I have a Clausing surface grinder that I can't get the hyd. motor, coolant motor or wheel motor to come on. The contactors are ok and when you push them in manually everything works.
When you press the "on" button on the control next to each motor you want on, nothing happens. I've checked all switches, transformers, fuses, etc. No power to the buttons. Does the chuck have to be seen by the control as being on? The hyd. motor contactor has power to it and as long as the main " power on" button on the control is off, you can get the motor to start by manually pushing in the contactor. If you press the green "on" button, as soon as you push in the hyd. motor contactor the power drops out from the contactor. ?????????????

I didn't notice any forums for Clausing??
