Now that my Alternator appears to possibly be a problem I looked at the Bentley Manual, and the alternator can be changed from below. That is the exact method listed in the book.
So this repair should not be that bad to have done, or to do!

- Loosen fasteners -1-, -2-, -3- and -4- and remove noise insulation panel.
CAUTION!
Before removing ribbed belt, mark direction of rotation. Belt damage will result if not reinstalled in proper direction.
