ASE G1 Maintenance & Lt. Repair Practice Test

31. Maintenance-free batteries have a built-in hydrometer that indicates the battery's state of charge. Technician A says to add distilled water to the battery if the charge indicator turns dark green or black. Technician B says a fully charged battery has a light green charge indicator. Who is correct?

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

31.

Answer A is wrong. We do not typically add distilled water to a maintenance-free battery. It’s sealed and contains either a gel or a glass fiber mat instead of the liquid solution found in standard batteries.

Answer B is correct. A bright green charge indicator indicates a charged battery.

Answer C is wrong. They have relief valves that prevent pressure buildup.

Answer D is wrong. Technician B is correct.

32. Technician A says to check the circuit's fuse if the actuator is not receiving power. Technician B says if a 15 amp fuse continues to blow, replace it with a 20 amp fuse for added protection. Who is correct?

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

32.

Answer A is correct. A fuse protects a circuit by providing a weak point that will burn open before a sensitive wire or component does.

Answer B is wrong. Replacing a fuse with one of a higher rating is not recommended and will compromise and overload the circuit. If a fuse keeps blowing, suspect a short somewhere in its circuit.

Answer C is wrong. Technician A is correct.

Answer D is wrong. Technician A is correct.

33. A front-wheel-drive vehicle makes a clicking noise that only occurs while cornering. The technician suspects a faulty front axle. Which of these is the cause?

  • A. The inner CV joint.
  • B. The outer CV joint.
  • C. The vibration damper.
  • D. The half shaft is bent.

33.

Answer A is wrong. A faulty inner CV joint makes the most noise during initial acceleration.

Answer B is correct. A faulty or worn outer CV joint makes its most noise while cornering.

Answer C is wrong. The damper prevents high speed vibration.

Answer D is wrong. A bent axle will cause a vibration that increases with vehicle speed. Worn outer CV joints are notorious for clacking and popping while turning.

34. The tread of a tire is worn in the center and not on the outer shoulders. Technician A says this is caused by an improper wheel alignment angle. Technician B says this is caused by overinflating the tire. Who is correct?

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

34.

Answer A is wrong. This is caused by an overinflated tire.

Answer B is correct. An overinflated tire wears the center of the tire's tread, and an underinflated tire wears the outside edges or shoulders.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

35. All of the following are true about using a multimeter to test a circuit’s continuity EXCEPT:

  • A. Set the multimeter to the Ohms setting.
  • B. Turn the ignition on and power the circuit before testing.
  • C. A reading of OL indicates an open circuit.
  • D. A reading of 0.3 Ohms indicates continuity.

35.

Answer A is wrong. This is an EXCEPT type question. Set the multimeter to the Ohms setting.

Answer B is correct. Don't power the circuit before testing; an ohmmeter passes a small amount of current through the device or wire being tested. It then measures the resulting voltage.

Answer C is wrong. Answer B is correct.

Answer D is wrong. Answer B is correct.
