Alternator
The alternator keeps your battery charged and powers your car's electrical systems while the engine runs. When it fails, you might see warning lights, dimming headlights, or a battery that keeps dying. We test your charging system and replace a faulty alternator so your vehicle stays powered and dependable.

Frequently asked questions
What are the signs of a bad alternator?
Look for a battery or charging warning light, dimming or flickering lights, a whining noise, or a battery that keeps going dead. These often point to a failing alternator.
Can I drive with a failing alternator?
It's risky. Once the alternator stops charging, your car runs on battery power alone and can stall without warning. It's best to have it checked right away.
Will a new alternator fix my dead battery problem?
If your battery keeps dying because the alternator isn't charging it, replacing the alternator usually solves it. We test both to make sure the right part gets replaced.
