A vehicle’s electrical system is a system that provides power and control to the various electrical components of a vehicle. It includes:
Power supply:
* Battery: Stores electrical energy to run the engine and power electrical components.
* Alternator: Charges the battery and provides power to electrical components when the engine is running.
Wiring:
* Wires and cables: Connect electrical components and transmit current.
* Fuses and relays: Protect the electrical system from overloads and short circuits.
Control:
* Ignition switch: Turns the electrical system on and off.
* Electronic Control Unit (ECU): Controls various electrical systems such as fuel injection, ignition and transmission.
* Sensors and switches: Provide the ECU with information about the vehicle’s condition, such as engine speed, coolant temperature, and gas pedal position.
Lighting:
* Headlights: Provide illumination of the road ahead.
* Tail lights: Inform other drivers of the vehicle’s presence and intentions.
