I was having trouble with controlling the spindle rpm on my 1965 modular 10ee. So figuring it must be the max speed pot, ordered a new one from Monarch. After taking a good look at the pot still in the lathe, decided to look into replacing the six strand cable that runs from the pot to the module.
Opened up the module cover, and found that the six wires from the speed pot were dis-connected
What makes this even more head scratching, I had spindle rpm control from basically zero rpm to approx 1000 rpm even with this pot not connected. Above this approx 1000 rpm the spindle would accelerate un-controlled until it shut itself down.
Is there something else connected to the speed control knob that controls spindle rpm? Sure does not seem to be, but something was controlling slower rpm. I have been using it this way for over 6 months without any odd quirks except the limited speed control
