So, you haven't had the lathe running at all yet? Or just running in one direction?
I think I see what you need to do at the motor end- You want to run it on 220 volts correct?

I have run the lathe. Depending on where the wires that go into the motor itself are positioned in relation to the four numbered wires in the box it will either 1) run same direction regardless of lever position or 2)one direction when pulling the lever up and no rotation when pushing the lever down. A relay will click in this scenario but no motor movement.
And yes I would like it to run on 220v and when I first got it I wired it to run on 110 and it didn’t have enough power to make a decent cut.

OK I understand- give me a few minutes and I'll post something for you

Try this: For 220 volts operation
(Disconnect the #1 white wire and insulate the lug with tape or heat shrink tubing)
Let me know if you can't get the wires to reach- we can move things around
Swap B5 and B6 if required to invert rotation

I appreciate it thank you. I’ll go give this a try and see what happens.
