Norton W/S 6" Type CTU Electrical Schematic Needed

We recently purchased a Norton W/S 6" Type CTU in an auction. We are now powered and there is no vibration in any bearing or motor, we replaced the belts, changed and filled the various oils and pretty much understand the semi automatic operation. However, we are having a small control issue between the work head operation and the coolant pump start. We have tried to abandon the coolant pump wiring at the coolant pump and simply feed it from a separate disconnect and that operates the coolant pump. But we are wondering if we have somehow interrupted the control circuit for the work head as that does not want to turn on now that we have taken the pump power off the circuit.

What we really need is the electrical schematic for this machine so we can trouble shoot. A local machine dealer told me that based on the serial number, this machine was built under Warner & Swasey in about 1972. I checked the Industrial Manual website for this information and came up empty. Does anyone have a copy of any electrical drawings for this model? Thanks!
