Re: Compressor Not Starting
Use the LEDs on the DSC and the Spike -- does a little green light come on next to where you have plugged in the cable to the Spike? If so, does the LED on the Spike turn green? The compressor will only run (in the right direction) if both of these are green.

The other thing to check is the voltage between the GND (-) and the SIG pin on the digital input that is connected to the pressure switch. You should be able to see the state of this input using the driver station (as well as the state of the relay output)...
