Hmm... it might well be an inaccessible direct connection between the coils in the yoke itself. If that's the case, the best you can do for steps 2/3 is test across the yellow arrows. the result can indicate if coils are open. It won't indicate shorts because of the parallel nature of the circuit.

The AC/variac drive test mentioned above will give better information as to the state of the coils, since you get a visible result... If it does indicate a problem in the coils, the test I described would help narrow it down.
