compressor runs until it reaches full pressure, motor stops. air releases from place where black tube goes into the swich( not the pressure release valve). pressure drops until it kicks back on, will not hold air. keeps on cycling on and of?

- I believe it is a faulty check valve, i pulled it out and it seems to be faulty.
but i cant find a replacement one that looks like it would work.
I believe you have a faulty pressure switch. The black hose reports to the switch what the pressure is and either starts or stops the compressor through the switch. Air is bleeding out of the hose ...causing short cycling ... for some reason. Fix the leak - fix your problem

- Hmmm ... not sure there is a check valve. I guess it could be ...
The connection I am speaking about has to be open to the pressure vessel so it will know when the pressure goes below the "turn on" setting so the motor will start. The "plumbing" is otherwise solid?
There is a over pressure relief valve that could be leaking (failed to close properly after it was forced open) Or maybe it is set lower than it should be set. Don't adjust it to a higher pressure!
Check the pressure relief and the "dump" valve. The dump valve lets the air out of the cylender that was at or near TDC (has lots of pressure in it ready to go to the tank but didnt get out) when the switch reached max pressure and shut the motor off. Purpose of that dump valve is to make it easy for the motor to restart when it is time (when the pressure goes down).
Let me know what you find out.
