ASE Electrical Test T6 (Practice Questions)

[mikesativa]

Hello fellow auto enthusiasts, I'm currently attending a Diesel/Heavy Duty Equipment tech school.

I'm getting ready to certify by taking a reputible electrical test and thought I would see if anyone was interstested a practice thread for this test.

I will add a few questions each day and give the answers and the reasons on the following day.

By show of hands, who is intersted in preparing for this exam with me? Serious people only who actually want to learn and take the exam. Either now or later. Thanks for checking out my post and lets keep this thread clean.

Put the question number(s) and answer(s) on the FIRST line of your post.

Ok, here the first set of questions. I'm going to number these according to my notes so I may skip a few numbers. I will just make it easier on me.

3. Which of the following is NOT used when checking a circuit for continuity?
A. An ohmmeter
B. An ammeter
C. A voltmeter
D. A test lamp

4. After removing a 30-amp circuit breaker from a fuse panel a technician checks continuity across its terminals with a digital multimeter (DMM). Tech A says that the current from the ohmmeter will open the circuit breaker. Tech B says the ohmmeter should read infinity when the circuit breaker is good. Who is right?
A. a
B. b
C. both
D. Neither

5. while diagnosing a truck with electronic engine management and a 'no-start' complaint, tech A says you should only use a DMM to check voltages on a control module circuit. Tech B says that the DMM should have a 10 megohm or higher impedance. Who is right?
A. a
B. b
C. both
D. Neither

Put the question number(s) and answer(s) on the FIRST line of your post. Thanks for looking.

It's a little early to post the answers so I'll just put up some more questions and hopefully get a few of you to participate.

7. when using a voltmeter to perform a voltage drop test in a circuit, the leads should be connected in what way?
A. to the battery terminals.
B. From the positive battery terminal to ground.
C. In seriew with the circuit being tested.
D. In parallel with the circuit being tested.

9. Tech A says an ammeter should be used to check for a short circuit between circuits. Tech B says to make sure you fully charge the battery before checking a circuit for current draw. Who is right?
A. a
B. b
C. both
D. Neither

11. Tech A says an ammeter is used to test continuity. Tech B says an ammeter indicates current flow in a circuit. Who is right?
A. a
B. b
C. both
D. Neither

13. The blower motor in a truck is running very slowly. An ammeter shows a low-current flow. This could be caused by:
A. High resistance in the circuit.
B. low resistance in the circuit.
C. an overcharged battery.
D. a shorted blower motor.

while i'm not going to take the ASE tests i can't pass up a good quiz. maybe it will prompt a few more responses as well.

3. B
4. D
5. D while it is best to use a DMM on circuits with active electronics, when performing voltage measurements an analogue volt meter is a passive device. however, do not use the continuity or resistance measurement setting of an analogue multimeter to measure continuity or resistance on a circuit that employs active componets for fear of dammaging the circuit or erraneous readings. analogue multimeters supply a higher voltage and amperage to the circuit being tested which could bias power transistors and FET's into a conductive state or possibly dammage the surface mount variety, and most IC's don't take well to over voltage conditions.
7. D
9. B i think i'd perfer to use a continuity tester to check for a short between two circuits (to prevent further dammage) and that cource of action would make the battery's state of charge irrelevant. i once heard a saying, "the more you study for a test, the more you will wonder which anwser they want."
11. B
13. A

Answers:

3. B
4. D
5. C
7. D
9. B
11. B
13. A

3. Answer B is correct because although a person could use an ammeter to check continuity, it is very impractical to do so. The other three choices are much better tools for checking continuity. An ammeter is used primarily to check for the amount of current flow.

4. Answer A is wrong because a DMM cannot generate anywhere near 30 amps of current when using the ohmmeter function.
Answer B is wrong because if a circuit breaker of fuse is good, the ohmmeter should show a very low reading (near zero), no infinity, which would indicate an open circuit.
Answer D is correct cause both technicians are wrong.

5. Answer A is a good choice, because only a DMM is an appropriate tool to use for testing voltages in an electronic circuit. However since tech B is also correct A is wrong.
Answer B is also a good choice, because a DMM should have a minimum of 10 megohms impedance to prevent it from significantly altering a circuit's measurable parameters. since tech A is also correct, B is wrong.

7. Answer D is correct because voltage drop tests are always performed by probing the leads in parallel with the component being tested.

9. Answer B is correct because low battery voltage will cause reduced current flow in the circuit with constant resistance. (Ohm's Law)

11. Answer B is correct because the sole purpose of an ammeter is to measure current flow.

13. Answer A is correct because increased resistance in a circuit with constant battery boltage will cause reduced current flow (Ohm's Law)

15. Technician A says that unwanted resistance in an electrical circuit will always produce heat. Tech B states that unwanted resistance will cause reduced current flow. Who is right?
A. a
B. b
C. both
D. Neither

17. When using a 12V test lamp to test for boltage, 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. a weatherproof connector may be backprobed.

20. A customer has a truck towed to the shop and says that the starter would not crank the engine. What should be checked first?
A. Ground cable connection
B. the starter solenoid circuit
C. The ignition switch crank circuit
D. The battery for proper charge

21. When performing a battery drain test, trhe ignition switch should be in the:
A. accessory position
B. run position
C. crank position
D. off position

You may want to check with ASE before using their name and test designation on a public forum. They are very jealous about thier proprietary rights.

P.S. Amperage Flow is a function of continuity. What circuit being tested and what the symptoms are determine the tool used for diagnosing the problem. If this is a test question, it should be noted that not all of their questions relate entirely to the real world.

I'm not using any material or questions that are from ASE. I simply wanted a place to keep me motivated to study and make sure I pass the exam, hopefully find a study partner or two. If any members feel I am infringing on their proprietary rights, I would surely like to hear about it and I will end this topic or at least edit the title.
