Installation Notes and Tips

Verify pulley groove count, plug type, rotation direction, and amperage rating before installation. This unit uses an internal regulator and does not use an external regulator or one-wire setup. Confirm vehicle fitment by year, make, model, and alternator output rating, especially on Ford E-350 Super Duty applications noted through 07/2016 and up to 155 amp alternator configurations. Proper belt routing and connector alignment are essential for correct installation.
