I have a 1996 EZ Path II lathe. I bought it at an auction. Works great except for the coolant. When I turn the coolant on the pump motor does not turn on. The small pump unit has a quick disconnet from the lathe. If I unplug the disconnet and check the pins with my volt meter after turning the coolant on, I only get 1.5-2VAC. Is there a relay or switch that is not working correctly? Any ideas how to fix it?
