Noticed your post but don't know where to start without some sort of diagram other than to (dub) check the power outlet and the fuse. Assuming you've got the leads to the Mypin hooked up for power something ought to light up on there.
I think I'd get hold of Frozone and he'll walk you through it I'm sure.
So far the stuff I've found shows Pins 1 & 2 being the power input pins. If that's the way your's is you should be able to read voltage there. Double check that's the way your's is shown on the controller itself - apparently there can be some variations on different units.
