OK!!One basic rookie mistake... I assumed it had fuses in it. It did not. This is why I was getting normal 120v readings from the female end of the IEC power cord but no power going through to the other side.
So I looked around to see if I had any fuses and luckily, I had some left over from my Bottlehead or Hagerman Cornet build. (Bottlehead and Hagerman both put every little detail on paper, so all I had to know how to do was solder and measure voltages according to the manual...easy).
125A/250V 5x20mm SLO-BLO fuses.. (a question about that will come at the end)
Put the fuses into the IEC module and set up a VERY DANGEROUS bench test with the leads going into the hot and neutral as instructed and the output leads on the rubber pad that I have covering the workbench.
Plugged the thing in and viola! 17.8 Volts off the black and red leads and 17.79 Volts off the orange and yellow leads.
It was a simple solution. Fuses.
Now comes the next issue. Encouraged by this excellent result, I turned the switch on and off a few times and measured to make sure it hasn't been a fluke. All is well.
I then proceeded to (after disassembling the whole deadly thing, the reassembling with the board) connect the red and black and orange and yellow to the board. Flipped the switch on, and measured at the blocks on the board, nothing. One of the fuses had blown.
I'm going to call it a night, and see about getting the correct connectors for the IEC pins. I don't want to damage it ($24) by overheating it with an iron later on, and for safer bench testing.
QUESTION... should I get different value fuses? Are those OK?
Thanks again everyone! I will post pictures and what the troubleshooting reveals.
