How does evryone have there compressor wired in??

i got a compressor from airbagit.com/chasis tech its the dc 7500 i believe. I have a power wire from battery goin to circuit breaker then circuit breaker to solenoid, solenoid has power wire goin to compressor the wire from the pressure switch is wired in to it also. Nothing turns on.. the only time my compressor turns on is when i touch the power wire to the compressor power wire...?? i need help wiring this thing up.. And no i dont want a schematic.. i have them and they dont work.. How does everyone have theres wired up... Pics would be good also..

Do you have power from the pressure switch to turn the solenoid on and off? If you could draw a diagram and post it that would help a lot.

Maybe take a pic of your solenoid. How many terminals does the solenoid have? Is the solenoid mount down and grounded?

the way i had mine was power wire going from battery to solenoid then to the compressor, compressor grounded,1 smaller wire going from my ign to the solenoid ign post,the ground post i ran a wire out and back to the psi switch then from the psi switch to the frame

SOUNDS LIKE A GOOD WAY TO DO IT

Fixed it for ya

Your pressure switch is wired wrong. Where you have the pressure switch grounded should be a switched 12 volt source(either an ignition wire or a toggle switch). The other side of the solenoid should be grounded. I drew a quick diagram, try it this way and see how it works.

it only has three prongs... i got one that has 4.. it has a S and I which i dont know what they stand for... any help is great..
