yes, forgot that one.
So we have contactors that work with no motor, we have a motor that works connected directly to power, but a dead short when the two are connected to each other.

Can you confirm that you removed the jumpers that were put on when testing the motor separately before you reconnected it to the machine?
Yes, I disconnected jumpers. Went out this morning and disconnected the motor wires from the lathe and hooked it up to a separate cord. The motor runs fine. plugged it in and out several times.I can hear the centrifugal switch close. Rechecked voltages on post # 19 z1-z2 240 volts forward and reverse u1-v2 240 volts forward and reverse. Checked all contactors, all good. Just curios what is the black contactor thing with the dial on it in the electrical box .The large wires have continuity top to bottom? Here is how I wired the motor in the pic.The other pic shows how I wired the forward/reverse switch.

I see an error in the pic- do you? Check again
Well that explains it
That black thing is an overload protector for the motor, will have continuity unless it trips
v2- u2 ?
ok good to know.
Close, check your connections compared to Marks diagram in post #13
