Study Notes
Electrical Systems in Automobiles
- The electrical system in an automobile provides power to various systems and devices in a vehicle, including starting the engine, powering lights, indicators, wipers, and other essential functions.
Components of Automotive Electrical Systems
- Battery: Provides electrical energy to start the engine and power electrical systems when the engine is off.
- Alternator: Converts mechanical energy from the engine into electrical energy to recharge the battery and power the vehicle's electrical systems.
- Starter Motor: Responsible for starting the engine by turning the crankshaft, located on the engine block, connected to the flywheel or flexplate.
- Wiring Harness: Connects electrical components and delivers power throughout the vehicle.
- Fuses and Relays: Protect electrical circuits from damage due to overloads and control the flow of electricity to various components.
Battery System
- Provides electrical energy to start the engine and operate electrical systems when the engine is off.
- Components: Positive and negative terminals, electrolyte, lead plates, casing, vent caps, internal cell connectors, etc.
- Operation: Chemical reactions between electrolyte and lead plates generate electrical energy.
- Maintenance: Regularly check terminals, clean corrosion, ensure proper electrolyte levels.
Lighting System
- Illuminates the road and surroundings for visibility and safety.
- Components: Headlights, taillights, brake lights, turn signals, fog lights, interior lights, etc.
- Operation: Lights are powered by the vehicle's electrical system and controlled by switches and relays.
- Maintenance: Regularly check bulbs, replace faulty bulbs, inspect wiring for damage.
Indicators, Horn, and Wipers
- Indicators signal intended direction changes, horn alerts other drivers, and wipers clear windshield for visibility.
- Components: Turn signal indicators, horn assembly, wiper blades, wiper motor, etc.
- Operation: Controlled by switches that send electrical signals to activate the respective components.
- Maintenance: Check and replace faulty switches, inspect wiper blades for wear, ensure horn functionality.
Panel Board Instruments
- Display vital information about the vehicle's performance and status.
- Components: Speedometer, tachometer, fuel gauge, temperature gauge, warning lights, etc.
- Operation: Receive electrical signals from sensors and display relevant information to the driver.
- Maintenance: Calibration of instruments, replacement of faulty sensors, check wiring connections.
Magneto Ignition System
- Generates high voltage to ignite the air-fuel mixture in the engine's cylinders.
- Components: Magneto (magnet and coil assembly), ignition coil, distributor, spark plugs, points (contact breaker), condenser, rotor, cap.
- Operation: Magnet rotation induces current in the coil, producing high voltage for spark plugs.
- Maintenance: Regular inspection and replacement of worn-out components, checking and setting spark plug gaps.
Electronic Ignition System
- Controls ignition timing and spark generation using electronic components.
