Before you plug the unit in - what do the molex pins and sockets look like? Clean and all pins the same length ?

I have checked at the plug and at the control board. I have 240 volts but the transformer is loosing a leg. I unplugged the transformer and checked at the board. This is a GE Zoneline heat pump PTAC model #AZ65H15DABW1. I have checked the inline fuse and I do have continuity across it. The connections seem tight and I see no broken wires.
I have even brought in someone more knowledgeable than me and they weren't able to figure it out. Thinking the new board was defective, I put the old board back in, it still wouldn't power up. I called GE and was told they have no dedicated tech support. I haven't been able to find a wiring schematic for this unit what I have only shows plug connections on the board.
At this point I figure the problem is somewhere in the wiring, but I have been unable to locate. My theory right now is that somewhere was a wire that was frail and the pulling of the unit to replace the board finished it off but Ill be dogged if I can locate. At this point I just need another direction to look.At this point its personal. I figure if it happens once it will happen again that is why I want to resolve this. Any help would be greatly appreciated.
