Well I m sure you are very frustrated especially with impending trip fast approaching. The one schematic you posted for the whole coach is very small and impossible to read, but I find the Thor one line diagrams not particularly useful anyway......want you to go to a dealer of course. Since your aux start is actually working the other approach is to list all the systems that are not working when engine is running and coach and chassis switches are on. Maybe there is some common electrical connector/connection that would account for that group failure. It would be nice to have a fully documented schematic but not many of us has that.
