Alternator Wiring with Kill Switch

Frankly (I think) the easiest way is with a 4 post (double pole) kill switch. If you look around, there now exists several brands that offer good, heavy duty switches in 4 pole. I'll look later, I thought I had one bookmarked

Anyhow, run two light gauge wires from the small accessory terminals on the kill switch up to the front. Use them to break a relay circuit, with EFI you can break the pump relay, otherwise break the ignition. If you run MSD you don't need a relay.......just wire those to in series with the "small red" switching wire on the MSD

Many guys run a separate no6 or so charging line direct to the battery. In my opinion this violates the rules. They say "kill all power" or words to that effect...... It certainly is not patently "safe." That leaves a pretty big welding lead ?? hooked to the battery, live.
