And the 2 people I talked to both gave me about the same scenario. They "tried" to incorporate it internally, but it never truly worked as they wanted so they revised the drawings and owners manuals so they were all consistent and more clear on directional polarity. (Don't know if they meant electrically or fundamentally or as Sergio mentioned, do they really know unless they were an Engineer....(?))

I know the manual I just received and the drawing are very clear through nomenclature and depiction that the banded/striped end of the diode must go to the positive side for correct operation. The drawing shows the stripe side of the Regen diode going to the battery side of the solenoid large post and the stripe side of the coil diode going to the small post that the light blue wire goes to, so hopefully with the more detailed drawings and instructions, users are better at getting them correctly installed.
