Ok, back to daisy chaining PSX1s.? We had one that seemed dead, but tested it separately and found that it worked fine.? The power from the previous PSX1 was zero.? That PSX1 also worked fine, but no power out to the next one.? We can't figure that out.? Anybody have any ideas?? We've powered the originally suspect board from a different board, and everything is okay.? Can we just put a pair of jumper wires in the board that has no output?? Or is that board getting ready to fail?
