ASE A6 Electrical Electronics Practice Test

56. A vehicle's battery is being tested for capacity. Technician A says during a battery capacity test the voltage should not drop below 9.6 volts at 70° F. Technician B says a battery's voltage reading should increase as temperature decreases. Who is correct?

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

56.

Answer A is correct. If the capacity voltage drops below 9.6v at 70° F the battery may need to be replaced. The test duration is 15 seconds because any longer can damage the tool.

Answer B is wrong. The voltage reading gets lower as the outside or ambient temperature drops.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.

57. There is an NTC negative temperature coefficient sensor in the heated seat circuit above. Technician A says the resistance of this sensor decreases as the temperature of the seat increases. Technician B says the two heating elements run in series with each other. Who is correct?

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

57.

Answer A is wrong. Both technicians are correct. It’s an NTC or negative temperature coefficient sensor; the resistance of this sensor decreases as the temperature of the seat increases. This changes the voltage signal sent to the controller.

Answer B is wrong. These two heating elements run in series with each other. An open in this wire will disable both elements.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Learn more about this circuit in the read more section.

Automotive electrical symbol.

58. The electrical symbol in the illustration above indicates.

  • A. Twisted pair wire.
  • B. A heating element.
  • C. Wire insulation.
  • D. Shielded wire.

58.

Automotive electrical symbol.

Answer A is wrong. This is the symbol for shielded wire.

Answer B is wrong. Shielding a wire protects it from outside interference.

Answer C is wrong. Wire insulation also protects the signal.

Answer D is correct. CAN networks use shielded wire. The shield is often a piece of foil that protects the signal’s integrity.

59. Technician A says that the charge indicator of a maintenance free battery is a hydrometer measuring the density of the electrolyte solution. Technician B says that as the battery is discharged the electrolyte solution’s specific gravity gets closer to 1.0. Who is correct?

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

59.

Answer A is wrong. The charge indicator is a small hydrometer found in many maintenance free batteries.

Answer B is wrong. As a lead acid battery discharges its electrolyte solution gets closer to water or 1.0.

Answer C is correct. Both technicians are correct.

Answer D is wrong. Both technicians are correct.

60. The windshield wipers on a vehicle are slow and dragging across the windshield. Technician A says this could be an open circuit at the motors ground. Technician B says the wiper linkage may be binding. Who is correct?

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

60.

Answer A is wrong. The windshield wipers would be inoperable.

Answer B is correct. Binding linkage will cause the wipers to drag.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.
