hcbph that sounds like a good idea when you say new cables did you buy two new negative battery cables to run from the block to the switch and then to the battery and where did you mount the switch and was the switch installed in a typical metal electrical box? any info or parts numbers ect. on how I can set this up would be appreciated and thanks for the info
also you speak of a 250 amp IIRC Switch 250 amps sounds pretty large for a car then again I don't know lol should that be 250 volts at 16amp switch maybe? sorry i'm no mechanic here just trying to figure out what this means and what does IIRC stand for can you recommend a switch and cable to use for this maybe a website and or part or model number? thanks again
The one picture shows what I tried (like some questioned) for a year or so. One day while driving, it snapped off between battery and the screw to cut off current in the middle of the highway.
I then started asking questions and including Summit, came to the conclusion a 250 amp cutoff would be more than sufficient for my needs. There's an area right below the drivers headlight that already had two 10mm IIRC bungs in the frame and an open space. I made the black plate to fit in the area and bolt to the frame. I then took some Styrofoam and taped it to the plate and worked the headlights to insure they wouldn't catch on the switch, once that was confirmed I drilled the plate to accept the L bracket to mount the switch to. The cable between the block and the switch IIRC is a 2 gauge and has eyelets on both ends. The one between the switch and the battery IIRC is a 4 gauge as that was all I could find in the length I needed. I unhooked the existing negative cable and taped it up under the hood but left it on just-in-case. New cable goes from the block to the switch plus I added another ground strap from the frame to that lug. Other cable goes from the other lug to the battery. Turn the handle 1/4 turn and it engages or disengages the switch.
The cables I got the one made up by a shop that does them for boats IIRC and other one with the end on it for the battery I found online. I had to look for them and eventually found what I wanted.
I've had zero issues with this setup. If I ever do in a pinch all I have to do is unhook the new cable from the battery and hook the original one back on. Like I said, I did some checking before buying the parts and the 250 amp cutoff switch based on the info I got back was sufficient for my needs and so far it has worked without any issues.
