Thank you for your reply. On this bus there are two air gauges. One for the brakes and one that says Air supply. The gauge for the brakes reads 120 lb, but the air supply gauge reads zero.
I've done a little bit of research in the very minimal time that I have. I understand there are three air compressors on board. I have not been able to supply 110 volts to the bus for that air compressor to work. And I'm not even sure where the 12 volt air compressor is to see if it's working. But from what I understand, it really doesn't matter. The engine compressor should supply air for all air systems that require the bus to move I.e the brakes and the airbags. Am I correct with that?
The PPV valve makes sense. Any idea where I might find it? I know all the buses are built differently, but I'm hoping that they're somewhat in the similar area to one another. What would I check for exactly?
