Hopefully, this will be the last update here...
The alternator does not have to be removed to change the brushes. Pull the wiring connector, remove the black plastic cover (2 screws, 1/4" drive), to expose the brush housing - white plastic. The brush sets are held in there with 3/16" screws.
I inspected the brushes and found them depleted, I have new brushes in the mail. - - - The excitement continues to build!
On their death bed, nobody ever said, "Gee I wish I'd spent more time at work!"
