A.o. Smith 312p458 wiring help

[Zoodie81]

Hi all. I'm having issues with an A.O. Smith 1hp dual voltage reversible capacitor start induction run motor. I'm trying to wire the motor to a run switch for the turntable on a John Bean 8950 tire changer. Someone was messing with it before me and did not mark any wires to the switch and all wires coming out of motor are black. I understand how to wire the switch but I am not sure what wires from the motor are the correct ones to go to the switch. There are 6 wires from the motor that go to a terminal board but only four shown on the wiring diagram. I cannot find a diagram online for this motor. Also a red wire and black wire have been taken off the board and run straight from the windings to the drum switch. The motor is from 1998. A.O. Smith's motor division was night out and this motor discontinued. I'll post pictures.

Update, I found that the red and black go to the capacitor so I believe those are the start windings and the other 4 wires are the run windings. The numbering on the board though has me confused are the 3 prongs off L2 1,2 and 3 or are the two outermost ones 1 and 2 and number 3 the next post up which has 4 in between it and the orange wire?

Hey I have the same tire changer and also need a wiring diagram. Any way you could post pics or a diagram?

Since all wires are black, use a multimeter to measure the resistance between the wires. This can help identify the windings and connections.

It's not in the service manual, but here is a general schematic
