What Does an Alternator Do?

Your car’s alternator plays a vital role during your commute, but what does an alternator do exactly? The alternator is responsible for powering your entire electrical system when your car is on the Hudson roads. Some drivers think that the battery supplies the car’s electricity, but the battery is actually just responsible for starting the car. 

Once your vehicle is up and running, the alternator acts as a generator to convert fuel into electrical power. What are the signs that your alternator is malfunctioning and how much is an alternator replacement? Find out with Sawyer Chevrolet, Inc., and contact us with all of your automotive questions!

How Long Does an Alternator Last?

Two common questions we hear are “How long does an alternator last?” and “How much is an alternator?” Most Windham drivers go between 80,000 and 150,000 miles or seven years before getting a new alternator. This will vary depending on your alternator’s quality, your driving habits, and how heavily you utilize your car’s electrical system. The price of your alternator will also vary, so don’t hesitate to ask our service center for a quote!

What are the Red Flags of a Bad Alternator?

Now that you know what does an alternator do, it’s easier to understand the importance of this vital component. So, what are the signs that your alternator is starting to fail? You’ll notice problems primarily with the electrical system when driving around Saugerties. Here are some of the most common signs that our technicians notice:

• Battery warning light appearing on the dashboard
• Dim headlights or interior lights
• Burning rubber smell under the hood
• Devices not charging
• Whining or screeching sound after the vehicle has started
• Unable to start

Is It the Alternator or the Battery?

As mentioned above, many drivers mistake alternator issues for battery issues – and vice versa. If your car needs a jump-start, you’ll have your answer quickly! If a jump start resolves your issue, you probably have a dying battery. If your car dies immediately after the jump start, your alternator can’t keep the car going and needs to be replaced.
