Power supply advice please
Apollo:
OK so I've got my isolation transformer connected to the mains power on one side ( 2 yellow wires in ) and I've got 2 red wires coming out of the other side that connect to my switching power supply. The red wires are identical. On my power supply I have these connections labeled +5v, GND, GND, -5v, +12v, FG, AC, AC in that order. Which connections do I hook the 2 red wires from the transformer to? I'm guessing 1 goes to AC and the other goes to the other AC? Does it matter which way around they go because I can't tell them apart.
Confused, thankyou.

Anyone care to comment before he blows up his PSU?
'Coz that's exactly what I did and I had the very same problem :D
Surprisingly, it's actually quite hard to find any info on wiring up arcade PSUs.

I don't know what type of isolation transformer is being used but make sure you check the schematic. A true isolation transformer doesn't output DC.
Now there are modern ones that put diodes on the winding taps to output DC but you need to make sure you have what you need.

I don't believe this is the case. He's just running all his cabinet from the iso. Bad move, it puts more strain on it. Use a power distro block instead.

Never, never, never connect anything but a monitor to the output side of the isolation transformer.
