Cars are powerful machines that require a constant supply of energy. While you may be familiar with many of the components that help to power your vehicle, such as the engine and battery, you shouldn’t overlook the alternator. It’s important to understand this component’s function and know how to tell when it’s failing so you can get the necessary auto repairs. Below, learn what an alternator does and how to tell if it is working properly. 

What Does an Alternator Do?

The alternator’s job is to generate energy for your car. Like any generator, it receives power from one source, which in this case is your engine, and spins a belt attached to it. This component could be compared to a hydroelectric generator, where water pressure causes a wheel to turn and generate energy.

The alternator is the true source of electric power for your vehicle’s lights, sound system, seat warmers, and other electronic components. While some may assume that the car’s battery is the power source for all of these components, its main purpose is simply to supply an electric current to the starter. 

How Can You Diagnose Alternator Problems?

When your alternator is malfunctioning or failing, you will likely need to visit an auto repair specialist. Dying alternators can make grinding sounds if the bearings are going bad, or whining sounds if their voltage regulator is failing. Some cars also have a warning light that comes on the dashboard, usually with the letters “ALT.”

If your headlights get dim, the windows start moving slowly, the seat warmers take longer than normal to heat up, or any other electronic component begins performing sluggishly or stops working altogether, it is a sign that the alternator could be failing. The auto repair specialist may also check for other common causes, such as failing bulbs in the case of dim headlights, or frayed wires for slow-moving windows. However, the alternator is the most common culprit and should be looked at immediately.
