Need some help,
I went during the weekend to start the coach as I always do and this time the Low Air light stayed on after starting it, I thought it might be that needed to build pressure but after the needles reach normal pressure the light stayed on anyway, I even left the generator and the engine running for almost 45 minutes and nothing changed. I stopped both engines and started looking for air leaks but can't hear anything, I also know that I might have an air leak and might not hear it easily so wondering if I should keep looking or if this could be a sensor that is failing as I don't seem to have major issues with air pressure (after I turned the engines off and for 30 minutes didn't have a loss of pressure).
Any help will be appreciated.
