Thread: battery cut-off on 03 cobra!!!!!

    battery cut-off on 03 cobra!!!!!

    So NHRA says the cut off must shut off the car when the switch is off. How do you do this? I tried to just run off the + side but when the car is running the car will not shut off, if you turn the switch off. Help!

    Your switch also has to interupt the battery "excite" terminal on the alternator.

    yea, Just get some 8 gage power wire and run it from the alternator to the battery in the rear and eliminate the stock wire.

    Yeah, in theory, but in reality you risk spiking the PCM if you do this. You carburtraitinon guys had it sooooo easy back in the day!
