ASE G1 Maintenance & Lt. Repair Practice Test

16. The headlights get brighter as the engine is revved. Technician A says this is caused by a high capacity battery. Technician B says this is caused by a faulty voltage regulator. Who is correct?

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

16.

Answer A is wrong. The vehicle's battery is primarily used for starting the engine.

Answer B is correct. At the heart of the charging system is the alternator. If the alternator outputs excessive or high charging voltage, check voltage regulation; electrical components, and electronics will be affected.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

17. A vehicle with a power rack and pinion steering system is binding only while turning corners. Which of these are LEAST likely to cause this condition.

  • A. Strut mount bearing.
  • B. Worn rack bushings.
  • C. Worn rack and pinion gear.
  • D. Lower ball joint.

17.

Answer A is wrong. Strut mount bearings can loose vital lubrication and bind while cornering.

Answer B is correct. Worn rack bushings cause a vehicle to wander. This is a least likely type question. Notice the other three options cause binding in the steering system.

Answer C is wrong. A worn power steering rack gear can bind causing difficulty while cornering.

Answer D is wrong. A faulty or dry ball joint will result in binding while turning.

18. A technician is unable to balance a tire on a vehicle that vibrates at speeds above 35 mph. Technician A says to continue adding weights around the rim up to 10 ounces. Technician B says to dismount the tire from the rim and inspect the inside for liquid or debris. Who is correct?

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

18.

Answer A is wrong. The tire most likely has liquid or something inside. Each time the technician spins the tire, the liquid settles in a different place and a weight must be added to a different location on the rim. The technician should not just keep adding weights up to 10 ounces.

Answer B is correct. If liquid is suspected inside of a wheel, dismount the tire and inspect inside. TPMS sensors can become clogged from liquid flat repair and malfunction, resulting in a TPMS warning light.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

19. A red colored fluid is seen leaking between the transmission and the engine. Technician A says this is caused by a leaking rear main seal. Technician B says this is caused by a leaking transmission pump seal. Who is correct?

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

20.

Answer A is wrong. A leaking rear main seal will result in oil leaking between the engine and transmission bell housing. This will be tan or brown. Transmission fluid is dyed red, indicating the fluid is leaking from the transmission pump seal and not the engine's rear main seal.

Answer B is correct. A leaking oil pump seal will result in automatic transmission fluid leaking between the engine and transmission bell housing. Transmission fluid is red and oil is tan or brown colored.

Answer C is wrong. Technician B is correct.

Answer D is wrong. Technician B is correct.

Variable Resistor

20. The electrical symbol above represents:

  • A. A diode.
  • B. A variable resistor.
  • C. A fuse.
  • D. A battery.

19.

Answer A is wrong. The electrical symbol in the image is a variable resistor.

Answer B is correct. The electrical symbol in the image is a variable resistor.

Answer C is wrong. The electrical symbol in the image is a variable resistor.

Answer D is wrong. See the chart in the "Read more..." section for more symbols found in automotive electrical schematics.
