How many wires? Two wire will not cause it to run opposite direction. By the way, the compressor will not care which way it rotates but the motor may not like running backwards.
If there is a motor connection option for rev rot, high/low voltage, then it is an issue but if its straight out single voltage and non reversible, then who observes which way a motor rotates and notices the rotation has reversed?
SOURCE: need help wiring new pressure switch for craftsman air compressor
Assuming that you are wiring for 115v. Lets start with the ground. The cord that attaches to the wall outlet will have three wires, green, black , and white. Insert the cord thru one of the openings of the pressure switch and attach the green wire to the ground screw. Next look very closely at the contacts and notice that they are arrainged in pairs. There is a small brass bar with two contacts that completes the circuit for each line. Start with L1 and attach white wire from cord, then attach white wire from motor to the screw terminal that small brass bar bridges to (should be T1). Next attach black wire from cord to L2 and black wire from motor to remining screw. Remember that the small brass bar with two contacts is the bridge and simply connects white to white and black to black. Enjoy

Dear csdamman,
There is a valve called the spill-valve. It is often called the control valve. This valve activates the micro-switch. When the gun is released, pressure builds up and compresses this spill valve. At the same time it puts off the micro-switch. This will then stop the machine. Now when the spill valve is faulty it cannot hold compreesion under pressure so it starts de-compressing and starts the machine again. This goes on in a cycle as you explained. So you have to change the spill valve. If the spill valve that operates the micro-switch is part of the upper head,...then the whole head must be renewed. Myself I rarely service Spill Valves. The best thing is to renew it. From your explanation it seems that you did not take notice of this Spill-Valve. Infact when you mentioned Pressure Switch, I do not know if you are refering to the spill valve. If you are....then saying that the Pressure Switch moves and operates freely, does not mean that it is OK.
In certain machines in the outlet...there is a small valve, coloured black and red or green and yellow. This sometimes when faulty, it gives the fault you mentioned. Sometimes an inlet valve gives the fault you mentioned. But from my expirience it is most of the time that the Spill-Valve is the fault.
Regards,
Fulltech.

Pressure switch has gone bad and needs to be replaced. Part runs around $25. Go online and put in model number, pressure switch. You will find companies that sell replacement parts. I had to replace mind, it did the same thing.
Testimonial: "Thanks for help, many appreciated."
SOURCE: I have a PUMA air compressor that has been running
If you remove the fan belt and the motor runs without a load,
one of your motor capacitors is bad. some motors take one
capacitor, some take two. the capacitor is what helps the
the motor give that extra torque to run the compressor pump.
good luck!

Outside Air Conditioner Unit: Fan Spinning in Reverse Recently I replaced the contact relay and the capacitor (dual capacitor) on my 2.5 ton Payne outside unit. I thought that I wired everything on to the new capacitor correctly by following the wiring on the old capacitor. However, when turning on the unit, the fan on the outside unit spun counterclockwise. The unit was Sucking In Air rather than blowing it out, which is bad for the unit. Solution: Originally on my unit the Brown Fan wire went to the Fan position on the old capacitor. The other Light Colored Yellow Fan wire went to the Common position on the old capacitor. However, wiring it the same way on the new capacitor reversed the rotation of the fan, thereby causing the unit to **** In Air. By reversing the Fan Wires on the new capacitor, the fan spun clockwise and the air was blowing out of the unit. On the new capacitor the Light Colored Yellow Fan wire was this time connected to the Fan position of the new capacitor and the Brown Fan wire was connected to the Common position of the new capacitor. Note: If your compressor has a delay in starting, you may want to consider adding a hard start capacitor. This has two Black wires that are wired to the Compressor position of the capacitor and the Common position of the capacitor. Wiring order does not matter. Crabman
