What Does the Alternator Do?

Your alternator is more than just another car part—it’s the system that keeps your entire vehicle powered. While the battery starts your engine, the alternator keeps it running by:

• Recharging the battery as you drive
• Powering headlights, dashboard lights, and electronics
• Supplying energy to safety systems like ABS and airbags
• Supporting modern features like heated seats, navigation, and infotainment

Without a healthy alternator, your car’s electrical system simply can’t function.

Signs of a Failing Alternator

Your car often gives early warnings before an alternator fails. Common symptoms include:

• Dimming or flickering headlights
• Dashboard warning light (often a battery or ALT symbol)
• Electrical issues such as malfunctioning power windows, locks, or radio
• Unusual noises like grinding or whining from under the hood
• Dead battery or repeated need for jump starts

If you notice one or more of these symptoms, it’s best to get your vehicle checked immediately.

Why Alternators Fail

Alternators can wear out over time due to:

• Normal wear and tear – Bearings, brushes, and other components eventually wear down
• Overuse of electrical accessories – Running lights, heated seats, and other electronics all at once can stress the system
• Bad voltage regulator – Causes lights to appear too dim or too bright
• Heat and moisture – Common in Seattle weather, these conditions can damage internal components

Preventative Maintenance Tips

You can extend the life of your alternator and avoid costly repairs with a few simple habits:

• Don’t overload your car with too many accessories at once

FAQs

What happens if my alternator goes out while driving?
Your car will eventually lose power because the battery won’t recharge. Lights, electronics, and the engine may shut down completely.

Can a bad battery damage my alternator?
Yes. A weak or failing battery forces the alternator to work harder, leading to premature failure.

How long does an alternator last?
Most alternators last between 80,000–150,000 miles, depending on driving habits and vehicle use.

Do you use new or rebuilt alternators?
We use high-quality new and remanufactured alternators that meet or exceed manufacturer standards.
