I have an Isolated Transformer that I need to wire for my monitor.
You can see it here:
(http://i12.photobucket.com/albums/a222/november84/0055Small.jpg)
There are 2 pins on top, 5 on bottom (2 bent up and were in use before).
I checked out this SITE (http://homearcade.org/BBBB/acwiring.html) to see this wiring diagram:

So the top is for the monitor in the diagram but what of mine? Can I follow this diagram and wire the monitor to the top of the ISO?
Do I just connect either lead to either of the 2 bottom pins sticking out or does it matter which goes where?

I will assume that you are in the United States so yes 115V in and 115V out. Connect to the 0V and 115V terminals.

and polarity doesn't matter? or should I connect the Positive side to IN and Negative side to OUT?

The two top terminals on your transformer are the output to the monitor. "0V" is the neutral (or white or ribbed) wire. "115V" is the hot (or black or plain) wire.
The bottom row is the power input to the transformer. It would appear that the printing on the transformer's label does not line up with the lower terminal. Far left terminal marked "0V" is the neutral (or white or ribbed) wire. Use the "125V" for the hot (or black or plain) wire. The very far right is the "E" (earth or frame ground) terminal which is optional. The power cord green ground wire and green cabinet frame ground wires would connect to that.

Power goes to fuse then to switch, to ISO(white to 0V and brown to 125V) to monitor(white from 0V and brown from 115V). Ground goes from power to ISO and then from ISO to monitor.
I believe the fuse(D250V2A) on the monitor was out before we started. So I tried the fuse in the beginning of the circuit with a 250V(no Amperage listed) and placed it in the monitor. I flipped the switch and heard the monitor turn on and the fuse burnt out.
I'm not sure what caused this as I believe I have it set up properly.
Can you give some insight on what I may check? I'm going to pick up more fuses tomorrow as well.
The original fuse was a D250V2A, the second only said 250V on it I'm not sure if I should go with the D250V2A again or get the 3/3.15 like this thread (http://forum.arcadecontrols.com/index.php?topic=85234.msg893606#msg893606).
