Air leak found!

[Xengineguy]

I have had a compressor that cycles too often intermittently. Today was the day to chase the air leak.
This truck will hold air all weekend and then some. I rarely hear the buzzer on this truck. So I made up some fittings
to fill thru the air drier. The leak only made a little noise at 100 psi. at 125 it was easier to hear. Turned out to be the
pack break solenoid! It was leaking air to the actuator then the air returned to the solenoid vent.
I cycled the solenoid several times. No luck. Still leaks. Anyone have an xtra solenoid I could purchase or a part number to google? Thanks and I hope this helps someone in the future.

I am using this solenoid for my fan and for my pac-brake control(2 of them ganged together)… They are from Automationdirect.com, they list the hardware and seal kit and mount brackets along with the valve. Very reasonable price…. Below is my pacbrake valve joined with my fan control valve.
