Does the coach battery supply power to the coach once it's charged? It sure sounds like it simply isn't connected for some reason--a loose or damaged cable, a bad ground connection, the battery disconnect switch set to disconnect (storage) rather than connect (use), a blown main fuse or tripped main breaker, etc.

As best as I can tell, you have a combination of two faults: a bad or mistakenly disconnected converter and something wrong with the battery isolator circuit (such as a bad solenoid). Both the generator and shore power use the converter to charge the battery.
