It's OK I'm having a blonde moment doh.

No worries, I have them all the time  ;D

I have basic overview info re diags, dealer diags pin outs, how pins are numbered etc on my 650GS web site

Onions:
OK

For basic comms checks, it is pins 1, 4, 6 and 10 which are relevant and the GS911 is suggesting no power on pin 10

Check for voltage between pin 4 and  pin 6 with ignition off to confirm that is in place ------------12.2V  with ign On ---11.9V
Check for voltage  between pin 4 and  pin 10 with ignition on to confirm that is in place-----------0V
Plus check continuity of pin 1 back to the Motronic---------------0 ohm and 0V
Confirmed 4 Brown is earthed.

WayneC:
There is the first problem, there is no power on pin 10 when ignition is on hence the warning from GS911

Check there is switched power to the Motronic on the socket to it when ignition is on, I dont have a diagram to check which pin it is

Onions:
So let me see if I have this right - pull plug of Motronic and turn ignition on then see if there is power to one of the plugs?

What if there is?

What if there isn't?

Probably won't get this done today.

Jughead:
It may be a stupid suggestion, but check the sidestand switch.  Is the bike on the centre stand with the sidestand retracted?

I have had some older bikes that will not comm or even start while on the sidestand.
