Welcome to the electrical woes :-)
As I started the tread I'll see what I can offer and apology if this is basic stuff.
1. Possible bad chassis battery. You can do a basic test with a voltmeter or drive to an autoparts store who should be able to test it for you.
2. See if the coach is charging the chassis battery. With shore power off, put a volt meter on the chassis battery. Get the reading and hopefully it is > 12v. Plug in the coach to the shore power and the wait a few minutes for everything to 'get on shore power'. Your volts at the chassis battery should have gone up to >13 if you are getting a charge from the onboard house charger.
If you are getting a chassis battery charge on shore power and your battery is good its a deeper problem of Amp Eaters draining your charge but start with the basics and it wil tell you a lot. If it';s an original battery .. might be time for a new one.
