Battery relocation. How many fused?
You really should put a fuse on that line. You'll have to go to a stereo shop to find a big fuse and a fuse holder that can handle the load though. Place it as close to the battery as possible.

explain to me how that would work with the fuse on the negative side. Conventional theory is that positve flow to negative. Actual flow is the opposite, negative to positive. I just don't that fuse on the negative side protecting anything. If the negative cable touches metal, it won't do anything. You want the positive cable to be protected from and chassis ground so you would need the fuse on the positive cable. I have never seen a fuse on any ground circuit in 5 years of wiring race cars.
I dont think the fuse cares which way the current is going.if you draw more than the fuse is rated it will blow and stop the flow of current. if you pull your negative cable off of the battery, your car wont start.

If you have the fuse on the negative side only, then yes it will blow if the positive cable grounds out. But after it blows, if the car is running, the alternator is still grounded, and will start welding whichever spot is grounding on the positive cable. Think of it this way, if you start your car and then disconnect the battery ground, it will still be running, right?
So either put a fuse on the negative cable, as well as one going to the alternator, or, put one fuse connecting the + terminal of the battery to both the line going to the kill switch as well as the line going to the alternator, so as to make a Y.
