Now, I connected the unplugged Raduino to the USB socket of my computer, and it lit up. Connecting the two encoder wires only, black & brown, has no effect when the encoder is turned.? This is the case whether or not the centre pin is earthed to the Raduino ground. I confirm it reads LSB A 7.150 .

Hi Geoff,
I am at a loss as to what could be the reason for your problem then.
The thing I would do if I was in that situation would be to go bare bone: remove the Raduino from the main board and power it by connecting a mini USB cable to a computer or phone charger, plug in the control port with only the two encoder cables connected.
If that does not work, I can make a special test program to only display the analogue inputs values, if you can/want to program the Raduino.
I can do that tomorrow morning as it is getting late here in VK land.
