What is the function of the alternator in a vehicle?
Answer: To generate electrical power and charge the battery
The alternator generates electrical power and charges the battery while the engine is running, supplying electricity to various vehicle systems.
Which component is responsible for delivering power to the spark plugs?
Answer: Ignition coil
The ignition coil converts the battery’s low voltage into high voltage, providing the necessary spark for ignition.
What is a common symptom of a failing battery?
Answer: Slow engine cranking and dim headlights
A weak or failing battery can cause slow engine cranking, dim headlights, and difficulty starting the vehicle.
What does a vehicle’s fuse box protect?
Answer: Electrical circuits from overloads
The fuse box protects electrical circuits from overloading by breaking the circuit if excessive current flows through it.
Which diagnostic tool is commonly used to check vehicle electrical systems?
Answer: Multimeter
A multimeter is a versatile tool used to measure voltage, resistance, and current in electrical circuits, helping diagnose issues.
What is the primary purpose of relays in a vehicle’s electrical system?
Answer: To control high-power circuits with low-power signals
Relays act as electrically operated switches that control high-power circuits using low-power signals, improving efficiency and safety.
