I have had a good look at the motor but there is no plate or information on it. I was told it had been rewound recently to single phase (at vast expense). The motor is big! 25cm across!What size motor is the starter protecting? looks like the purple wire is a short to remove the overload contacts from the circuit. Possibly the overload was set too weak or it has failed. The coil voltage is usually written on the coil of this unit.
IE The motor has overloaded and the overload would not reset or it was set too low causing constant overloading. Therefore somebody "fixed it" in a dangerous way by adding the purple link.
Please check the motor size to see what the full load amps are or post a photo of the plate.
ps did you notice the nipped cable?

I have installed another starter switch, I had in stock. A normal single phase unit, the same as on my single phase four post car lift. But the lathe will not run using that switch. So I don't know.
