[Latitude 28]

Hello Gurus,
We are on a trip in Sherman TX.  Went to leave this morning and the front of the coach would not raise to travel height.  Did a little t/s and will try to articulate what is going on:

• With the engine running and air pressure at 120 HWH travel light on the front has not come up...back is fine.
  
• Air is escaping the front six pack manifold exhaust port.
  
• When I try to manually raise the coach I can hear the solenoid activate and more air escape by a factor of two.....coach will not raise.
  
• In the travel mode, I could not locate the magnetized travel solenoids.
  
• When I activate the dump switch I don't hear any change in the air leak.
  

Here are the questions; 

• I looked for a HWH manifold picture identifying the different solenoids in my books and could not find one.....does anyone have a diagram?
  
• On the front six pack which two valves should be energized in the travel mode?
  
• which one of the valves is the dump valve?
  

We are safe in a RV park so not on the side of the road situation.

Thank you in advance for the help!
