What’s An Alternator And What Does It Do?

There are many moving parts and pieces in your vehicle–so when something is out of whack, it can be difficult to pin-point the issue. To better take care of your vehicle, it’s essential to learn about these many moving parts. Today, we’re going to chat about your alternator. 


An alternator is an essential component of a vehicle's electrical system. It plays a vital role in keeping your car running smoothly. 


In this blog, we'll explain what an alternator is, what it does, and the signs of its failure. We'll also provide some tips on how to maintain and repair an alternator and why it's essential to have regular inspections at an experienced auto repair shop.

What Is An Alternator? 

So, what is an alternator? It's an electrical generator that uses mechanical energy to produce electrical energy. Alternators are connected to the engine via a belt, converting the mechanical energy the engine creates into electricity. This electricity is then used to recharge the car battery and power the vehicle's electrical components, such as the headlights, radio, and other electronics.


The alternator is often confused with the battery but serves different functions. The battery stores electrical energy while the alternator produces it. The battery keeps the electrical components of the vehicle running when the engine is off. At the same time, the alternator recharges the battery when the engine is running.

Signs of a Failing Alternator 

When an alternator starts to fail, there are a few telltale signs. These may include dimming headlights, a dead battery, stalling, or other engine problems. If you notice any of these symptoms, having your vehicle inspected by a professional auto repair technician like the one here at Import Auto Specialists as soon as possible is essential. Driving with a faulty alternator can cause further damage to your vehicle and make it unsafe to operate.

Alternator Maintenance & Repair

Regular alternator maintenance is critical to keeping it running smoothly and efficiently. This can include inspections, cleaning, and replacing worn parts, such as brushes, bearings, or voltage regulators. Diagnosing and repairing a faulty alternator can be tricky, so it's essential to have an experienced auto repair technician do the work.
