I run a GM one wire alternator. My kill switch is on the non-ground side
of the battery (positive), and I have the alternator run through the
alternator posts of the kill switch. I never shut the car off with the
kill switch and have never had a tech inspector ask me to do so. But, it
will certainly kill everything. It also makes sure that there's nothing
hot in front of the kill switch when it's turned off - good for when
working on wiring and stuff near exposed terminals. It's a very simple way
to wire the thing up, and I don't have anything that bleeds charge off of
the battery when the switch is turned off. The tech inspectors DO ask me
to kill the brake lights with the kill switch.
