ASE T6 TEST |ACTUAL QUESTIONS AND VERIFIED
ANSWERS|BRAND NEW 2026-2027
UPDATE|GRADED A+
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
CORRECT 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
C. Blown fuse
D. Faulty bulb
CORRECT ANSWER
1
,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
CORRECT 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 .
2
, 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 into the circuit at a point after the load .
CORRECT 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
CORRECT 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 .
