ASE A6 COMPREHENSIVE EXAMINATION
TEST COMPLETE QUESTIONS WITH
ACCURATE SOLUTIONS
●● Which of these should be used when soldering electrical wiring
connections?
A. Rosin core flux
B. Acid core flux
C. Sulfur core flux
D. None of the above
Answer: The correct answer is A. For best results and less corrosion at
the solder point, a rosin core flux should be used.
●● When testing computer-controlled systems, a digital multimeter
should be used with an input impedance of at least:
A. 10k ohms
B. 100k ohms
C. 1 megohm
D. 10 megohms
Answer: The correct answer is D. For maximum protection to the
computer-controlled system, or any electronic circuit, it is best to use at
least a 10-megohm impedance digital multimeter.
,●● When troubleshooting a slow drain on the battery, which of these
diagnostic tools should be used?
A. Ohmmeter
B. Ammeter
C. Voltmeter
D. Test light
Answer: The correct answer is B. Always us an ammeter or a low
amperage amp clamp with your DMM to troubleshoot a slow drain in an
electrical circuit.
●● The condition of a lead-acid battery is being checked. Technician A
says to use a galvanometer. Technician B says to use a capacitive battery
tester. Who is right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B
Answer: The correct answer is B. A galvanometer is an analog type
voltmeter. OEMs almost universally recommend the use of a non-
intrusive conductive-capacitive type battery tester.
●● While testing a starting circuit on a 5.7L V8 engine, the technician
finds that the engine cranks slowly. The starter current draw is 90 amps,
and the battery voltage while cranking is 11 volts. What should the
technician do next?
, A. Check voltage drop of the starter motor circuit
B. Test the battery capacity
C. Replace starter motor, as a short is indicated
D. Determine condition of the engine
Answer: If an engine cranks slowly and the starter current draw is only
90 amps and the voltage is as high as 11 volts, the technician should next
check for excessive voltage drop in the start motor circuit.
●● Technician A says that a noisy alternator could be caused by a bad
diode. Technician B says that a noisy alternator could be caused by a
worn bearing. Who is right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B
Answer: The correct answer is C, both technicians are right. Worn
alternator bearings and/or a bad alternator diode will cause the alternator
to be noisy.
●● A vehicle's turn signals flash too slowly. Technician A claims that the
condition could be caused by a faulty flasher. Technician B says that a
bulb may be the wrong type. Who is right?
A. Technician A only
B. Technician B only
