Way back in the past I have run into this and in my reading there was
something about brushes "floating" when they are almost gone. Can't
remember the details, but probably related to how much tension is in the
springs holding the brushes in place when they are well worn. It may
very well be time to change the brushes. If your alternator is original,
given the age of our vehicles it's probably time to change them, if for
no other reason than to ensure you don't breakdown at some inconvenient
place.
