Sometimes this happens when you accidentally hook up your battery in REVERSE POLARITY... While you are checking go find the word "NEG" of find the symbol "-" on the battery case and make sure this goes directly to FRAME GROUND on your 12VDC battery hookup.
If this is in REVERSE ORDER than two fuses in your Power Distribution Panel labeled REVERSE POLARITY will be blown as well as an IN-LINE FUSE that will be located very close to the POSITIVE battery terminal.
Be sure to correct any reverse polarity connections first before replacing any blown fuse as they will just blow again...
I always just check my battery terminals with a digital voltmeter and it should read around 12.6-7VDC if charged. Then I go plug in the trailer shore power cable and then measure the battery terminal again. It now should be reading 13.6VDC if the on-board converter/charger is working and all of the connections between the converter/charger and the battery terminals are in good order.
