all of that is connected properly, at least as far as the diagram and black to black etc. The issue is likely going to be found to be a programming one - however, i'll describe the problem as it stands and get some help!

the spike has a light - it lights up. 12V incoming to the spike, none going out of the spike. When compressor is just hooked up to a battery, it does blow air. when hooked up to the spike, nothing.

We're stuck and can't figure it out - the programmer claims the code is set to enable compressor when buttons are pushed, but we push the buttons and nothing happens.

thanks in advance!
