Oh yeah, this is going to be extremely useful. Thanks for posting this, as I'm chasing more leaks after this last cold spell.
I changed the file as I realized I called the Thomas 120VAC Compressor the Engine Compressor. I also repaired some spacing issue.
Thank you, the forum needs info on the late model coaches. They are so different than all the coaches that came before.
It's a work in progress which will eventually add page(s) for levelling and load transfer. The PPV valves are leaking or at least something is since the main tanks won't hold air, I haven't looked for those valves yet. That system doesn't matter much since it doesn't affect me when camping. Finding the dash air refrigerant leak is more pressing.
thank you,
i have worked on a couple of valid leveling system newells and noticed they do not have ping tanks for the airbags like my 02 does. (did because richard and i replumbed mine out of the system because it was causing my left front to drop).
looks like your diagram confirms what i have seen.
i also noticed on an 07 i had here at my place that we worked on that the rear airbags went up much faster than on my 02 and what i have seen in all the other hwh system coaches.
this is probably not the case for a discussion on this but i wanted to say thanks and make a few observations.
thanks again
tom
Good job, I'll take a closer look and compare it to our 2015 #1524.
Thanks!
Updated to include color code and rear manifold additions
Updated again. Now 2 pages & includes the Tag Axle Increase Load diagram but is missing the destination for 3 lines
Updated the diagrams in the first post to show more detail
