I believe that was the answer, there was and I'm sure there still is questions about
as to the way direct current flows. Up until after the war most all vehicles
were positive ground. I spite of our learning and research I'm sure the opinions
will continue to differ. Generators can be polorized easily to either direction and
I while I haven't tried it would think alternators can be changed by transposing
the dieodes in it. My 2 sense. By the way I had read years ago that Mr Ford
was kind of afraid of electricity.
