Signs of a Failing Alternator
A failing alternator drains the battery until the engine stops. Watch for these early warnings.
Battery or charging light on
The red battery icon or a charging system message means output has dropped.
Dim or flickering lights
Headlights that dim at idle and brighten when you rev point to weak or unsteady output.
Battery keeps going dead
A good battery that needs repeated jump starts is not being recharged while you drive.
Whining or grinding from the engine bay
Worn alternator bearings whine, and a failing pulley or diode can add a growl or buzz.
Electrical accessories acting up
Slow windows, a resetting radio or warning lights that come and go signal low system voltage.

Why Buy Your Used Alternator From Us
One model can use several alternators with different amperage, plugs and pulleys depending on engine and options. Our process is built to get the exact unit the first time.
Matched by VIN, engine and amperage
We check your VIN and engine, then confirm the amperage rating, connector and pulley type before quoting, so the alternator charges correctly from day one.
See your alternator before it ships
After you order, the supplier photographs the actual alternator once it is pulled. Nothing ships until you approve those photos.

A weak battery, corroded cable or slipping belt can look like a bad alternator. We tell you the quick checks to run first, so you only buy what you need.

How much does a used alternator cost?

What are the signs of a bad alternator?
A battery or charging warning light, dim or flickering lights, a battery that keeps going dead, whining from the engine bay and accessories that act up are the usual signs. See signs of a failing alternator.
How do I know if it is the alternator or the battery?
With the engine running, a healthy charging system shows about 13.5 to 14.5 volts at the battery. A reading near 12 volts or lower while running points to the alternator. If the car starts with a jump and then dies soon after, the alternator is the likely cause.
How do I find the correct alternator for my vehicle?
Use your VIN and engine size, then match the amperage rating on the alternator label, the plug shape and the pulley type. Vehicles with tow or luxury packages often use a higher output unit.
How long does a used alternator last?
It depends on its mileage, heat exposure and your electrical load. Many OEM alternators run well past 100,000 miles in total service. Read how long used alternators last.
Can I drive with a bad alternator?
Only until the battery runs down, which can be a few miles. When voltage drops, the engine can stall and power steering assist may be lost on vehicles with electric steering. Replace the alternator before driving any distance.
Do your used alternators come with a warranty?
Yes. Every used alternator comes with a 30-day parts-only warranty. Labor costs are not covered. Full terms are in our warranty policy.
Do you ship used alternators across the United States?
Yes. Alternators ship by parcel carrier to the billing address on your card, with tracking details emailed within 2 days of shipment. See the shipping policy for details.
