    When I've done the motoring test you describe I then use an electric drill to drive the dynamo and check the dynamo output voltage which with a good dynamo off load will be at least 18 volts. It is not unusual for a dynamo to motor and not generate and if all the wiring is sound my attention falls on the armature  paying particular attention to the commutator soldered connections. If there is any sign of the solder having melted it's a rewind because if it's got hot enough to melt the solder the winding insulation in the armature slots will be cooked.
