Could be blown fuse (inline on positive battery lead). Could be bad battery. Could be battery disconnect switch. Could be bad battery and converter. Could be bad converter.
If the battery has an internal short, it will not hold a charge (no matter how long you charge it). In some cases it will act like a very large resistor, and draw more power (trying to charge) than what your converter is capable of putting out. Thus, when plugged into shore power, all the 12 volt from your converter is going to the battery, and your lights may be dim, or not working at all.
Check for battery disconnect switch (may be turned off), check for blown fuse (near the battery), and take the battery to be load tested.
I would suspect the battery (first), battery disconnect (second), fuse (third), and converter (last).
