Have the motor turned off. 
Have the printer and keyboard in series 
  in the local loop, with loop current flowing. 
Turn the motor by hand (as I recall, it goes 
  clockwise looking at the motor fan); 
  turn enough to be sure everything on the 
  main shaft turns freely and doesn't jam. 
Press the R key on the keyboard; 
Rotate the motor by hand; 
The keyboard contacts will open and close 
  the local loop, and the selector magnets 
  will respond to the open and close (space 
  and mark) conditions - but in 'slow motion'! 
Continue rotating the motor by hand and 
  watch how the horizontal selector bars in the 
  front of the typing unit move up and down to 
  set up the code for R; 
If all sets up correctly, eventually the typebar 
  bail (underneath) should snag the R typebar 
  and try to flip it up to print (it won't flip with 
  much power because you are doing 'slow motion' 
If the R typebar does try to 'flip' then all is good; 
Repeat above for the Y key on the keyboard. 

If both work correctly, it's time to turn on the 
motor and try it in 'real time' ...   :))
