Installation Notes and Tips

Verify plug type 933, pulley groove count, rotation direction, and mounting orientation before installation. Confirm belt alignment and inspect the charging circuit, battery condition, and related wiring during replacement. This alternator is not one-wire capable, so the vehicle’s factory charging connections must match the specified configuration.
