"Direction of flow" was a bad choice of words on my part. I was thinking more about the wiring and flow path thru the armature rather than conventional positive or negative current flow.

The polarizing process would not be affected because it relies on the internal wiring of the generator to orient the field shoes in the proper relationship to the armature poles. As soon as the polarizing connection is made the heavy current surge thru the field coils connecting back to ground will cause the shoes to turn into a brief electromagnet. The respective north or south poles are established depending on whether it was a positive or negative going surge.

On a modern generator the process is simple -- the input current goes thru the field coils and then via the closed regulator contacts back to ground establishing the electromagnets. While your particular generator has the direct field connections between the terminal and ground needed I confess to not knowing enough pure theory to understand how the same process can be done on a generator with a fuse in the field coil circuit without blowing the fuse. Hence the earlier question on if or how polarizing was done on those generators.
