We just installed the new EMI software (SX upgrade) and put our pentium motherboard in and a new flat screen monitor.

Now - there is a loose wire on the "spindle enable/start switch" about 2" long, looks like a jumper since it wont easily reach any other switches. Any of you know where this goes? Cant track it down from the schematics.

We cannot get the machine to start a program, or start the spindle........probably due to this wire.

I am guessing but there are two sides to this switch. The purpose being to enable the forward or reverse contactor (if you are in low or high gear). It is cost effective to run the power to one side of the switch and jumper it to the other side. Then there should be one return wire from EACH side of the switch. Therefore see which is the hot wire per a meter or the wiring diagram and that should be jumpered to power the other side.
