The battery may be suspect. This is a typical senerial of a battery having a shorted cell probably due to battery fluids being boiled off by a single stage 13.6VDC converter.
When the cells short out in the battery this puts a hugh load on the converter. This should blow some fuses in-line between the converter and the battery terminals. Sometimes it just makes the converter fail.
I would check the battery fluids, and find all of the fuses between the converter and the battery terminals. There should be a in-line fuse real close to the battery and two additional fuses back on the 12VDC Distribution panel labeled REVERSE POLARITY. Any one of these fuses will keep the converter from charging your battery. Only a couple of thing can cause these fuses to blow one being having the battery terminals wired up wrong or sorted cells in the batteries.
A fully charged battery should read 12.6-7VDC at the battery terminals with the converter not connected to shore power. When you turn ON the converter these same DC VOLTAGE readings should jump up to 13.6VDC telling you the converter and all the inline fuses are working normal.
