Governor diagnosis

[transit360]

Hey all,

If anyone here can explain the function of the governor in
relation to the air dryer specifically that's be great.
I have three lines going to the governor on my Bluebird Q-bus.
One big one, and then two smaller ones. One smaller line goes to the
air dryer on the side of it.
Does one line supply the air, build pressure up to the governed
pressure, then open the other line of the governor to exert an air
force onto the dryer? How does the governor manage to shut the
compressor off?
The reason I ask is b/c my compressor is seemingly constantly
pumping. The air dryer seems to be doing it's job by releasing the
air, and that seems to be the only time I don't hear the compressor
running, right when the air ejects. It's very annoying to have it
pop off the air pressure every 15-20 sec on the interstate. However
the dryer doesn't seem to stick open. It pops off and then hushes
right up, it just seems I keep building and building air pressure
and the only reason I can think of why is b/c the compressor is
never shutting off.

thanks,
Steve
