Installation Notes and Tips

Confirm the original alternator matches the 50 amp rating, internal regulator setup, clockwise rotation, 12:00 clock position, and 4-groove serpentine pulley before ordering. Compare the connector, mounting points, and belt alignment to the removed unit. After installation, check charging voltage at the battery and inspect belt condition and tension to confirm proper system operation.
