Just for clarification, does your Kill Switch operate as a battery kill switch or does it also kill the motor while its running (thus killing the alternator too)? It seems that most of the kill switches I've seen are single pole switches and I don't think you'd want to run both your starter and alternator through the same switch. Am I missing something here or is a battery kill switch sufficient for SM rules?

Thanks,
Paul

It is required to isolate the battery and kill the motor.

The switch must stop the engine as well as all electrical circuits i.e. brake lights.

This is probably the most frequent item I have found, while doing annual inspections, for the last season. Like the other Wheeler said, above, it must shut off everything. If your engine keeps running, when the switch is off, you won't pass tech.

Hey Paul,

Just buy the kit offered by Davew at Advanced Autosports. Easy to use and you won't have poor conections as I had on my first car.

You guys are the best! Which wire is it that gets interrupted to kill the motor while it is running?

Paul, just do what George stated above. Excellent kit, everything you need, and clear instructions.

The power to the Igniter in my car.

And if the switch ever fails (or gets turned off) the car will not run. Been there.

I would have just bought his kit but I'm already so far into this project that many of his parts wouldn't be needed at this point. So all I need to do to finish the job is to figure out which wire to interrupt for the ignition.

Wouldn't it be one of the wires that goes to the keyed ignition. Does anyone have that info?

Thanks,
Paul

On a 1.6 it cuts the power to the igniter which comes from the key switch.

The kit being refered to is only the switch and wiring and not the Spec Miata in a box kit if that is what is confusing you. Check the Advanced Autosport web site.

Thanks Terry. No confusion here about which kit Dave is offering. I already have almost everything in that kit except for the metal bracket to hold the switch. I'm mounting it in the air vent on the drivers door side of the steering wheel.

I've bought other stuff from Dave and everything is first rate. I just had a lot of this stuff around the shop already and it didn't make sense to buy it again.

Make sure you have the b-terminal to the alt insulated. My little rubber cover fell apart and that terminal is still hot so if you short it with a wrench (to the intake manifold support bracket for example), smoke comes out of the trunk and you have to replace the 10G wire since it burned up the insulation.

[yep]

I just got my "new to me" Spec Miata about a month ago.

As I've been going through it, I noticed that the kill switch is basically just a battery kill. (Car won't start unless it's on.)

I too have been trying to get clarification on this via the almighty Internet.. and it's crazy!!!!

People who all seem to know more than me give conflicting advice. My switch does not kill the car once started. Yet it's got several SCCA tech stickers in it?

Nick, when they DO test the kill switch they will refuse to let you race. In the SowDiv, it's a favorite thing for tech to check and they check it every time they give it an annual.

Do I turn my 99 Hard S into a killerfast SM or seek a donor?

Thanks. I took a look. It's a two pole, battery only...for sure. Going to have it changed. No official SCCA techs for me real soon anyway! Since May, I've done two DE's in my daily driver. Did an open track with the SM. Doing at least one more. Then another DE, then hopefully my club license. By then it'll be September.

So I'm a little of the newbie that's been bitten. But don't hold it against me! The car was well south of 10k, and I've already done my own homemade rattle can clean up of the "straightened" fenders. [thumbsup]

Nick, you still want to get it working properly. I work PCA DE's and if I see a car with a kill switch I will use it depending on the situation and expect it to work as advertised.

You don't need more than a 2 pole to do Dave's kill switch method.
