Parts arrived from RRD yesterday. I got smart-assed and only plugged the new Ramps board in, re-using my old Arduino. Works just like before, I.E. can't move Z without the problem being that Y now only moves in one direction. So time to use both new parts and report back.
Thought of two more things to try before I swap parts:
1. Powered everything off and restarted, Y moves OK, moved Z, broke Y, moved Z again in opposite direction (as previously suggested by cvoinescu), still doesn't work.
2. Swapped X and Y wires, shut everything off and repeated tests. Still breaks an axis, but now it is the X axis, Y works OK.
I think this proves it is in the Ramps/Arduino, not my Y wire.
Changing out to both new boards, I will report back.
