There are no LED's lit on the mother/logic board etc so my Q being is the mother board faulty?
 
I tested the PSU at the transformer out put ( 5output (5 pin plug plug) and I am getting 12.something12 something volts between brown and the two blacks, however no voltages from the two greysgrey? Correct or not?

I have not tested the multi pin plug at the mother board from the DC board as I cannot find any schematic diagrams as to what the connections are
 
I need help quick as I have ordered another mother board and have rebuilt this iMac at least 5 times in the last 48 hours! and it is driving my Mrs barmy! ha ha
 
Thanks
