Installation Notes and Tips

Verify the vehicle’s original alternator specifications before installation, including voltage, amperage, plug type, rotation direction, and pulley/belt configuration. This unit does not include a pulley, so the existing setup must match the required 2V belt arrangement. Confirm the mounting ear orientation and connector style against the original part to ensure proper alignment and electrical connection.
