The first step to work on an alternator requires turning off the battery power. Service the alternator by first loosening the tension then taking off the accessory
Drive Belt from the generator pulley. Notice that releasing the wiring harness from the generator bracket requires the removal of the pin-type retainer. From here you should disconnect the generator electrical connectors by taking off the nut while setting aside the cover. The generator bracket must be unbolted first then you can remove the generator by loosening the attaching bolts. Follow the reverse order of steps when putting the generator back in place.
