The cutout relay opens up in response to large currents flowing into the
generator when it comes to a stop. Since the generator never came to a stop
there was no large current. And the lower lever of current flowing into the
generator to spin it was not sufficient. I suspect there is nothing wrong with
the control box.
The same thing happened to my MG back in the 70's. New belt and all was fine.
