My 2 cents worth:
Unplug the machine from the wall (with the 
temporary jumper removed), Flip power switch to 
OFF. Un power any loop supply if connected. 
Connect one ohmmeter lead to the point on the 
power switch where you had previously connected 
one end of the temporary jumper wire. Now using 
the other ohmmeter lead go looking for the 
terminal,contact etc on the machine that shows 0 
ohm continuity to see where the switch wire goes. 
Keep going if continuity goes through any 
switches, jumpered terminals etc until you find 
the open circuit on the way to the below 
mentioned motor contact. You should find an open 
before you get to the motor,.i.e. no additional 
terminal, switch or contact etc showing continuity.

If not obvious where the problem open is, you can 
remove the motor, clip one ohmmeter lead to below 
mentioned motor contact and start probing for 0 
ohm continuity with the other ohmmeter lead as 
before. Should lead you to the same area where your previous check stopped. .

Hope this helps.

  >UPDATE: Just placed a temporary jumper from 
the power switch, on the switched side, directly 
to the motor contact (#16 on the schematic 
we’re referring to) on the block under the base 
behind the keyboard bay.  Flipped

 >the switch to ON and VOILA, THE MOTOR STARTED! 
As for a safety cut out to defeat power to motor 
when typing unit and/or keyboard are removed, none found.  T
