DC ground, which I originally expected to be near the converter or right beside the battery on the tongue.
Every source I've found says that each DC circuit should be grounded individually to the ground block (somewhere on the frame).?
As one example of what I'm trying to ... resolve (don't know if it's wrong, but have been told by several electrician types that it is) ... the 12V aux socket pos lead is 10AWG, but the neg lead is just 14 AWG, and ends in this multiple daisy-chained set of wires going somewhere toward the tongue. I haven't been able to trace it fully yet. As dad used to say, gozintas need to equal gozoutas, so I was aiming to replace that 14AWG with 10AWG. Then I discovered all the quick-splicing and now I don't know where to start fixing what.
I do understand the basic idea that if I have up to 15A draw to that socket (this from the reefer mfr), it requires a neg lead of the same capacity to complete the circuit. I had expected the neg lead to run back to the converter (since that is grounded). Instead, there's this white 14AWG wire running into that mess of quick spliced white wires of the same size and thence forward toward the tongue.
Oh. And there's a "spare wire" (black) with a butt connector, but no matching end anywhere in the vicinity. I know it can't be related to the 12V aux socket I'd worked on because the connectors are different.
Aliner has told me unequivocally that they can't supply me with a factory wiring diagram :/
