Matt,
Bill's advice is good.
Start the coach & air up with the 110V air compressor off. When air system is full shut off the engine. Monitor & record readings from both needles of the brake gauge and the auxiliary air gauge (supply). Record how long it takes your auxiliary air gauge to drop 10 psi from full all the way down to zero. When your auxiliary gauge hits zero what do the needles of the brake gauge read? Report back the results.
With the engine off, turn on the 110V air compressor, record at what the auxiliary air pressure gauge reads when the 120V air compressor starts and shuts off. Also time how long the 120V air compressor runs between starting & stopping. Report back the results.
Have you built a leak down tester to determine whether the components you cited are leaking? A leak down tester is the only tool that will 100% positive tell you whether or not the component is leaking AND allow you to measure the amount it is leaking.
