In all the conversation, I have yet to see the answer about what breaker tripped. Was it a 120 v breaker? or a 12 volt DC breaker, like what would be at the battery feeding the main 12 volt circuit to the rig's electric panel? If there is a 12 volt auto reset breaker at the battery, it is very possible that if that failed completely, you would have no 12 volts to your panel and your converter could not charge your battery. Make sure we are talking apples and oranges here. Most of the time, breakers are 120 volts AC, like what comes from the pedestal through the shore cable. Except for the 12 volt auto reset breakers, all 12 volt DC is usually protected by fuses. Also, do you have a battery disconnect switch on this rig? And, if so, is it turned on? The ones installed on these rigs, when the circuit is connected, the red plastic key can not be removed, and if the circuit is disconnected, the key can be removed. If the disconnect switch has the circuit open, your battery will not be connected to the converter and the battery will become discharged, no 12 volts.
