Device for recording start sequences of car, has command and control unit including input connected to common point between control coil of relay and bypass switch, and another input connected to motor rotation detection sensor

摘要

The device has a relay (7) for powering a starter (11) that drives a motor (12) of a motor vehicle i.e. car. A command and control unit (6) includes a first input (A) connected to a free terminal (444) of a bypass switch (5), and a second input (B) connected to a common point (103) between the output of an ignition switch (1) operated by an ignition key and the bypass switch. A third input (C) is connected to a common point (188) between a control coil (88) of the relay and the bypass switch, and a fourth input (D) is connected to a sensor (13) that detects rotation of the motor of the car.
