Future electrical plan
Here is what I plan in the near on the electrical. I will add 2 group 27 batteries under the chassis (in the new Hein tray). That will give about 285Ahr....should be plenty in super cold temps for up to a week. I'll also add a couple solar panels to run a refrigerator full time and keep the batteries topped off. In addition, there will be one more fuse box in the driver side mid ship, so I can easily add more stuff as plans evolve.
The idea of the switch is that I can isolate all the loads, connect to the MB battery, connect to the other 2 house batteries, or just have it all hooked together (which will probably be most of the time). For jumping I could just separate the MB house from the other 2 house batteries and connect 1 small positive jumper cable under the hood, since the starting and MB house are the same type of battery.
Please offer suggestions.
- Missing a few fuses on the batteries?
- Add battery monitor?
- Should just ground my house batteries to chassis somewhere or run wires all the way to connect to the MB auxiliary battery as shown?
- Lighting - I plan to replace the factor headliner light bulbs with LEDs. Should that circuit be put on the house batteries or is current draw so low that it is unimportant? I ran my wires to those locations in case I decide to move the circuit to the house side. Ideally, one might have the switch take power from the house circuit on the always on switched mode, and then still have the switched lighting working when the doors open. I do wonder if I can make that happen by placing a connector that jumpers in the House power on one of those circuits between the 1st switched overhead light and the MB wiring ......worried that it might mess with the MB electrical magic if I get too cute here though.
