i have been trying to figure out where my small leak is that causes my front drivers side airbag to slowly go down.  

so, i have been playing and tracing things for about a week.  

i raised the coach all the way up using the leveling system and then used my new 22ton jackstands to keep the front up.  i lowered the coach all the way down...i am too big to get to the front 6 pack without it being raised up.  

i identified and verified the location of each solenoid valve.  the same for the air lines coming in and out of the six pack.  what really baffled me for a few days is that someone had written on the yellow air lines what they were in magic marker.....and they were WRONG.  

i used the test rig to check pressures.  i did it a little different than richard outlines.  i found the lines that went to the ping tank that feeds the airbags.  i connected one side of the test gauge to the drivers side front airbag and the other side of the gauge to my shop air.  then i used the valve on the gauge to air the bag up to 100 psi and made a note of time.  it leaked down 18 psi in 11 hours.  not sure that is alot or not for sure.  

i sprayed alot of kids bubbles on the airbag and as much of anything else i could see.  no bubbles.  

while i was under there, i used a magic marker to label the six pack and used a label maker to label each wire.  i marked the airlines (correctly) with magic marker as well.  

i also took all six valves out and rebuilt them using my rebuild kit.  

i aired everything back up, sprayed some more bubbles on everything and didnt see anything.  

i measured the coach height at the front and back wheelwells and made a log and will check in the morning.
