<p>An anti-theft device (10) mountable on, in or otherwise adjacent the battery (12) of a motor vehicle includes an enclosed power switch (64) for opening the starting circuit between the battery (12) and starter motor (54) when the anti-theft device (10) is activated, whereby it is impossible to start the vehicle. A normally closed bimetal switch device (78) is connected in parallel with the power switch (64) in one embodiment and is connected to the vehicle battery (12) through the ignition switch (58) whereby, when the power switch (64) is open, an effort to start the vehicle through the ignition switch (58) or by shortening the latter results in a noise which simulates a weak battery. A resistance (134) is also connected across the power switch (64) in parallel therewith to preclude the dropout of pre-set electrical accessories in the vehicle when the power switch (64) is open. The anti-theft device is preferably operably by a remotely controlled encoder (82) having a code signal identified by circuitry (80) controlling operation of the power switch. <IMAGE></p> |
