Another compressor problem

[bubblerboy64]

Ok, Where is the governor? You guys gotta remember I am pretty much
stupid on this stuff. The only thing on the compressor is what
appears to be a small filter housing on right side of the thing
looking into the engine bay from the front of the bus. Something
obviously opens and or controls the compressor because when it is
functioning I can hear it cycle on and off.
