The dynamo should not motor with voltage applied to only the field. Even if
there was a fault in the field winding (a short between to windings in the
field). But I think you're right, there is a short. The short is between the
F
terminal and the D terminal. That would explain both the motoring and the
full output under way. you might be able to find and resolve it by pulling the
back off of the unit.
Good luck.
