ASE A6 - Electrical/Electronic Systems Exam Questions with Correct Answers Latest Update
2025/2026
An air bag system is being serviced, Technician A says to disconnect the yellow SRS connectors
at the front of the vehicle. Technician B says to disconnect and isolate the negative battery
cable.
Who is right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - Answers The correct answer is B. Always disconnect the negative battery
cable and wrap with tape so contact cannot be made. Follow the specific vehicle's disarming
instructions, as some SRS system can retain backup power for an additional period of time.
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 - Answers 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 - Answers 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 - Answers 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 - Answers 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 - Answers 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 - Answers 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
C. Both A and B
D. Neither A or B - Answers The correct answer is C, both technicians are right. Both an
improperly rated flasher and an incorrect wattage bulb can cause the turn signals to flash at
incorrect intervals.
Technician A says a short circuit to ground in a circuit will decrease resistance. Technician B
says a short circuit will increase current flow. Who is right?
A. Technician A only
B. Technician B only
C. Both A and B
D. Neither A or B - Answers The correct answer is C, both technicians are right. A short to
ground has little or no resistance. Current flow increases as resistance decreases.
When using a voltmeter to check for voltage in a circuit, the voltmeter should first be connected
to check for:
A. source voltage.
B. excessive resistance
C. excessive amperage.
D. a good ground. - Answers The correct answer is A. A voltmeter should first be used to see if
the circuit is getting power before during further tests.
When checking the green eye of a sealed maintenance-free battery, no color seen indicates that
the battery is:
A. undercharged.
B. charged properly.
C. overcharged.
D. damaged. - Answers The correct answer is A. If the so-called "green eye" is not visible, the
green tip of the built-in hydrometer is not floating high enough in the electrolyte to be visible. A
