You will still need a battery for the breakaway circuit. We need to track down the "open" between the converter and the battery.
There are two current limiters between the converter and the battery. One AT the battery and one at the metal umbilical junction box.
Pres on the short side and feel for a "button" and see if it can be pressed in; also examine the current limiter for corrosion and damage.
Here are some photos of what to look for.
