Wind speed effects RPMs while recharging??

That behavior has no basis in reality. The batteries were charged by virtue of the energized armatures spinning in a magnetic flux, creating an EMF (voltage) greater than that of the batteries. The armatures were turned by the diesels, and they could be turned at any speed, regardless of weather - two completely independent factors. Particularly if the main clutch on one side were disengaged as was common to do, thus the armatures of that motor being disconnected from the propellers, then that side’s diesel has no limitation on how fast it turns that side, only the diesel’s own governor.
