The field coil direction of pole shoe windings has to be observed during assembly. One side is a north and the other is a south as far as the field polarity is concerned. It seems to be that they were inadvertently swapped.

If you look at a Ford electrical diagram, a person can look at the direction of rotation of each coil in the set. One is wound clockwise and the other is counterclockwise. A person has a 50/50 chance to of success. It really gets fun on the powerhouse generators with their multiple coils.

Starter motors are shunt wound so they can only turn one way no matter the polarity. A generator is a different story.
