I'll throw my gauges back on later to verify pressures & temps and top up if need be.

I have a 1998 dodge 3500. The high pressure side is about 200 and the low side is about 40. When the compressor cuts in it takes the low side down to about 20 then cuts out (which takes less than 10 sec.). I replaced the cycle switch (on top of the dryer) and it made no difference. When I unplug the switch and put a jumper wire across the plug the system runs constantly and cools well.The low side stays about 15 lbs. Any ideas ?
