Dear Atmashere and Tpsonic, I am thankful for the advice but,alas,I am not capable to move in the opposite direction at the same time. Something that according to physics and logic is not possible. So I still have no idea
what to connect to pin 1: according to Atmasphere both(the shield as well as the ground wire);according to Tpsonic only the ground wire. But I still dont know which of all
are connected to the arm-mass.The shield or the ground-wire or both? Then,you see,I will know what to connect to
pin 1.
BTW I think I should look for a different hobby.
Regards,
