Yes, you are right about the , "I may be incorrect part".

{NOTE on a B circuit if you apply voltage to the A terminal, current flows through the armature to ground but NOT through the field windings IE NO POLARIZATION!!! The fields on a TWO BRUSH B start at the external F terminal then to the internal ground with no connection to A other then the armature as well as one end of the fields are both grounded.

DISCLAIMER I did this in a hurry I may be incorrect,....}

See the current path through the field coils in violet when Batt is applied to ARM in a "B" circuit system. As I said, both "A" & "B" can both be polarized by BATT to ARM.
