Question 1:
A resistance test was performed on an open toggle switch and the result
is 5.857 megohms . Technician A says that the switch is faulty because
the reading is beyond the specifications . Technician B says that the
switch has over 5 million ohms of resistance . Who is correct ? A. A only
B. B only C. Both A and B D. Neither A nor B
Answer:
Answer A is incorrect . An open switch is supposed to have very high
resistance . Answer B is correct . Only Technician B is correct . The
reading is over 5 million ohms . An open switch should have very high
resistance . Answer C is incorrect . Only Technician B is correct . Answer
D is incorrect . Technician B is correct .
Question 2:
The 12 volt battery in the figure is fully charged and the switch is closed .
Which of the following conditions would be the most likely cause of this
measurement ? A. Larger than specified wire used in wire repair B. Loose
ground for the bulb
Answer:
Answer A is incorrect . A larger wire used in a wire repair would not cause
a voltage loss . Answer B is correct . A loose ground for the bulb could
cause a voltage loss at the ground connection . Performing a voltage
drop test on the ground circuit could isolate this problem . Answer C is
,incorrect . A blown fuse would prevent any voltage from getting past the
fuse contacts . Answer D is incorrect . There is no evidence that the bulb
is faulty . The meter shows only 9 volts being dropped across the bulb .
Question 3:
Which of the following conditions could cause the power locks to fail to
operate ? A. Broken connector at the power lock switch B. Closed power
lock circuit breaker C. An oversized fuse D. An oversized wire repair in
the power lock circuit
Answer:
Answer A is correct . A broken connector at the power lock switch could
cause the power locks to be inoperative because it would likely create an
open circuit . Answer B is incorrect . A closed power lock circuit breaker
would allow normal operation of the power door locks . Answer C is
incorrect . An oversized fuse would allow the power door locks to function
. For safety reasons , however , a technician should never install a fuse
that has a larger rating than the specification . Answer D is incorrect . An
oversized wire would not hinder the operation of the power door locks .
, Question 4:
When using a 12 volt , unpowered test lamp to test for voltage , all of the
following are true EXCEPT : A. The test lamp may be connected to the
battery ground . B. The battery should first be disconnected . C. The test
lamp may be connected to a chassis ground . D. The test lamp will not
illuminate when probed
Answer:
Answer A is incorrect . A 12 volt unpowered test lamp can be connected
to the battery ground cable or any quality ground on the truck . Answer B
is correct . The test light would not operate if the battery were
disconnected . Answer C is incorrect . A 12 volt unpowered test lamp can
be connected to the chassis ground or any quality ground on the truck .
Answer D is incorrect . The voltage level will drop to near zero at points
past the load , causing the test lamp to not illuminate if probed into this
part of the circuit.
Question 5:
After removing a 30 amp circuit breaker from a fuse panel , a technician
checks continuity across its terminals with a digital multimeter ( DMM ) .
Technician A says that the current from the ohmmeter will open the circuit
breaker . Technician B says the ohmmeter should read infinity if the
circuit breaker is good . Who is correct ? A. A only B. B only C. Both A
and B D. Neither A nor B
Answer:
Answer A is incorrect . The small amount of current supplied by an
ohmmeter would not cause a good circuit breaker to open up . Answer B
is incorrect . The ohmmeter should read low resistance on a good circuit
breaker Answer C is incorrect . Neither Technician is correct . Answer D
is correct . Neither Technician is correct . Using an ohmmeter to test a
circuit breaker will not cause the contacts to open up because the current
from the meter will be very small . A good circuit breaker will have a low
reading when being tested with an ohmmeter .
