Ground wire is not connected somewhere. all the kill switch does is ground out the electrical system, so if it doesn't work then the ground wire is loose or not making a good connection somewhere. check the wire harness, but the ground is usually black.

got it fixed, after checking all switches and wires, swapped out the cdi, works good now, so box was bad
