HP-65 card reader problems

Thanks Tony

I have rotated the cam in small increments over a full 360 deg. It does alter the current draw when I apply a voltage across the motor directly as expected. The main issue I think is that I cannot see any real voltage at the motor terminals when Insert a card ? The drive shaft does move axially but won't pull the card and I only measure some 50mv across the motor terminals ?
