If there is an internal battery short the converter will not come online.
That is why you should remove the negative cable from the battery terminal to eliminate that as the problem.
THEN check for 13+ volts at the two battery posts on the DC distribution board (or four idiot lights on the MicroMonitor panel when you press "Battery").
"Battery" is really NOT your battery; it is the DC voltage on the camper. It will work even if the battery is removed as long as the converter works. It only reads "battery" voltage when you are not plugged into shore power or a generator.
In the below figure you will see a Vcc+ post (this is a WFCO diagram) but you should have something similar. You should check for 13+ volts between there and "NEG"
Vcc is where the positive from the converter connects to the fuse board. The Battery POS is where the battery lead goes. There should be reverse connection fuses between Vcc and the battery post.
