The Stovebolt Site Forums The Shop Area General Truck Talk Battery beneath floor

I also kept the battery under the truck and added a battery isolator switch. I installed mine on the passenger side seat riser. I disconnect the battery every time I park it. I also wanted it inside as I thought if I had an electrical fire more that likely I’d be in the cab and I could shut it off quickly. I installed it on the negative cable as I didn’t want 12v positive cable passing thru the floor creating a dead short if the grommet failed. If the grommet on the ground wire failed it would only complete the circuit. If the key is off it should have no consequences!
