Battery Disconnect Switch - Event Date: 16 Dec 2017

Disconnect from shore power and remove a battery lead from the battery(ies). Your choice, they both work to kill the circuit. I like "+".

Open the door of the power center. Remove the 2 screws that keep the front in place. Lift and remove front. On the right side/half is all the 12v circuits. Note the large 6/8 gauge wire coming from behind and going to the "+ Batt" terminal of the fuse panel. (it's the one attaching at the bottom of the panel) Do not confuse it with the wire coming from the converter.

Now, remove the 6-8 screws holding the entire power distribution box in place. Pull it forward/out. Disconnect battery feed wire. Figure out how much run you have in the wire coming from the battery. Drill a hole and mount the switch where you want it within that range, or add to the length if needed. Run a new piece of wire from the other side of the switch back to the "+ Batt" connection on the distribution board. Verify switch operation. Reinstall box and cover.

Enjoy celebratory beverage.

Interesting. Following the main 12V cable is not difficult, but I think most of us chose installing near the battery because it is easier. I started a firestorm on another forum on whether to place in the positive or negative side, so I won't rehash that. I take it you want it inside like some motor homes. It needs to go into a battery cable line, not any 12V wire, so you're choices are limited. Simply follow those cables into the power distribution. Good luck.
