  • Electrical System Upgrade

    I have begun my electrical system upgrade.
    so far i have removed the old alarm system, and all of the half ass installed electrical circuits i have ever added to the system.

    in the past i have used those things that you plug into your fuse box to add a new circuit. they were ok for the time, however i wound up with 4 of them.
    in order to keep the electrical system sound, and minimize chances for failure i am adding some boat circuitry.



    this is the auxiliary fuse box that will protect everything that didnt come with the jeep from the factory.
    things like the cb, air compressor, lighting, etc...

    i do have a dual battery system in my jeep, which was being isolated with a cole hersey isolator. those types of isolators have a high resistance, and a lot of voltage drop.



    click the picture to see the charging solenoid info. this is a really trick piece of electrical.
    it charges one battery at a time, going back and forth between them. when severe loads are being put on the system, like durring winching, it will isolate, and protect the secondary battery.

    it can be switched from inside the cab to put the batteries in paralell, or manually protect the primary battery, or do its own thing charging both batteries.

    rather than having so many wires going directly to the battery, i will install this "bus" to distribute the high amp cables to their designated areas.



    for example, there will be a cable from the battery to the bus to energize it, then the auxiliary fuse box, winch, etc.. will be connected here so there is little to no resistance.

    all other items like the cb, viair back-up compressor, etc.. will all be home runs to the new auxiliary fuse box. trouble shooting will be easy, and less likely to be needed.

    i'll get some pictures of the parts,a nd progress.

    Nice! So are you dumping the current fuse box?

      i didnt finish my initial post..

      no, i will be isolating all of the "extras" from what the jeep came with from the factory. if something catastrophic happens, i can just disconnect everything that isnt needed to make the jeep function.

      this is something i have been wanting to do, and the mobi-arc burning up from the winching load just pushed it to the front of the list.

          my alternator is 165 amp. it is a big mova.
          when i get this finishad it will be one mean electrical system.
          i think i will be hard wiring in the inverter as well with one 110v. receptical for charging the camera batteries, and grinder if needed.

          i havent decided on a location for the inverter yet. still up in the air on this one.

                Sounds awesome. As far as the isolator, I would personally go with something completely solid state (no moving parts) such as hellroaring but that relay looks pretty cool. It can candle more current but the hellroaring is good for 200 amps continuous, 300 for 15 secs, and 500 max so it's probably more than enough.

                In any case, the setup sounds sweet! What kind of batteries do you have? I'd make the main one a deep cycle for sure.

                  Cool set up. Will you put a fusible link between your new fuse box and the power cable to it?

                    here are some progress pictures of the wiring.
                    everything is coming together.

                            Hey Erik.

                            Any pics of this completed project? I'm pretty curious. Wiring has always completely baffled me, and left me with blackened fingers in the end. Then I have to call dad to see what I'm doing wrong.

                            He normally tells me, "...disconnect the battery before you start working on it."

                              Is this the first Erik project that did *not* involve welding?
