  • A. Rosin Core
  • B. Silver
  • C. Zinc
  • D. Acid Core

16.

Answer A is correct. Rosin core solder is non-corrosive.

Answer B is wrong. Silver solder is best for brazing.

Answer C is wrong. Zinc can have a corrosive effect on certain metals.

Answer D is wrong. Acid core solder is usually used on pipes.

Voltage drop test

17. Which of the following statements are true about the diagram illustrated above.

  • A. It is a schematic of an alternator.
  • B. It contains 12 diodes and 4 resistors.
  • C. Both A and B
  • D. Neither A or B
Schematic diagram of an alternator circuit.

17.

Answer A is wrong. It is a schematic of an alternator.

Answer B is wrong. It contains 12 diodes and 4 resistors.

Answer C is correct. Both A and B are correct.

Answer D is wrong. Both A and B are correct.

18. Technician A says a voltage limiter is used in an instrument panel to keep the voltage at 5 volts. Technician B says if the limiter is faulty, it may result in high gauge readings. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

18.

Answer A is wrong. A voltage limiter keeps the voltage at or around 5 volts.

Answer B is wrong. A faulty voltage limiter results in high gauge readings.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.

Multimeter reading

19. The display on the multimeter indicates:

  • A. .016 Ohms
  • B. .016 Volts
  • C. 16 Ohms
  • D. 16 Volts

19.

Answer A is wrong. The multimeter indicates 16 Ohms.

Answer B is wrong. The multimeter indicates 16 Ohms.

Answer C is correct. The multimeter indicates 16 Ohms.

Answer D is wrong. Answers C is correct because K equals kiloohms or x1000.

Oscilloscope TP Sensor waveform

20. Two technicians are discussing the waveform in the image above. Technician A says the TP sensor in the image is defective. Technician B says the vehicle may hesitate during acceleration. Who is correct?

  • A. Technician A
  • B. Technician B
  • C. Both A and B
  • D. Neither A or B

20.

Answer A is wrong. Both technicians are correct.

Answer B is wrong. Both technicians are correct.

Answer C is correct. The waveform indicates a sudden drop in voltage part way through the sweep. The waveform should be smooth with no drops in voltage. This problem will cause a hesitation while accelerating.

Answer D is wrong. Both technicians are correct.
