Hi everyone, new to the site, I recently purchased a central machinery lathe, (dsl1237gh) the previous owner replaced the original motor with a 1.5hp Baldor, somewhere along the way when he wired it, there were a few missed connections, I worked thru most of it, got lathe running but will not reverse and jog switch pops breaker when engaged, I am wondering if anyone would happen to have a manual or any insight on this model, thanks.

240 volts supply correct? Can you post a picture of your motor terminal block? The problem is likely there MS

We should check the jog problem first. Shut off the breaker.
Disconnect the motor, tape the wires, re-power and see if the jog still pops the breaker. If so then the contactors are miswired
We'll need to fix that first before reconnecting the motor

Yes, just jog with motor disconnected, wires taped off
Shoot a pic of the whole control box please, try to fill the frame, but keep in focus
I see at least one error on the bottom contactor terminal row- maybe two
I'm concerned one of the contactors is faulty and the PO was trying
to bypass it- shouldn't have needed to mess with those for motor replacement
Do you own a multimeter of some kind? Picture if you have one
Doesn't need to be expensive

Ok that's encouraging
It looks to me that the purple wire is wrong, and there should be wires on the "V" lower terminals of both contactors
Shoot a shot of the whole contactor box, so I can see all the contactor terminals
At the motor it should connect like so: (motor set for high volt)
U and V from the box should go to 1 and 4 of the motor
6 of motor should go to M6 from box (6 of motor disconnected from 1, connected only to M6)
May not work but you can try it
I suspect we will have to revisit the contactors
