What Does an Alternator Do?

Many Gothenburg and Ogallala drivers think that the battery is responsible for all the electricity in their vehicle, but the alternator actually plays a huge role in powering a car. So, what is an alternator and what does an alternator do? Your alternator sends power to the entire electrical system when your car is in motion. The battery is actually just responsible for getting your car started, but once you start cruising, your alternator acts as a generator to convert fuel into electricity. And as you might expect, huge issues can arise when your alternator is on the fritz. Find out the warning signs of a failing alternator, and learn how much is an alternator on average at Jerry Remus Chevrolet!

How Long Does an Alternator Last?

Before we get into the cost of an alternator, how long does an alternator last? Most McCook drivers go between 80,000 and 150,000 miles or seven years before getting a new alternator. This is just a rough estimate, and your alternator’s longevity will depend on several factors: your alternator’s quality, your driving habits, and how heavily you utilize your car’s electrical system.

What Are the Red Flags of a Bad Alternator?

Now you know what does an alternator do, so how do you know when it’s time for a replacement? Usually, you’ll notice issues with the electrical system. But, there are a number of other warning signs that are worth remembering:

• 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?

If you’re having trouble with your vehicle, it’s easy to mistake battery issues for alternator issues – and vice versa! So, how do you narrow down the issue? We recommend visiting our service center for a complete diagnosis and repair. This is the only surefire way to accurately diagnose your issue.

But if you’ve recently had a jump-start, you can find a few clues there. Did the jump-start solve your problem? Then your battery is probably the problem. Did your car immediately shut off after the jump-start? Then the alternator couldn’t keep the vehicle on, and you’ll likely need a replacement.
