Does it turn on at all? Get the compressor and hook it directly to the battery and make sure its still functional.

What gauges are you using? Analog or digital. Could be reading wrong pressure.

Make sure the pins on the switches and connectors are not bent. I had an issue where the compressor wouldent turn off past the set psi. Pins were bent and not connected.
