Installation Notes and Tips

Confirm pulley style, amperage, rotation, and regulator type before installation. This unit uses an 8-groove serpentine pulley, internal regulation, and clockwise rotation, so matching the original charging-system configuration is important for proper operation. Verify the vehicle’s application notes, especially on 2002-2003 Ford F-150 and 1997-2001 Ford F-150 listings that specify optional or 130 amp alternator configurations.
