I know this has been beaten to death and I have searched, believe me. I have a 1943 South Bend lathe that I am trying to restore. The motor is a repulsion start induction type RS single phase motor. I got this lathe in pieces and I'm now trying to get it running so I can at least see what I have before I spend a lot of money making it pretty.
The motor has a 110v power cord that is hooked up with a short lead pigtailed that is just hanging. The drum switch is mounted to the side of the gear train cover. It has 9 terminals, 3 down each side and 3 in the middle. When I got it there were only 3 screws in the middle It's a CH switch. I'll post a crude pic of what wiring I see.
The motor has 4 wires that have no markings but the way it's now wired is two of the 4 wires are tied together to the black wire in the cord with the plug. The other 2 are tied to the black wire to the short cord that is just hanging. the white wires are tied together between the two cords. This wiring looks to have been done many, many years ago and it must have worked until somebody pulled the plug.
The short cord is just long enough to go from where it connects to the motor to where the drum switch is mounted so I assume it went to the switch. Here are some pics and hopefully someone can help me connect the dots. It wouldn't let me post the drawing but there is a pic of the actual wiring. Thanks........
