we were having this same problem of the compressor turning on and then immediately off as soon as the robot was enabled. now the compressor does not turn on at all. after reading several other posts i noticed that our relay leds on our digital side car are not lighting up and the led on our spike stays orange, it has never changed colors, i've tried fliping the pwm cable around but that seems to not have made any difference. we are using the example vi from labview to try to run this compressor and cylinder. does any one have any suggestions on how to get the relay to start working?
