Question about Air & Gas Compressors
I got a 25 gallon craftsman air compressor pressure switch was discontinued by sears pressure switch was toast now i got a new pressure switch from grainger just like one on compressor (part no. 65013-005-50G) made by Square D. now wiring on the (sears) pressure switch has Line positive and negative terminals and also Motor positive and negative terminals, there is also a ground. the new switch is labled different there are T1 & T2 terminals and then there are L1 and L2 terminals does anyone have any idea how this is wired? do i connect Line pos & neg to L1 & L2 and Motor pos & neg to T1 & T2 or what?
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

Im trying to hook up a 115v line into my 100-140psi switch i have a similar problem, when i hook up the power line to the "line terminal" and the the motor wires to the "motor" terminals all i get is a buzzing sound but no power. But if i connect the power straight to the motor everything works. is it the switch?
