No sworries Ken. Bob and I have been through this a number of times over the years.
Slotbob:
As I suspected, the terminal in question, no longer hidden by tape, is not snipped the same as the other, ergo you cant use our mirror image terminal trick to simply power each lane.
We gotta add lib here, in order to get Wiliy going! Im pretty sure I'm on it, but a dyslexia check on me sure wouldnt hurt.

To fix:
Number pin sets pictured 1-6, top to bottom.
#1 gets power supply
#2 is not used
#3 gets a controller
#4 is not used
#5 gets a power supply
#6 gets a controller
Note: Ordinarily the common shunts are cut between the inside and outside lanes. We do this so we dont have an open shunt flapping around underneath, requiring insulation, and less intuitive wiring to be sorted. Spot welded shunts are more reliable when they are short/firm.
Please let us know how you progress Willy
