Here is the 3 prong wiring, wanted to make sure this was correct.
The black wire from the new AC cord goes to the rear fuse holder tab, and to the polarity switch - the side with only one contact.
The AC cord white wire connects to the black wire in the V4 which runs to the other side of the polarity switch and the blue/white wire that goes to the transformer.
Green AC wire grounds to the PT nut.
white wire in the V4 connects to the other end of the fuse holder and goes to the power switch.
