Jon,
I tested the solenoids with the "Richard trick" and found that the travel solenoids are energized in travel mode and not energized otherwise.
This problem was not sudden onset...It has been here for quite a while....but indeed both sides drop together.
One thing that I did not say in the introduction is that this coach has a bunch of miles (240,000 + 15 years old)....Waay past the expected life of an HCV. Could it be that both HCVs are just plain worn out and have some sort of dead spot where they both leak? I think that I would also have to have bad solenoids for the bags to leak even with leaking HCVs. That sounds like a very unlikely coincidence.
I will pull the lines to the travel solenoids next.
Thanks!
