picked up a cheap used compressor today. there is a dayton 2hp single phase motor on it, doubtful if it is original to the compressor. in the wire connection box on the side of the motor there is a thermal reset button that has 3 wires on the back of the switch. One of the three wires is disconnected and wrapped in tape and the only other open wire is the ground from the power cord via the pressure switch. my question is does anyone know where the third wire should go? one of the other two wires on the switch go to the motor, and the other to the bundle of wires connected with a wire nut that is connected to the incoming power from the pressure switch. I assume the ground wire should be connected to the box containing these wires? but the loose wire from the thermal button???????? I know these pics aren't the best but its the best I could get with the light available. Any help is greatly appreciated.

I believe I figured it out. After wiping off all the dust, it appears as though the ID markings on the wires are still there. I should be able to follow the diagram on the name plate and wire properly. It seems as though the previous owner knew even less than me and had it wired incorrectly.

and then sold it when it didn’t wok?seems as though the previous owner knew even less than me and had it wired incorrectly.
Looks that way. I think he said he sorta inherited it. Either way changing a few wires took 2 minutes and it runs. A little cleaning and a new pressure switch and it's good to go.and then sold it when it didn’t wok
