David here with my 2003 13' Patriot Deluxe "Bandit." I'd like to begin by saying I am no electrician. I dabble with little things at home (replacing outlets, dimmers, etc) but get a bit lost once we start entering the equations of Watts vs Amp vs Volts...
So here's my situation. I recently decided to move my battery from inside the trailer to the front tongue. I have welded a tray for a battery system that I put in parallel (2 12v group 27's, and now doubled the amp hours.) I have run the main 8AWG Pos and Neg lines from the tongue along the frame and into a Sea Blue Fused power Bus. From the power bus I have run separate 8AWG pos and neg lines for three separate components. One goes directly into the casita house power. I just removed the old pos and neg wires and screwed in the new lines. The second set of 8AWG pos and neg lines run from the power bus into a solar charger. And lastly, the third set of 8AWG pos and neg line run into a stand alone 3/8s and 5/16 power bus. I am using the negative side of this power bus to attach a shunt, that had previously been on the neg side of the battery. All of these lines are fused with 30amp ATC fuses.
So when I finished wiring everything up, I turned the battery disconnect switch to the on position. The solar charge turned on immediately and seems to be fully functional. (at least I know power is coming through that Blue Sea Power bus.) However nothing in the Casita is working. (no lights, no water pump, etc) So I back tracked through what I had disconnected and notice a green ground wire that was attached to the old negative (white) casita wire. Does it make sense that nothing would work without me having reattached that green ground? My plan is to get the same gauge wire, crimp/connect it to that green ground, and extend it to where my new shunt is. I will attach it just as it was before...does that sound correct? Additionally, the negative wire coming from the water pump had been connected to that shunt. Can I do the same with the wire and extend it to the same shunt it had previously been attached to? Am I missing anything? Also, the wires are so buried in there I am concerned that I may be missing another place where Casita branched off either the original pos or neg lines. I caught that one green grounded line, but does anyone know if there are any other connects on those original lines?
thank you in advance for anyone that understands this electrical system!!
