Another posibility is your converter main fuses.
Many converters (Alas not mine) are incorporated into the power distribution panel, When this is the case normally both 12 volt fuses and 120 volt breakers are beind the same door (If that door is inside a cabinet I'm talking about the inner door) NOTE that if the converter is behind the fuse panel, the breakers and fuse are normally in the same "Box" but the reverse is not always true.. I have presonally seen fuses and breakers in the same box with a remote converter (Which in that specific case was indeed behind the fuse panel, about a foot behind it, in a compartment but hey, not intergrated into the distribution panel).
In the intergrated units, some of them have a main fuse just for the batteries, a 2nd one for the converter and then the branch fuses are hooked in between those two mains.
Popping the battery fuse, causes what you see. Since the jacks have their own fuse elsewhere.
Home is where I park it!
