Well, got a weird problem with the power on my 820 lathe. It has a 110v motor and Dayton drum switch. With the motor and switch on the bench it works fine. If I put it on the machine without mounting the switch it works. If I mount it to the machine it trips the breaker. The odd thing is that it worked when I picked it up (but I don’t know how it was wired at the outlet). I assumed it was probably a wire shorted to the switch or frame. I checked for that and found no problem, pinched wire etc. But before I replace all the wiring to and from the switch I thought it might be a good idea to see if someone sees something I did wrong. There are no markings on the motor and it has two red and two black wires coming from the motor, not labeled at all. Do the the two sets of wires need matched up, a certain red and a certain black? It has a single capacitor. The switch itself is a Dayton. I don’t know which wires should be paired or if it matters. Hopefully the wiring diagram makes sense.
