  3. Raise vehicle on hoist.
  4. Remove right wheel.
  5. Remove right side splash shield.
  6. Disconnect the field wires.

Generator Removal

NOTE: If stud is not held and stud rotates, the plastic insulator will crack and/or break causing generator to fail.

  1. Disconnect the fusible link wire using generator output stud wrench (SA9401C) to hold generator output (B+) stud from rotating.

  1. Remove the lower and upper generator attachment bolts.

9. Remove the generator through the wheel well opening behind the strut.

This reads like a thorough answer but it leaves me with a few questions.

1. Can you provide more detail on how to properly remove the accessory belt.

2. I'm not sure how to properly identify or disconnect "field wires".

3. I'm not sure how to properly identify or disconnect "the fusible link wire".

4. Is the "generator output stud wrench (SA9401C)" some sort of specialty tool, if so, I likely don't have it and would need to know what, if any, substitute tool I can use to hold the stud from rotating.

and lastly, as of right now none of the images you included are loading for me, in IE or in Firefox (both of which are updated), I'll try it again in the morning when I intend to go ahead with the repair, but I'm sure I'm going to need those to work if this answer is going to be any help.


THANKS SOOOOOO MUCH for all the information you have provided already, if this works out I'd be more than happy to accept, and perhaps add on some sort of bonus if I can.
