A starter motor rotates about ________ times faster than the engine. -
CORRECT ANSWER -18
After installing the starter, the technician should perform which of the
following?
A. Check the starter for proper operation
B. Attach the negative battery cable
C. Perform a starter voltage drop test before starting the engine
D. Both A and B - CORRECT ANSWER -Both A and B
If the clearance between the starter pinion and the engine flywheel is too
great, ________. - CORRECT ANSWER -The starter will produce a high
pitched whine during cranking
,Technician A says that a discharged battery (lower than normal battery
voltage) can cause solenoid clicking. Technician B says that a discharged
battery or dirty (corroded) battery cables can cause solenoid clicking.
Which technician is correct? - CORRECT ANSWER -Both technicians
Which one of these would NOT be a diagnostic step when Diagnosing a "no
crank" customer concern? - CORRECT ANSWER -Check the condition of the
engine oil
Slow cranking by the starter can be caused by all of these, EXCEPT
________. - CORRECT ANSWER -Open neutral safety switch
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 positive battery cable has too high resistance. Technician
B says that this reading indicates that the starter is defective. Which
technician is correct? - CORRECT ANSWER -Technician A only
What is the first step for removing a starter? - CORRECT ANSWER -
Disconnect the battery negative cable
Two technicians are discussing what could be the cause of slow cranking
and excessive current draw. Technician A says that an engine mechanical
fault could be the cause. Technician B says that the starter motor could be
binding or defective. Which technician is correct? - CORRECT ANSWER -
Both technicians
, A V-6 is being checked for starter amperage draw. The Initial surge current
was about 210 amperes and about 160 amperes during cranking.
Technician A says the starter is defective and should be replaced because
the current flow exceeds 200 amperes. Technician B says this is normal
current draw for a starter motor on a V-6 engine. Which technician is
correct? - CORRECT ANSWER -Technician B only
Bench testing of a starter should be done ________.
A. After reassembling an old starter
B. Before installing a new starter
C. After removing the old starter
D. Both A and B - CORRECT ANSWER -Both A and B
A magnetic field created in the ________ is used to induce a voltage in the
________. - CORRECT ANSWER -rotor; stator
The alternator output current is produced in the ________. - CORRECT
ANSWER -Stator
How is the AC voltage produced in the alternator changed to DC voltage? -
CORRECT ANSWER -Diodes inside the alternator
Technician A says that an alternator overrunning pulley is used to reduce
vibration and noise. Technician B says that an overrunning alternator
pulley or dampener uses a one-way clutch. Which technician is correct? -
CORRECT ANSWER -Both technicians
