The Aux 120v compressor feeds the entire air system, just as the engine mounted air compressor does. The engine air compressor has many times the air flow of the aux. compressor. It could be one large leak but it is likely multiple smaller leaks. You need to isolate the various systems from each other to really track down the leak. I have a set of 6 videos that memorialize a presentation Richard Entrekin gave in Foley, Alabama back in 2019 discussing how the air system works on a Newell. If you haven't viewed those, please do.
