Kill switch wiring

[Greg Amy]

Any idea what amperage I should use?

Depends on your wire size...most cars are around 12AWG, I'm guessing? that would be a 20A fusible link. Of course, if the power wire is shorted to ground, a battery can probably put out 500A before exploding...I suggest it would be best to size the fuse for the wire you're using.

There's only about a 10 or 12AWG wire going to the ignition stuff, but from the battery to the kill switch/starter, it's a 4awg wire. big stuff. That's the one that concerns me since it'll easily suck up all of the current the battery can put out until it explodes. (don't ask how I know....)
