It looks like something on the other end of that riser cable was shorted out to a ground. Those first three pads/wires on the nearest side are 12V power, two of the three on the other side are also 12V. The 4th pad in on either side is a ground, none of those 12V pads can touch any of the ground pads or you'll see what you've got there.

There are no different risers, they all do the same thing basically. You may have just got a defective one.
