Question 1

The starter drive is the part of the starter motor that engages the armature to the engine____.
A) starter solenoid
B) flywheel ring gear
C) commutator
D) clutch

Accepted Answer

The starter drive engages with the teeth on the flywheel ring gear, which is connected to the engine. The starter solenoid is responsible for initiating the starter motor, the commutator is a part of the armature, and the clutch is not directly related to the starter motor.

Question 2

The ____ test measures the electrical load of the starter when it is actuated.
A) current-draw
B) battery
C) voltage drop
D) compression

Accepted Answer

The current-draw test is used to measure the electrical load of the starter when it is actuated. It can help identify any issues with the starter system or the electrical system, such as a weak battery or a malfunctioning starter motor.

Question 3

If there is a leak that allows antifreeze from the cooling system to enter the cylinder, the cylinder can fill to such a level that the piston is unable to move upward. This condition is referred to as____.
A) hydrostatic lock
B) coolant flooding
C) no crank
D) starter ring freeze

Accepted Answer

The condition described is known as hydrostatic lock, where a liquid, in this case antifreeze, is preventing the normal movement of the engine's pistons.

Question 4

When there is no current draw and the starter does not rotate, the cause could be
A) open field windings
B) open armature coils
C) broken brushes or springs
D) All of the above

Accepted Answer

All of the above could prevent the starter from rotating when there is no current draw. Open field windings, open armature coils, and broken brushes or springs can all cause a lack of continuity and prevent the starter from functioning properly.

Question 5

Technician A says speeding up the armature will result in decreased amperage draw. Technician B says slowing down the starter armature will result in increased amperage draw. Who is correct?
A) Technician A only
B) Technician B only
C) Both Technician A and B
D) Neither Technician A nor B

Accepted Answer

Both Technician A and B are correct. Speeding up the armature reduces the electrical load, thus decreasing amperage draw, while slowing down the armature increases the electrical load, thus increasing amperage draw.

Question 6

The ____ test will isolate the problem area and determine whether the starter motor, solenoid, or control circuit is at fault.
A) battery
B) circuit
C) lab scope
D) quick

Accepted Answer

The quick test is specifically designed to isolate the problem area and determine whether the starter motor, solenoid, or control circuit is at fault. The other options (battery, circuit, lab scope) do not provide this specific diagnostic capability.

Question 7

The principle of ____ is used to convert electrical energy into mechanical energy in a starter motor.
A) inertia
B) flux density
C) electromagnetism
D) ignition

Accepted Answer

The principle of electromagnetism is used to convert electrical energy into mechanical energy in a starter motor. This is done by creating an electromagnetic field that rotates the motor's armature, which eventually leads to the engine turning over. Inertia, flux density, and ignition are not directly involved in the conversion process.

Question 8

The starter motor must be capable of ____ the engine fast enough to start and run under its own power.
A) igniting
B) charging
C) arcing
D) rotating

Accepted Answer

The starter motor's main function is to rotate the engine fast enough so that it can start and run under its own power. Therefore, the best choice is D - rotating. The other options (igniting, charging, and arcing) do not accurately reflect the function of the starter motor.

Question 9

The most common type of starter drive is the ____.
A) compound motor
B) drive pinion
C) Bendix drive
D) overrunning clutch

Accepted Answer

The answer of The most common type of starter drive...

Question 10

The integrated starter generator (ISG) is a three-phase ____ motor.
A) AC
B) DC
C) HV
D) LV

Accepted Answer

The integrated starter generator (ISG) is a three-phase alternating current (AC) motor. This is because the ISG is primarily used to start the internal combustion engine and generate electrical power during operation, which requires an AC motor.

Question 11

In any DC motor, there are three methods of connecting the field coils to the ____: series, parallel (shunt), and a compound connection that uses both series and shunt coils.
A) lamination
B) battery
C) commutator
D) armature

Accepted Answer

In a DC motor, the field coils can be connected to the armature in three ways: series, parallel (shunt), or a compound connection that combines both series and shunt coils. This configuration determines the motor's characteristics and performance.

Question 12

The starting system is designed to change the energy stored in the ____ into mechanical energy.
A) cranking motor
B) solenoid
C) starter drive
D) battery

Accepted Answer

The battery is the source of stored energy in the starting system, which is then converted into mechanical energy by the other components such as the cranking motor, solenoid, and starter drive.

Question 13

Common types of AC motors are the ____ motor and the induction motor.
A) electromagnetic
B) synchronous
C) positive-engagement
D) asynchronous

Question 14

Technician A says increasing the amount of current flowing through a conductor will increase the strength of its magnetic field. Technician B says coiling a wire around a soft iron core will increase the strength of its magnetic field. Who is correct?
A) Technician A only
B) Technician B only
C) Both Technician A and B
D) Neither Technician A nor B

Accepted Answer

Technician A is correct. Increasing the amount of current flowing through a conductor will increase the strength of its magnetic field according to the right-hand rule.

Technician B is also correct. Coiling a wire around a soft iron core will create an electromagnet with a stronger magnetic field than a single wire. This is because the soft iron core increases the magnetic field by concentrating it in a smaller area.

Question 15

As the series-wound motor speed increases, the torque output of the motor will ____.
A) decrease
B) also increase
C) cease
D) stay the same

Accepted Answer

As the speed of a series-wound motor increases, the torque output of the motor will decrease. This is because the increased speed causes increased counter-EMF (electromotive force) which reduces the net voltage across the armature windings and ultimately reduces the motor's torque output.

Question 16

Some manufacturers use a gear reduction starter to provide increased ____.
A) torque
B) current
C) magnetism
D) positivity

Accepted Answer

A gear reduction starter increases torque by using a smaller, high-speed motor to turn a larger gear which in turn rotates the engine. This allows for more torque to be produced with a smaller motor.

Question 17

Which of the following represents the correct sequence of steps that may need to be performed when testing a starting system?
A) Visual inspection, battery condition, voltage drop, starter draw
B) Visual inspection, voltage drop, battery condition, starter draw
C) Battery condition, visual inspection, starter draw, voltage drop
D) Visual inspection, battery condition, starter draw, voltage drop

Accepted Answer

The correct sequence of steps for testing a starting system is to first perform a visual inspection of all components, then check the battery condition, followed by checking the starter draw, and finally checking for voltage drop. This sequence ensures that any visual issues or obvious faults are addressed first before moving onto more specific tests of the components. Therefore, option D is the correct choice.

Question 18

Technician A says the neutral safety switch can apply a ground to the starter relay. Technician B says the neutral safety switch can also control the back-up lights on a vehicle. Who is correct?
A) Technician A only
B) Technician B only
C) Both Technician A and B
D) Neither Technician A nor B

Accepted Answer

Technician A is correct that the neutral safety switch can apply a ground to the starter relay. Technician B is also correct that the neutral safety switch can control the back-up lights on a vehicle. Therefore, both Technician A and Technician B are correct.

Question 19

Technician A says the commutator is a series of conducting segments located around one end of the armature that come in contact with the brushes. Technician B says the armature is the stationary component of the motor that consists of a conductor wound around a pole shoe. Who is correct?
A) Technician A only
B) Technician B only
C) Both Technician A and B
D) Neither Technician A nor B

Accepted Answer

Technician A is correct. The commutator is a series of conducting segments located around one end of the armature that come in contact with the brushes.

Technician B is incorrect. The armature is not a stationary component, but rather the rotating component of the motor that consists of a conductor wound around a pole shoe.

Question 20

Most modern vehicles will use a starter _____ in conjunction with a starter motor-mounted solenoid to control starter motor operation.
A) recombination battery
B) series circuit
C) relay
D) hold-in winding

Accepted Answer

A relay is an electrical switch that uses an electromagnet to open or close a switch contact when a low voltage is applied. In this case, the starter relay is used to control the high current flow to the starter motor by switching the circuit on and off. The hold-in winding (D) is a component of the solenoid, and a series circuit (B) refers to the electrical connectivity of components in a circuit, neither of which are used as the primary control for starter motor operation. A recombination battery (A) is not relevant to the question.
