Electrical equipment is one of the most complex systems in a modern vehicle. The operation of the engine, lighting, comfort, and road safety depend on its reliability. Our team in Finestrat is ready to diagnose, repair, and service your vehicle’s electrical equipment quickly and professionally.

What is Vehicle Electrical Equipment?

Electrical equipment is a collection of systems and components that provide electrical power to all electrical consumers in the vehicle. This includes power generation, storage, distribution, and use of electrical power for various purposes.

Main electrical equipment components:

• Battery — stores electrical energy
• Alternator — generates electrical power during engine operation
• Starter — starts the engine
• Wiring and cables — transmit electrical power
• Fuses and relays — protect circuits and switch
• Sensors — monitor various parameters
• Lights and bulbs — lighting and signaling
• Electric motors — drive mechanisms (wipers, window lifts, etc.)
• Engine control unit (ECU) — controls engine operation
• Electrical outlets and lighter — additional consumers
• Ignition system — provides fuel-air ignition
• Charging system — maintains battery charge

Why is electrical equipment repair needed?

• Ensure engine start
• Guarantee proper operation of all vehicle systems
• Ensure road safety (lighting, signals)
• Provide vehicle comfort
• Prevent engine failure
• Pass technical inspection (ITV)

What Components Are Included in Electrical Equipment?

1. Power Generation and Storage System

This system generates and stores electrical power:

System components:

• Battery — stores electrical energy

  • Voltage: 12V (some trucks 24V)
  • Capacity: typically 40-100 Ah
  • Lifespan: 3-5 years

• Alternator — produces electrical power

  • Voltage: 13.5-14.5V with running engine
  • Power: 60 to 200 A depending on model
  • Installed on front of engine

• Voltage regulator — controls alternator output

• Alternator brushes — transmit current to rotor

• Diode bridge — converts AC to DC

How system works:

1. Running engine, alternator generates electrical power
2. Voltage regulator controls voltage level
3. Electrical power charges battery
4. With engine off, battery powers all consumers

How system works:

1. Driver turns key to START position
2. Ignition switch signals starter relay
3. Relay engages starter
4. Solenoid shifts gear onto flywheel
5. Starter rotates flywheel, starting engine
6. With running engine, free wheel disengages starter
