There is also one near the metal box the long cord goes into. (as pictured).
There is another one near the battery itself.
Either one tripped can cause your problem.
The one near the metal box is in the circuit to protect the camper from a short in the umbilical (like severing it in a turn). The one near the battery is to protect the camper from a dead short at the battery with the AC power driving the converter.
If the battery alone will run your landing gear or main slides but nothing else, the problem is at the umbilical. If the battery alone will run nothing, it is the one near the battery.
The red wire in this photo that goes off the plywood to the right goes to the next current limiter at the umbilical (5th wheel is up under the pin box); then to the converter.
