Thanks for the reply.....I checked all fittings for oil stains/residue & could not find any but psi on low side was low...just over 20 psi with air on max & hi. I added Napa r-134 plus it has the oil & ink & now low side psi is around 42-43 & compressor now go's on & stays on. now I wait to see any ink stains to find leak.. I will keep all of AF updated...So I now know the compressor still works
