Generator Cutouts normally stick closed. If that happened, the battery would have tried to discharge back through the generator, and may have damaged the windings.
While you're looking at your charging circuit, you might want to consider a diode cutout to replace the original. Be sure to order one for the voltage and polarity of your car. I am assuming you're vehicle is original at 6v and Positive Ground.
If your generator was only putting out 1.5 to 2 volts, I would suspect field windings, but do check that all of the brushes have spring tension against the commutator.
