Calling air suspension experts

That's the most comlete bus air schematic I have ever seen! WOW

I'll stick with the simple stuff!

My head hurts now!

I'm psychic?
Not really, I read your blog the other day and saw the entry about your start issues!!

That was where I was headed.  The intermittent no-start has been an ongoing saga & the problem with intermittent failures is you never can be sure you have solved them until enough time has passed that you kind of forget that it ever was a problem.  One thing is for sure - an intermittent problem will never occur when you have time to deal with it - this one has manifest itself at check-in, rest areas and fuel pumps but every time when I have been parked somewhere that I could have worked on it the bus has started just fine.  I've even gone a whole week starting it 3 or 4 times per day with never a failure and then pulled into a campground and had to use the rear start switch.  On the positive side I now have a new brass hinge on the cover for the rear panel and I have replaced pretty well all the individual components between the key and the starter, my battery terminals and cables are really clean and well greased and my crossover connection between the coach and house is working well with a disconnect toggle in it.

Stevet,

Thank you!

Update:

Frenchy-bus parts department shipped my relays to Nipawin despite clear instructions to ship them to Regina. 

Him: "you mean you don't want them shipped to Nipawin?"
Me: "NO - ship them to REGINA"
Him: "OK"

So they sat on the shelf in the bus depot in Nipawin for who knows how long.  The very day that Prevost told me they had traced them and they were in Toronto a good friend phoned from Nipawin to say he had seen them on the shelf at the bus depot.  He picked them up and shipped them to meet up with us and yesterday I got them installed.  Then today I fixed air leaks.  I can see why nobody uses copper air brake line anymore.  What a colossal PITA it is.  I had to switch some of the lines to Synflex after I wrecked some of the copper getting it out but I wish I had switched everything.  None of the Synflex connections leaked and literally every single one of the 1/4" copper lines leaked.  They end up having to be so tight that I was afraid I was going to break the fittings before they quit leaking.

One more reason I don't have a Prevost....... I can't afford an engineer to explain the air system to me!!
