Fun times, especially since most of them used 48V batteries and our radios were 12V.
I have seen that so many times, it makes your head spin. Some installers / technicians take pride in their work and do it neatly. Others, not so much. Then there's the type who only have half a clue and double up on circuits, neglect to ground a circuit and their work is shoddy all the way through.
Like mainah suggested, you need to separate what works off battery and what works of 120VAC (plugin). Break things down into smaller components and see what is VAC and what's VDC. There are a lot of people that know various models and the details of each. EG: Fridges are typical two way and sometimes 3 way AC-DC or AC-DC-Propane. Tell us what you have and the gang here will help out
