Default 2000 express 3500 A/C issue

Can anyone verify that the computer cycles the compressor as needed to avoid and over pressure condition? I've troubleshoot my issue and I have the correct signals from the hi and low switches to the computer but the output from the computer to the ac relay doesn't go low to start the system...if i manually force that signal low, the system starts and cools great but the compressor never switches off...Im assuming the computer cycles this line periodically to avoid an over pressure condition...
Just trying to eliminate everything else before I replace the computer
Any help???
