Question 1

A starter can be constructed in a smaller size due to the use of ________ and permanent magnets.&#10;A)Single brushes&#10;B)Gear reduction&#10;C)Thinner oil&#10;D)Palm oil

Accepted Answer

Gear reduction allows for the construction of smaller starters by reducing the speed of the engine crankshaft, which in turn requires less power from the starter motor. Permanent magnets contribute to size reduction by providing a strong magnetic field without the bulk of traditional electromagnets.

Question 2

On a vehicle equipped with a stop/start system, the engine stops when the vehicle is stopped at a traffic light and then restarts when the driver releases the ________.&#10;A)Accelerator pedal&#10;B)Brake pedal&#10;C)Parking brake&#10;D)Seat belt

Accepted Answer

The engine in a vehicle with a stop/start system restarts when the driver releases the brake pedal, signaling the intention to move.

Question 3

The overrunning clutch (starter drive) accomplishes which of the following?&#10;A)Lets the starter motor rotate in either direction&#10;B)Protects the starter motor from spinning too rapidly&#10;C)Brings the starter motor into contact with the ignition circuit&#10;D)Separates the starter motor from the starter solenoid

Accepted Answer

The overrunning clutch in a starter drive protects the starter motor from spinning too rapidly by disengaging the starter gear from the engine flywheel once the engine starts and its speed exceeds that of the starter motor. This prevents damage to the starter motor from excessive speed.

Question 4

Which brushes are not insulated?&#10;A)No brushes are insulated&#10;B)Power&#10;C)Ground&#10;D)None of these

Accepted Answer

Ground brushes are not insulated because their purpose is to maintain a safe electrical connection to the ground, ensuring any excess electricity is safely dissipated into the earth, rather than causing damage or posing a safety risk.

Question 5

How many brushes are typically used in the automotive starter?&#10;A)8&#10;B)2&#10;C)4&#10;D)None of these

Accepted Answer

Automotive starters typically use 4 brushes. This configuration helps in efficiently transferring electrical current to the armature to start the engine.

Question 6

Most remote start systems will shut off the engine after ________ minutes unless reset by the remote fob.&#10;A)10&#10;B)30&#10;C)5&#10;D)None of these

Accepted Answer

Most remote start systems are designed to shut off the engine after 10 minutes to conserve fuel and reduce emissions unless the system is reset by the remote fob.

Question 7

Which safety device is used on vehicles with manual transmissions?&#10;A)Neutral safety switch&#10;B)Clutch safety switch&#10;C)Both A and B&#10;D)Neither A nor B

Accepted Answer

A clutch safety switch is used on vehicles with manual transmissions to ensure the clutch pedal is fully depressed before starting the engine, preventing accidental movement.

Question 8

On a vehicle with computer-controlled starting, some key-operated ignition systems, and most Push-button-to-start systems use the PCM to crank the engine. The ignition switch start position or the push-to-start button is used as a(an) ________ signal to the PCM.

A)Input
B)Output
C)Relay
D)Control

Accepted Answer

The ignition switch start position or the push-to-start button sends a signal to the Powertrain Control Module (PCM), acting as an input signal. The PCM then processes this information to control the starting process.

Question 9

Technician A says that the starter control circuit includes the ignition switch, neutral safety (clutch) switch, and solenoid. Technician B says that the power circuit includes the battery, battery cables, solenoid, and starter motor. Who is right?

A)Technician A only
B)Technician B only
C)Both technicians A and B
D)Neither technician A nor B

Accepted Answer

Both statements are correct. The starter control circuit indeed involves components like the ignition switch, neutral safety (clutch) switch, and solenoid as mentioned by Technician A. Technician B is also correct in stating that the power circuit includes the battery, battery cables, solenoid, and starter motor, as these components are responsible for delivering the electrical power necessary to start the engine.

Question 10

Which starting system component uses a small amount of current to control a large amount of current?&#10;A)Starter brushes&#10;B)Starter drive&#10;C)Starter solenoid or relay&#10;D)Neutral safety switch

Accepted Answer

The starter solenoid or relay uses a small amount of current from the ignition switch to control a large amount of current needed to operate the starter motor. This allows the vehicle's starting system to function efficiently by controlling the high current flow to the starter motor with a much smaller current triggered by the vehicle's ignition switch.

Question 11

The instant the ignition switch is turned to the start position, ________.&#10;A)Both the pull in winding and the hold in winding are energized&#10;B)The starter motor starts to rotate before energizing the starter pinion gear&#10;C)The hold in winding is energized&#10;D)The pull in winding is energized

Accepted Answer

The answer of The instant the ignition switch is turned...

Question 12

The starter motor can produce up to ________ horsepower.&#10;A)5&#10;B)8&#10;C)20&#10;D)None of these

Accepted Answer

The answer of The starter motor can produce up to...
