How do i bypass teh isolator?

[moto552]

I have a 2016 Tacoma that I already have installed a Aux batter that is isolated and used to run a ARB fridge when i used a pop up tent to camp.

I wired my new to me swift to my Aux batter and now i want to eliminate the isolator in the camper so that the fridge will run longer on both of the batteries.

I looked through a bunch of the battery forums and did not see any questions like this.

Thank you in advance.

On the isolator itself, unscrew the heavy gauge wire from one terminal and move it over to the other terminal so both heavy gauge wires go to the same terminal post. The isolator is then just a junction block. You can disconnect the ground wire (the thin wire going to the isolator) as well so the relay won't activate.
