I restore a lot of generators and occasionally see one that motors, but won't charge. It is usually caused by the output being grounded around the terminal post, a partially grounded field, or a weak brush spring or poor brush contact with the commutator. New brushes need to be sanded in to fit properly. Last year a guy sent me his generator after several days of troubleshooting the same issue. It turned out the be the field interconnection point was grounding on the through bolt. An easy fix.
