I rebuilt the piping tubes on my Air Compressor Model 919.176111 and do not remeber how to wire the the wall and motor cord, into the Pressure switch (took to long to fix it). There are three wires to each half of the cord. Black, White and Green Ground. They connect into the Pressure Switch and I need to know how they should be wired stock. The way I have it set, the Compressor never turnes off whether you switch from Auto or Off, or if it hits the maximimum pressure. Any wiring diagrams for this would be of great help.

normally on the preasure switch the green wires are attached to the ground screw in the box.

the terminals on the switch should be marked line or L and motor or M, with 4 terminal screws. the power cord from the wall connects to the line terminals. the power cord from the motor connects to the motor terminals. the whit wires should be on one side of the switch and the black wires on the other side.

That's it. I realized after looking at it closely that there are markings that say line and motor. The only problem I'm having is that there doesn't seem to be ground screws in the switch box. I'll have to look closer. There are these weird clips for each green ground. I also noticed that I had the cut off screw turned to high. After lowering it, it now cuts off at a lower pressure.

Thanks for your help.
