    The comprehensive diagram shows most of the electrical mods incorporated into my '17 F-350 and '19 315RLTS. The diagram is for me (not a "professional" schematic), but I thought someone might find it interesting or even useful.

    The attached PDF is a compressed, "small", version but after downloading and opening in Adobe Reader (or similar program) you can zoom in to see detail. I have a much larger version I can share over Dropbox should anyone want a copy.

      If the engineer has any "what was he thinking!" reactions I'd very much appreciate reading them.

          Diagram and PDF in post #1 updated to reflect changes in OEM 12v wiring. Links to threads updated, too.

              I used Photoshop for the comprehensive diagram.

                Due to many inquiries I added an overall presentation document to post #1. The PDF (from a PowerPoint presentation) gives an overview of the entire project. I hope individuals (like Famtraveler24 ) find it helpful.

                  Outstanding work. I have a 2020 315 and would like to set it up like yours. Everything is well explained but I need to know how you ran the 6/3 cable from the front to the power station?

                      Thanks Howard. Unfortunately the link to Electrical Project Presentation v7 reduced size.pdf in your original post is broken.

                        Odd--the "attached" files (at the bottom of the post) work. I've updated the thread to point the reader to that location.

                        Thanks for the heads-up, Mark!

                          FTC,
                          When you get a chance check out the Welcome Letter to New Members: https://gdrvowners.com/forum/main-fo...to-new-members

                          For the wiring question, the 6/3 runs by the furnace (in the hutch) down through the floor in the existing opening created by GD for their wiring. With the coroplast opened (just the street side from the wheels forward) I snaked the new wire forward, following the same route as the OEM wiring.

                          Note that this is not easy--the solid ("household") 6/3 is a royal pain to work with in this tight environment.

                          Once I got to where the plumbing goes up into the pass-thru (at the Nautilus Panel) I had the wire follow the same route. From there it goes through the box I built for the batteries (the wire above the batteries) over to the inverter that is mounted on the curb side of the pass-thru.

                          The internet connection at the campground is very weak or I'd post pics. If the description above isn't clear fire back.

                          Again--welcome!

                          Howard

                          P.S. Recent post about battery temps is related to the electrical info and has pics that may help. https://gdrvowners.com/forum/operati...-battery-temps

                            Updated the Master Diagram in post #1 to show the manual switch (removed Smart Phase Selector), reconfiguration of circuit breakers in Power Distribution Panel, and the incorporation of hard-wired Mopeka sensors. The attached PDF in post 1 is 2MB and with Adobe Reader anyone can zoom in on the details. (The jpg will be fuzzy if you try the same thing.)

                            Questions? Fire away.
