Buying a used alternator: what to check
- Ask for the amperage rating. The same vehicle can ship with multiple outputs.
- Bench-tested units are worth a small premium; ask for the test result.
- Check pulley type (solid vs clutched) matches your old unit.
- Low-mileage donors matter less here than test results. Brushes wear by hours, not miles.
