Need help with 1973 Dodge Sportsman coach electrical issues

Hi all, I'm helping to restore a 1973 Dodge Sportsman (B300) RV and have run into some issues with the coach electrical system--hopefully someone out there can help. I recently replaced the battery...

you have power/voltage at the fuse panel

ALL 12vdc circuits are TWO (2) wire positive and negative

since almost everything is dead

i would start at the MASTER Negative/"Frame-Ground" connection located at or behind the 12v converter box, something is broken-disconnected or corroded to the point that there is NO circuit continuity between there and the batteries/converter charger

also check the MAIN ground/Negative cable from batteries to frame and from converter to frame and-or batteries
