The brushes for the slip rings are prolly worn out. If that's the case, I would think that they might be replaceable much less expensively than a new alternator (although at 165K, it might be wise to just replace it with a new one, other things might be getting ready to go in there).
Kurt is right on the money here...
I had my Alternator replaced at about 90,000 miles for the same reason.
When the brushes are worn, the springs are extended to their limit
and at high rpms you get brush bounce, causing the Alternator light to come on.
I replaced the alternator and a month later, the battery.
Now everything is working perfectly !
The Alternaotr in our cars, for some reason, cannot just have the voltage regulator and brushes changed in the field.
I think it is because all of the internal connections of the alternator are welded together.
It can only be sent out to be rebuilt.
