Ok, I have all the wiring from my time soldiers on my bench and it looks to me like the isolation transformer is wired backwards. The wires going to the monitor should come out of the top, shouldn't they? Does it work backwards too or something?
 
I figure it matters if the wiring to the bottom running to your monitor also goes to another part like the power supply or marquee light. I never really thought much about the science between this but I figure it's as simple as the bottom and top lugs just being two separate halves and whichever the monitor goes to can't be connected to anything else at the same time or it'll go boom lol
 
You can wire it up either way, no big deal. You just don't want the monitor on the same side as the ac power coming from the wall. You can wire other things off the same side as the monitor, but if any of them are connected via ground or anything you might have big issues.

I've seen some though that have a voltage drop, too. So if you put 120 in one side, it'll only send 110 out the other side, I think if you reverse it, it actually ups the voltage. So you might get 130 going out to the monitor.
 
Depends on the transformer. If its a 1:1 transformer then it doesn't matter. I believe Nintendo uses step-down transformers so if you were to wire that up backwards... it would become a step-up transformer. Chances are you would blow your monitor chassis at that point.
