues are your friend and is one of the easiest things to detect. Look under the hood and check your belts, make sure they are properly connected to the alternator and not too loose, too tight, cracked or worn.
