Both the motoring test and the test with an electric drill are done with a link between the D & F terminals and the voltage measured between the case and D terminal. Once I am sure that all the connections and the field coils are sound with no insulation faults it only leaves the armature as a possible cause of failure. I don't have a growler, for testing armatures, and I have in the past put a known good armature in a dud dynamo to prove that the armature was the cause of failure.
