Hey schuppi!
You are the man. Finally got to check all the pins/wiring out as you suggested and found that all is ok as per continuity. Pin4 however did not have 12V with ignition. I spliced it and got it fed 12V from the ABS module (which is only hot with ignition)
All problems disappeared. Bike is perfect!
Thank you so much for your help.
I wonder though what happened that I dont see 12V switched on Pin4.
