Hi Mike,
Yes, disconnect the positive. The Pegasus switch - yes as well. I run an alt=
ernator and was shocked (pun intended) to hit my kill switch with ignition r=
unning and find car still ran. Proper kill switch fixed it wiring was clear i=
n instructions.=20
Good luck,
Ron Soave

<div>I have been doing a lot of reading on kill switches. My
mechanic/tutor (who is never, ever, ever, wrong) insists that they should
be on the ground wire, which is how they are done on race cars. This may
be OK if there is no alternator, but will not kill a running engine with
alternator. It just runs on, finding a ground for the alternator output
somewhere else. More important, disconnecting the battery ground on
a running engine can cause a voltage spike that apparently can fry
the alternator. A properly-wired kill switch is on the positive terminal
and has a 3 ohm/11 watt resistor to ground to prevent this.
Pegasus Racing has detailed instructions. I may already have damaged mine
before I learned the proper way to wire it. Time will tell.</div>

<div>This brings up another question: People put the green-knob battery
switch on the negative terminal. This not only has the same run-on, fried
alternator problem, but also leaves the entire positive system of the car
hot. Since there are grounds all over the car body, I think that
means we can get arching to the body pretty much anywhere. If the
positive terminal is disconnected, there is no power anywhere, as nothing will
come out of the ground side, regardless.</div>

<div>What say you all?</div>

<div>BTW, after two years of struggling to start the new engine put
