Pics on battery cutoff switch

You need to read the NHRA rules, which I'm not up on. For some reason you can download them from Bremerton:

I wish you had asked before buying, it's a LOT easier to configure them using a 2 pole (4 terminal) switch, like this:

You MUST have the switch (the large studs) in the POSITIVE cable. But you must configure it so that it not ONLY kills the battery, but ALSO kills the engine. The engine will continue to run on the alternator, whether it's a conventional (external regulator) or a "one wire" setup So you must devise a way to kill the alternator and so kill the engine.

There are also special provisions in the rules as to mounting the battery. If you don't have a metal firewall behind the seat, the battery must be in a sealed box VENTED TO THE OUTSIDE of the car. I don't remember, it might be that the box must be metal.

"crackedback" is probably the expert on trunk mount batteries around here.
