Anyone know where the air source selector valve is located? When I start the Detroit motor the air compressor only fills the air brake system and won't start filling the air supply system until I run the onboard compressor and bring the air supply system up to 70+ pounds. After that both air systems are filled and maintained by the main compressor mounted on the Detroit motor.
