I believe it is #3 caused by #4 way before Nick or I dug into it.  But we are making process.

 

Can anyone add a reasoning for the two 300 ohm resistors in parallel that are part of the motor circuit as shown on the M15 schematics?   I may just jumper around them as a trouble shooting step.  Anyone with any ideas?

Not a 15 guy anymore but there are 4 big issues with all TTY's that can drive you nuts. 

  

1.  Mouse damage. 

  

2.  Congealed grease or oil. 

  

3.  Undocumented mods or wiring changes. 

  

4.  Efforts to fix the machine by someone who has no idea what they are doing.   

  

Not sure which is the worse one, probably #4. 

  

Keep on and you will find the trouble.
