As suspected, its wired incorrectly. If you fallow the 2 yellow wires from the ACR, they go directly to the battery terminals. They should directly to the switch's 1a and 2a terminal. These 2 posts are are on the boat side of the switch, and isolated from the batteries when the switch is off.
Theres no need to do away with the ACR, just wire it correctly, which will probably take less time to fix, then ditch.
