Received guidance from a logical soul on the Kawie Riders forum: Acc Fuse Block Power to BAT LOAD, install new cable from BAT LINE to AUX + (and) leave the other two (Battery Charger + and Bat + to Isolator connected to the AUX + terminal since neither are loads.

QUESTION: How to wire the C/B into this current dual battery set up. EXISTING SITUATION: MAIN Battery is OEM and feeds OEM circuits. Added an AUX Battery in the OEM dual battery location. Connected the AUX - terminal to the MAIN - terminal. Connected the 100A Accessory Fuse Block power cable to the AUX + terminal. Installed a smart isolator between AUX and MAIN batteries where a cable from AUX + goes to the isolator and a cable from isolator to MAIN battery + terminal. Installed separate QD battery tender cables to both AUX and MAIN batteries + and -. The dual battery system appears to work as intended. For this Phase 1 improvement, to avoid having to constantly pull the leads on the AUX + battery post off and put on, for testing or maintenance of Accessory circuits, I wanted a more convenient and safer way to open the circuit from the AUX battery + terminal the Accessory Fuse Block. I called an off road dealership and was told to install a much larger capacity circuit breaker than the 100A rated Fuse Block and was recommended to get a 250A C/B like the one in the pic, which I did. I was told the reason for the C/B high amp rating was two-fold (a) to trip in the event of a battery short circuit and (b) to be able to conveniently open the C/B to kill power to the Accessory Fuse Block without removing leads from the AUX + terminal. The 250A C/B has two posts labelled "BAT LOAD" and "BAT LINE". There are currently three connections to the AUX + post: (1) Accessory Fuse Block power cable, (2) cable to Isolator AUX in terminal, (3) cable from AUX battery charger.

Am starting a major transformation of a ndw Mule Pro FXT to turn it into a Reliable Scouting & Hunting Vehicle. Interested in first finding the absolute best off road forum that has great participation the more technical areas like planning accessory wiring, ground clearance options and bracket lifts. Someplace where people who know how to do stuff, participate. Is this a good forum for more technical stuff and where there are Mule owners who upgrade and work on their machines? My project is taking a new Mule Pro FXT and taking it through a complete project from adding lots of electrical, adding a fuse block, ground block, OEM heater, dual battery system, gun rack, sound system, nav display, inverter power outlets, 360 degree LEDs, cabin lights, W/S, phase 2 upgraded tires, full cab, rear W/S, and so on.
