ASE A6 Electrical and Electronic Quiz

1. A vehicle's factory alarm system activates on its own. Technician A says this could be a faulty courtesy light switch. Technician B says the alarm system's control module uses current sensitive switches. Who is correct?
Electrical symbol
2. The electrical symbol above is:
3. Two technicians are discussing a battery that discharges overnight, even after it's been fully charged the day before. Technician A says this could be a slow drain caused by a faulty alternator. Technician B says this is most likely caused by a parasitic drain. Who is correct?
Glove box lamp circuit.
4. The lamp in the glove box does not operate. The test light is illuminated at point C with the glove box open and the switch closed. The inoperative lamp is caused by:
5. An alternator output test is being performed on a vehicle's charging system. Technician A says engine idle must be increased during this test. Technician B says the vehicle's accessories must be turned on during this test. Who is correct?
6. A technician is performing a starter current draw test on a four cylinder engine. The engine cranks slowly and has a current draw of 340 amps. Which of these is correct?
7. A power antenna is inoperative. The technician replaces the recommended 15 amp fuse and the element melts immediately. Technician A says this could be caused by a short circuit. Technician B says to use a 20 amp fuse to protect this circuit. Who is correct?
8. The driver's power window moves very slowly and the window switch must be pressed several times to open or close the window. All of these could cause this problem EXCEPT:
Parking Brake Circuit
9. The parking brake warning light in the diagram is continuously illuminated. Which of these is MOST likely the cause?
10. Technician A says to use the scan tool's datastream to evaluate input from the (ECT) engine coolant temperature sensor. Technician B says to use a scan tool to analyze input from a fuel gauge that reads full at all times. Who is correct?
Heated Seat Circuit
11. There’s an open at point A in the heated seat circuit above. Technician A says this will only affect the heating element in the backrest. Technician B says the two heating elements are part of a parallel circuit. Who is correct?
12. Technician A says changing the field current changes the alternator's voltage output. Technician B says the control module adjusts voltage regulation according to battery temperature and voltage. Who is correct?
13. A technician is looking for the wire to an airbag sensor. The color of this airbag sensor's wire is MOST likely:
14. The body ground cable is bubbled and blistering. Which of the following is correct?
15. A vehicle's engine will not crank. Technician A says to check the starter circuit first. Technician B says to check the condition of the battery first. Who is correct?
Starter voltage drop test.
16. A vehicle's engine is slow cranking. The battery has 12.6V and is in good condition. A voltage drop test is performed to test the starter circuit. Technician A says the test result above indicates there is excessive resistance in this circuit. Technician B says the ignition must be disabled and the starter cranked in order to perform this test. Who is correct?
Electrical symbol
17. The electrical symbol above is :
18. An alternator suffers from low voltage output. The alternator outputs maximum voltage when full-fielded. Which of the following is MOST likely at fault?
19. Technician A says a fully charged lead acid automotive battery has a specific gravity of 1.265 at 80° F. Technician B says the battery's specific gravity is affected by temperature. Who is correct?
20. A vehicle's air conditioner blower motor will only work if the selector is in the high position. Technician A says to check the blower motor resistor. Technician B says this is most likely a loose ground connection. Who is correct?
