About to re-pin one of the connectors on the power supply board. Hopefully the pictures explain my dilemma. I have a new 3211A power supply board but do not know what the wire running to the fuse holder (orange) and the one soldered to the board (yellow) control. This is the connector that connects like this: OD . I believe the yellow wire is running to the far right pin, but since the board does not work I don't know if I can trust that the previous owner had a clue. Is there a way to find out which is which? If I connect the wrong one what will the outcome be ? Thanks. By the way please disregard the red wire.

Those are the incoming ac wires for the general illumination lights. Ohm out the traces on the front/back and you should have an idea of how its supposed to go. Yellow looks ok. That side of the gi power goes up to the relay and back down to four of the headers on the connector for gi 'out'. The orange is in the wrong place and should be connected on the holes beneath the other side of the fuse holder. Move the wire and install the fuse. That side goes through the fuse then into the other four headers of the GI 'out'. Do not bypass the fuse-thats what the previous owner did!

Here is a quick pic. Don't mind the previous repairs/char

This same power supply was used for system 9 and early system 11, but those games had a four fuse block so each GI string was fused individually. In these games, the GI fuse on the PS is replaced with a jumper wire. Something to keep in mind when swapping power supplies between games.
