Connect your gauge to the low side port (next to the big can) with engine off and stone cold. Do this first thing in the morning or late at night. The pressure should read somewhere between 80 to 100 psi according to ambient temp. If it reads lower than those, total system charge is low.

Low charge could be the cause of your rapid compressor cycling.
