Automotive circuits generally consist of power supply circuits, starting circuits, ignition circuits, lighting and signal device circuits, instrument information system circuits, etc. Power supply circuit: Also known as the charging circuit, it is composed of the battery, generator, regulator, and charging indicator device. Power distribution and circuit protection devices can also be included in this circuit. Starting circuit: This circuit consists of the starter, starting relay, starting switch, and starting protection circuit. Devices for preheating during cold starts and their control circuits can also be included in this circuit. Ignition circuit: This is a circuit unique to gasoline engine vehicles. It consists of the ignition coil, distributor, electronic ignition controller, spark plugs, and ignition switch. Electronically controlled ignition systems managed by microcomputers are generally categorized under the engine electronic control system. Lighting and signal device circuit: This circuit includes headlights, fog lights, marker lights, turn signals, brake lights, reverse lights, interior lights, and related control relays and switches. Instrument information system circuit: This circuit consists of instruments and their sensors, various warning indicators, and controllers.
