Default Kill Switch Rule??

I know...I know...I should just get a rule book but, I never got around to it.

Anyway, what's the specific rule for cutoff switches? I don't plan on moving the battery to the rear. However, I've heard some people saying 9.99 and quicker in competition needs one no matter where the battery is.

Thanks,
Andrew

I *thought* it was only needed for cars with relocated batteries, but I don't know for sure. I'll let one of the experts chime in.......

is there any specific way it has to be done? a buddy of mine bought a car with one and it had the battery in the rear. after further inspection, the ground wire is ran through the kill switch. it works like a charm, as its supposed to.

You DO NOT interrupt the ground side of the battery. Positive side, and it also has to kill the alt output...

Any time the battery is relocated to the rear of the car there has to be a kill switch. If you do not have a wall between the driver and the battery it has to be in a metal battery box with the box being a certain thickness (l think 1/16th"). The switch has to be clearly visible and accessable with it cleary showing which was is off. If it's a push/pull type, "OFF" has to be PUSH. Here the legal and correct way to wire it. -Mark

also just for you guys that still drive em on the street flaming river has a kit that uses a removable rod for the cutoff and if you just get an extra taillight housing you can drill the hole in that housing to have it go through there with the switch and all so that you dont have to drill the tail panel or worry about not having a tail light for the street

Kyle is that technicially legal without the battery sitting inside a box? or is it being behind the plastic (which i assume you usually have in place) good enough so they don't bother you?

If there is no divider between the driver and the battery then it has to be in a metal sealed box. If there is a divider between the driver and battery (has to be a certain thickness of metal) then it can be in a open container.

Thanks for that... nice to know. I like running the little pc680 in the stock location, and until someone tells me I have to put a switch on my car I am leaving the little batt up front. After that I guess it's a moroso battery box in the t-top area.
