The motor should have 5 wires coming out of it. One for ground, two for field and two for armature. Take out a brush. With your ohm meter find the two wires with resistance. Sorry, can’t remember what it should be? ~400? Mark the wires "field". Put the brush back in. Then two more wires will have resistance "arm". ~7? The last wire should be ground to the motor case. ~0. The other wires should have infinity to case ground. Again sorry, I cannot recall the typical found resistance. But hopefully you get the idea of what kinda resistance range you want to look for…Good Luck, Dave.
OK I did this just now. The field wires are reading 583. The to arm wires are reading 1.7 to 2 ohms. There isn't a 5th wire. I assume its just grounded inside the motor. The entire enclosure is grounded by the incoming power ground to a screw.
