Volvo Parts 101: What Is the Alternator?

Volvo parts are designed to help your vehicle operate smoothly and safely. Among these, the alternator plays a prominent role in powering your vehicle’s electrical systems. Our technicians at Volvo Cars Gilbert are here to highlight how the alternator works and how to troubleshoot potential issues.

What Does an Alternator Do?

Your Volvo vehicle’s alternator can convert the mechanical energy from your engine into electrical energy via an alternating current. The electricity is used to power your vehicle’s air conditioning system, headlights, and radio. The alternator also helps your vehicle’s battery recharge as you drive, allowing it to maintain its power to start the engine.

What Are the Warning Signs of a Faulty Alternator?

Although your Volvo vehicle’s alternator can typically last at least seven years, it can become prone to wear and tear over time. Some warning signs that indicate that your alternator needs to be inspected or replaced include dimming or flickering headlights, unusual grinding sounds, and an illuminated warning light on your dashboard.

How Do I Troubleshoot My Vehicle’s Alternator?

One way to troubleshoot your alternator for underlying issues is by inspecting the belt connected to your engine. A loosened or cracked serpentine belt can impact its ability to transfer energy to the alternator to power your vehicle’s electrical systems.

We also recommend checking if your alternator’s voltage output is between 13.8 to 14.5 volts while running your engine. If the voltage output is lower than this range, it could indicate that your alternator has trouble charging your vehicle’s battery.
