I have just acquired a Monarch C lathe 1943, a rather nice machine - but cannot see what voltage it has been configured too in order to power it up to test it. Plates and tags are occluded. There is a small tag but I can only make out the numbers 220 240 so it does look like two choices. The motor,when viewed at the back of the lathe, has 3 wires coming out of it. They are all black. No 4th wire. There are no leg numbers on them. I cannot see a usual terminal block with Legs 1-3 and then a set of jumper terminals for the voltage setting. Two of the wires go off to the on/off box at the front of the lathe which looks original. The 3rd goes into the conduit so it looks like one leg bypasses switching or maybe it went to a disconnect but them when you switched on would this mean one phase winding would be hot before switching the lathe on at the front control. I am puzzled.
Anyone able to tell me anything about this?
Am I looking in the wrong place for the legs and terminal block?
Anyone have a wiring diagram?
Thanks,
Dave
