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.
