I have another significant leak in my air system and am unable to locate it.  I have an appointment in 3 weeks to resolve the issue but I’m trying to put in place a temporary fix with an auxiliary compressor.  Right now I have all air turned off as the Thomas compressors were coming on in less than 5 minutes and frequently shutting down due to excessive run time.  I purchased an appropriate compressor and think I have it hooked up properly but I’m getting no air to the coach.  Would really like to be able to operate the door! I can live with slightly out of level for the time being. I have attached pictures and would appreciate any ideas!

The compressor shows 120 psi and the gauge in the picture shows the same.  Is there another cutoff I’m missing? 

Thanks!
