On another note ,,, My other Friend’s recent rebuild ,,, In basically rewiring his entire van, but keeping most of the wires 120vac & 12vdc at the same length ( I had to splice 3 12vdc lines that grew in length ), we basically pulled the power center out of the original location by “disconnecting the load side” & left the panels wired up.
When complete & re energized, I was getting a “cross feed” on circuits 1 & 2. As “negative is home run ,, but common” it had to be on the positive side. At first I thought his motherboard had gone bad, but started to look at the fuses & with in 1 minute found this;
If you can’t quite figure out the problem, let me direct your attention to circuits 1 thru 6 & specifically 1 & 2. You will see cross contamination of several “strands” of wire touching between 1 & 2 ( pump & fridge ).
So I turned to my Buddy ( because I installed these wires originally & they were perfect ), & I asked him, “Who did you have working on your van up in the Yukon?” Just the RV Tech Shop that redid some plumbing & winterized it”, he said.
I was livid 👿👿. Then I handed him my surgical instruments I use to install virgin factory twist wire into such connections & fully in ,,, not 1/2 way out. I asked him what the labour rate was & @ north of $100/hr I expect way way better than that. Plus ,,, all he had to do to kill the circuit is pull the fuse ( or turn the big red switch off ) ,,, I have no idea why that RV Tech pulled the positive wires out ,,, but that quality of work is tragically crappy. Hey @83Grumman
that Tech is a “Professional” 😳.
In reference ,,, this is how an Amateur ,,, “me” performed the original;
Regardless of all this @Motor7
,,, I prefer this style 12vdc board / panel over the “pigtails” & crimps.
