Installation Notes and Tips

Verify the 28SI series, J180 mount type, 10:00 Bat Term clocking, and 12-volt system requirements before installation. Confirm the vehicle’s charging-system specifications and connector orientation against the removed unit to ensure the replacement alternator matches the original layout. For Chevrolet and GMC applications, compare the OE number and mounting style carefully before final fitment.
