If there is 0VDC at the battery cables with the batteries disconnected, but there is 13.4VDC at the converter output, check two things.
First, check the battery cutoff switch. It may be in the "batteries off" position (red key can be removed from the switch). If there is voltage at the switch input but not at the switch output, possible faulty switch.
Second, check the DC mini-breakers located in the front compartment and/or adjacent to the batteries. There are two, three or maybe even 4 in a row. Those mini-breakers have a long history of looking great (plastic case) with significant corrosion, pitting or arcing of the internal contacts. They come in various amp ratings and should be replaced with the same amperage. If they are in a metal can, the amperage is stamped into the case. If they are plastic, it's printed on the bottom of the case.
If all that is good, but still no voltage at the batteries, but you DO have output at the converter, it's a loose connection in the wiring "somewhere in the belly".... Let's hope it's a bad breaker or a bad BCO switch.....
