Jan,

Basically, you have two separate parts to this system.

First, you have the pump and pressure switch.

Second, you have the solenoid valves (the pic in your first post). These are activated with the up/down switch.

Looking at the pic of the solenoid valves, there are two pairs of wires on the upper part (just above the red "block", which is the valve body). These wires go to the up and down solenoid valves, and receive power from the up/down switch.

At the compressor, remove the two red wires from the pressure switch and temporarily connect them together (just a few seconds). The compressor should run. As Steeler mentioned, don't let the compressor run too long, as bad things could happen. If the compressor runs, then the pressure switch is bad. The pressure switch is most likely the problem.
