I have just spent the best part of an hour fault finding on one of the other wall boxes, this one is a 3WA 200 selection. I dropped lucky and found a contact with the case on one of the wires running to the "Dual Pricing Unit". Something is still wrong as it seems to be on freeplay, but it is sending pulses.

Same as with the other wallbox, doesn't work with PC Play, so I assume my power source is the problem Project back on hold until I can find a workable solution.

Anyone got any tips?

Cheers

Cris.
