<p>The invention activates and deactivates components in a vehicle using an engine in which the ignition switch is left in the "on" position even when the engine is shut down. An engine running sensor (10) is provided for activating and deactivating components (78, 80) of a vehicle in response to the vehicle being in a running condition. The sensor (10) includes an electrical signal generator (24, 26, 36) responsive to vibrations of the vehicle, a switch (70) responsive to the generator (24, 26, 36), and the components (78, 80) being activated in response to the switch (70). The generator (24, 26, 36) is mounted on a portion of the vehicle, preferably proximate the engine, to vibrate as the engine runs. The generator (24, 26, 36) need not be exposed to any of the pressurized systems of the vehicle. The described embodiment is useful for ensuring deactivation of the hourmeter (80) and electrical monitoring system (78) of a vehicle when the engine is shut down.</p> |
