OK to make a long story short, I was trying to repair a board hack on my BTTF power supply board where the previous owner had removed the molex connector, hard-soldered the wires to the board and shoved in butt splices about 6" from the board. When I was cutting the wires out, I realized that there were a few wires that were the same colors, so I wrapped black tape around 1 of each wire (orange and white). Took my boards to the electronic repair shop and told him to make sure that the wires ended up back in the same spot. I didn't take any pictures of the wires at this point (shame on ME!, after taking 20+ pictures of the wires BEFORE I put on the tape). To make a long story short, 4 weeks later I picked up my boards and I was handed a pile of wires that were not connected to the board. The repair shop had not taken any pictures so I was SOL.
The orange wires tie back into the same connector so those are good.
The white wires come off of connector CN1 (pins 4 and 9) on the power supply board and snake their way down to the 12 pin connector (pins 2 and 3) downstream of the transformer. Coming off one end the transformer 1 wire is white/red and the other end of the transformer is a white/yellow wire and they both become white. Assuming 1 end of the transformer is hot and the other is neutral. I can't find a good description in any DE manual (DE simp, POTO, BTTF, etc) to actually tell me which white/yellow(red) is hot or neutral so I can't fix this.
IMO the easiest thing to do is do a quick continuity check between CN1 pin 4 or 9 and the 12 pin connector downstream of the transformer and check pins 2 and 3. If someone could do this it would be AWESOME. If someone has a better approach, please let me know.
PLEASE HELP!
