Check to see if your Aux. Battery Switch is on. I had the same problem your having and that was my problem after hours of checking. Put a volt meter on you house batterys and if they are charged.If so I would bet this is your problem. Good Luck.

On my rig there are three solenoid switches in the battery compartment. Two are identical, and they serve to isolate the batteries for storage (one for the two coach batteries and one for the chassis battery). The third solenoid functions to cross-connect the 12v systems for an emergency start.
If the emergency start button on the dash restores the coach 12v power, you have a faulty isolation solenoid that is stuck in the storage mode.
You didn't mention whether the shore power provided 12v functions.
Anyway, HTH.

In my experience you're back to the isolation solenoid. Look to see whether you have a panel labelled IntelliTec, which in my case has two rocker switched on it.
You might try cycling the storage switch for the coach battery several times to see whether the solenoid will catch on the "Use" side. Mine sometimes doesn't connect on the chassis battery, and this has worked.
If you have a bad solenoid, I've seen them on eBay for $58. IntelliTec part number 355-721 is what I have in my repair notes.
Best of luck!

Locate your battery disconnect relays. Use a test light or meter to see if battery power is on battery side, next cycle the disconnect with the switch(have helper do this while you listen for the relay to operate), check the coach side of the relay for battery power(shorepower disconnected). Should have the same voltage on each side if it is operating.
Look around the same are for a small DC circuit breaker. It could be tripped as some have a small button to reset. Others are not resetavble and must be replaced. Check both terminals of circuit breaker for battery voltage(shorepower disconnected)

Running the engine alternater does not bypass the 12V disconnect switch to the coach 12V system
