Which of the following component is NOT a part of the starting system?

• Voltage regulator

• Solenoid

• Armature

• Brush

What is the primary function of the starter solenoid?

• Energize the ignition switch circuit

• Energize the starter motor

• Push the pinion gear to mesh into the ring gear

• Both energize the starter motor and push the pinion gear to mesh into the ring gear

What is the primary function of the brushes?

• Clean inside the starter motor

• Supply voltage to the solenoid

• Supply voltage to field windings

• Supply voltage to armature

What is the primary function of the neutral safety switch?

• To minimise the current draw while cranking

• To minimise the voltage drop while cranking

• To prevent cranking while engine is running

• To prevent cranking while the transmission is in gear

Metalic grinding noise is heard while cranking. What is the likely cause?

• Damaged pinion and ring gear

• Discharged battery

• Faulty solenoid

• Faulty neutral safety switch

Starting system diagnosis with headlight test is carried out. You confirmed starter motor is not cranking and headlight dimmed out. What is the likely cause?

• Damaged pinion and ring gear

• Discharged battery

• Faulty solenoid

• Faulty neutral safety switch

Starting system diagnosis with headlight test is carried out. You confirmed starter motor is not cranking and headlight reamin bright. What is the likely cause?

• Damaged pinion and ring gear

• Discharged battery

• Faulty solenoid

• Faulty neutral safety switch

Voltage drop test is carried out between battery positive and starter motor main power supply. Voltmeter shows 2.5V during cranking. What does this indicate?

• Discharged battery

• Excessive resistance in power supply circuit

• Excessive resistance in ground earth circuit

• Excessive resistance in the starter motor

Voltage drop test is carried out between battery negative and starter motor main housing. Voltmeter shows 2.5V during cranking. What does this indicate?

• Discharged battery

• Excessive resistance in power supply circuit

• Excessive resistance in ground earth circuit

• Excessive resistance in the starter motor
