Question 3

A technician connects one lead of a digital voltmeter to the positive (+)  terminal of the battery and the other meter lead to the battery terminal (B)  of the starter solenoid and then cranks the engine. During cranking, the voltmeter displays a reading of 878 mV. Technician A says that this reading indicates that the resistance of the positive battery cable is too high. Technician B says that this reading indicates that the starter is defective. Who is right?

Accepted Answer

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

Question 4

A cranking system voltage drop test is being done. Technician A says that the higher the voltage drop, the lower the resistance in the circuit. Technician B says that a high voltage drop in the cranking circuit wiring can cause slow engine cranking. Who is right?

Accepted Answer

A)  Technician A only
B)  Technician B only
C)  Both technicians A and B
D)  Neither technician A nor BE) A) and B)
F) None of the above

Question 5

With the armature removed from the starter motor, the field coils should be tested for opens and grounds using which of these tools?

Accepted Answer

A)  Powered test light
B)  Ohmmeter
C)  Ammeter
D)  Either A or BE) All of the above
F) A) and B)

Question 6

Technician A says that proper starter operation depends on the battery being at a 95% charge and battery cables being of the correct size (gauge)  and having no more than 0.8-volt drop. Technician B says that voltage-drop testing includes cranking the engine, measuring the drop in voltage from the battery to the starter, and measuring the drop in voltage from the negative terminal of the battery to the engine block. Who is right?

Accepted Answer

A)  Technician A only
B)  Technician B only
C)  Both technicians A and B
D)  Neither technician A nor BE) A) and B)
F) None of the above B

Question 7

Which of these components is the armature?

Accepted Answer

A)  A
B)  B
C)  C
D)  DE) A) and B)
F) All of the above

Question 8

All of these can cause a starter not to rotate, EXCEPT ________.

Accepted Answer

A)  Seized engine crankshaft
B)  Defective armature
C)  Defective starter drive
D)  Shorted field coilsE) A) and B)
F) B) and C)

Question 9

Which of these tools is MOST likely to be used to determine the starter circuit voltage drop test?

Accepted Answer

A)  Voltmeter
B)  Ammeter
C)  Ohmmeter
D)  Meg ohmmeterE) A) and D)
F) B) and D)

Question 10

A voltage drop test on the starter control circuit is used to test which of these starter component(s) ?

Accepted Answer

A)  Starter solenoid and field coil
B)  Commutator
C)  Wiring and connections
D)  Field coilsE) All of the above
F) None of the above C

Question 11

Which of these can cause a starter grinding noise?

Accepted Answer

A)  Seized engine
B)  An over-tightened flywheel
C)  Neutral safety switch
D)  Defective starter driveE) B) and C)
F) A) and C)

Question 12

Technician A says that the cranking circuit should be tested for proper amperage draw. Technician B says that an open in the control circuit will not prevent starter motor operation. Who is right?

Accepted Answer

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

Question 13

What test is being performed in this illustration?

Accepted Answer

A)  Positive side voltage drop test
B)  Ground side voltage drop test
C)  Amperage draw test
D)  Battery load testE) B) and D)
F) A) and B)

Question 14

The starter motor on a V-6 engine is being tested for starter amperage draw. The initial surge current was about 210 amperes and about 160 amperes during cranking. Technician A says that the starter is defective and should be replaced because the current flow exceeds 200 amperes. Technician B says that this is normal current draw for a starter motor for a V-6 engine. Who is right?

Accepted Answer

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