Does the alternator feel hot to the touch? Is the measured voltage consistent? Does the light go off at speeds above 35MPH? How long has this been happening? Are all the wires and connections in good condition? Is the belt tight?
Perhaps a diode or triode, or insulation is failing when the alternator gets hot.
As you may know "shorted" diode can produce the correct voltage but not enough current to properly charge the battery.
I've seen alternators fail after within a year.
Perhaps a brush is sticking. Did you tap the alt. with a hammer (in a sturdy location)?
Just a few ideas.
Good luck.
