No, no. The compressor is powered properly, from the breaker panel. The pressure switch, that turns off at 115psi, and turns on at 95psi is wired to the RC. Then, a signal goes out the relay output to the spike.

In the interest of clarification, here is a simplified picture of our wiring


Not pictured: Breaker Panel, fuses, etc. Assume that the compressor receives it's power properly.

That won't work. The RC digital inputs have an internal pullup to 5 volts, so you need to connect switches between the signal and ground pins.
I'll pass that on. So we shouldn't have all three wires connected, only 2?
