Hi guys, I've cleaned up the head assembly and associated switches, put everything back in and tested but the original fault still persists. At the moment I think the switch main switch 67 is open when it should be closed and closed when it should be open but maybe I'm misinterpreting the manual.

T.12 Head Test in the manual says - "The display will show the status of the motor (MR=ON or MR=OFF) and the current, if any, head switch (SW=) number that is closed.....In order for the head to rotate and stop properly this switch must be open when on an indentation and closed when not on an indentation".

I assume from the above that the switch should read "ON" when the face plate is at rest and "OFF" when it's rotating. Mine is the opposite. Is anyone able to confirm please.

Picture below is the display when head is at rest
