I made a temporary jumper that allowed me to swap the wires, and the starter/generator would then actually charge the battery. I cut the original Yamaha wires, installed two spade lug crimp connectors and plugged RED to Green and Green to Red and the golf cart works perfectly.
Now I have no idea if this was a wiring error in the starter/generator or the polarized plug, but with this repair the wires can be reversed again if needed in the future.
The bottom line is it appears reversed polarity on the field winding will cause the generator to not be able to charge that battery.
Hope this helps.
