  • Patent number: 5729192
    Abstract: An automobile is remotely disabled by shunting a portion of the ignition circuit. The remote automobile disabler device receives a remotely transmitted disable signal and, in one embodiment, forms a low resistance connection with the negative terminal of the battery so as to create a break in a low current capacity portion of the ignition circuit. The low current capacity portion may include a circuit breaker. In an alternative embodiment, the battery is redirected through a shunt circuit which includes a resistor. A voltage drop is thus formed which reduces the operating voltage to electronic components in the ignition circuit below the threshold voltage and disables the automobile.
