I also noticed that on the tag axles Moho's, the Air bags will deflate once the tag axles gets pulled off the ground by the leveling system. I assume this to keep the rig leveled, in case the bags deflate slowly?
Thanks for your thoughts
Several things could be the cause.
The air supply line, before the check valve, could have a leak.
The pressure switch could be bad.
The compressor might be worn out if it cannot bring the pressure up to the pressure switch rating.
If the tag axle is off the ground, the air pressure in the bags, will drop to minimum, as the leveling valve is sensing that the tag axle is too high.
