Buyer's checklist
What to check before buying a used alternator
- Match the amperage rating to your vehicle's spec — a lower-amp alternator will undercharge, especially with aftermarket electronics.
- Spin the pulley by hand: it should rotate smoothly with no grinding or wobble.
- Check the connector plug type. Some models switched connector styles mid-generation.
- Ask about output testing — a good yard will bench-test and confirm the unit charges at the correct voltage (13.5–14.5V).
