Vehicle electrical system
The vehicle’s electrical system is responsible for supplying electrical power to the vehicle’s components and systems. This is a vital part of the vehicle that allows you to:
* Start the engine
* Power headlights and other external lighting fixtures
* Control internal electronics such as audio systems and air conditioning
* Power safety systems such as airbags and ABS
Main electrical system components
* Battery: Stores electrical energy to start the engine and power systems when the engine is off.
* Alternator: Converts mechanical energy from the engine into electrical energy to charge the battery.
* Relays and fuses: Protect the electrical system from overloads and short circuits.
* Wire Harnesses: Connects various components of the electrical system.
* Computer: Controls and monitors the electrical system to ensure optimal performance.
Basic operating principles
When the engine is running, the generator produces electricity, which goes to the battery. The battery stores this energy and provides it when the engine is not running. Electricity from the battery passes through fuses and relays before being distributed to various vehicle components.

Troubleshooting
If there is a problem with the electrical system, the following symptoms may appear:
* Difficulty starting the engine
* Dim or flickering headlights
* Malfunctions in the internal electronics
*Battery leak
Troubleshooting these problems requires specific knowledge and tools, including:
* Multimeter
* Wiring diagram
* Wrenches and screwdrivers
*In some cases, it may be necessary to contact a professional mechanic.
Service
To keep your electrical system in good condition, regular maintenance is necessary, which includes:
* Checking the battery and generator
* Cleaning battery terminals
* Checking wiring harnesses for damage
* Checking relays and fuses
Regular electrical system maintenance will help prevent costly breakdowns and keep your vehicle running safely and reliably.
