Kill Switch - The vehicle will not start unless a hidden switch is activated. The switch prevents electrical current from reaching the coil or carburetor. Check your vehicle warranty before installing a “kill switch.” Vehicle Kill Switches, being custom installed, will stop most amateur thieves and the punk kid on your block from stealing your vehicle better than most standard-installation alarms.When it comes to stopping professional thieves, however, they are able to bypass kill switches in a matter of minutes. 1) A kill switch is useless unless hidden. The thief will try to start your vehicle, wasting time, before he realizes something is wrong. Most amateurs will give up at this point. The disadvantage to this, and why it won't stop a professional thief, is that it is typically hidden in a easy-to-reach place in order to be convenient for the driver of the vehicle. The wiring is often easy to trace & splice back together. 2) The installation is custom. Unlike factory-installed antitheft systems & out-of-the-box car alarms slammed in to your vehicle by an $8 per hour technician, this alone makes it tougher for a thief to beat because he doesn't know right where to go. A weakness of most alarm systems is that in addition to being installed in one of the few standard locations, the wires are color-coded to make it easy for the installer. Obviously this also provides a road map for the thief -- anything that goes in fast, comes out faster. Al meu era sub pielea de la schimbatorul de viteze, se simtea doar la "pipait".Era un switch cu o "tija" (nu stiu cum sa-l numesc altfel), pe care daca il dadeai in dreapta taia curentul, iar in stanga cupla curentul.
