ase exam questions and answers

A technician is performing a load test on a battery and finds the battery to below specifications. Which of the following is the best action to taken next? a Perform a resistance test on the battery b Recharge the battery and sell it as a used battery c Recharge the battery and retest it d Drain the battery completely and recharge it c Recharge the battery and retest it Two technicians are discussing a whining noise heard through the radio. Technician A says a faulty alternator stator can cause the problem. Technician B says a faulty diode is most likely the cause. Who's correct? Tech A Tech B Both A and B Neither A nor B Both A and B Technician A says to pull a fusible link from both ends to check and see if the link has broken. Technician B says to pierce the wire with your DVOM test leads to check the link. Who's correct? Tech A Tech B Both Neither Tech A Two technicians are talking about repairing a dash circuit board. Tech A states a 60/40 solder with no flux is recommended. Tech B states a Rosin core solder is recommended. Who's correct? Tech A Tech B Both Neither Tech A A no crank job is sent to your service bay. Tech A says to check if the motor is locked up by hand turning the crank shaft pulley nut. Tech B says to check the battery condition. Which is the proper first step? Tech A Tech B Both A and B Neither A nor B Tech B Two technicians are talking about intermittent headlamp problems. Tech A says the most common problem is loose or corroded ground connections. Tech B says aftermarket headlights don't last as long as factory lights do. Who's correct? Tech A Tech B Both A and B Neither A nor B Tech B Tech A says that the off gasses from a charging battery are mainly hydrogen and are explosive. Tech B says they are mainly toxic and are not explosive. Who's correct? Tech A Tech B Both Neither Tech A Technician A states that a flooded battery uses anti-acids in a hydrochloric solution to maintain a battery charge. Technician B states a flooded battery has 90% sulfuric acid in the solution to maintain the battery charge. Who's correct? Tech A Tech B Both Neither Neither Name three different ways to load test a battery. Conductance, Carbon Pile, and using the starter motor Carbon Pile, Brake lights, and Hand held tester Conductor, Graphing, and Carbon Pile None of the above Conductance, Carbon Pile, and using the starter motor Tech A says a parasitic draw is a temporary drain on the battery. Technician B says that a parasitic draw can shorten the life of a battery. Who's correct? Tech A Tech B Both Neither Tech B Two technicians are examining a low charge output on a vehicle. Tech A says if the battery is defective it can block the output of the alternator. Tech B says that a defective stator could be the cause. Who's correct? Tech A Tech B Both Neither Both A vehicle enters the service bay with an extremely noisy alternator. Which of the following is LEAST likely to be the cause. Worn alternator brushes loss of ground Scored alternator bearings Loose serpentine belt Defective diodes Worn alternator brushes Charge output on most vehicles ranges from: 12.6 to 13.5 volts 14.2 to 16.5 volts 12 to 14 volts 13.5 to 15.0 volts 13.5 to 15.0 volts On today's vehicles most alternators are not directly connected to the charge light in the dash. What is the charge light connected to then? Bridge rectifier To the voltage regulator To the lighting control module To the PCM To the PCM Technician A says that a corroded connection can be the source of a voltage drop. Technician B says that a voltage drop can only be on the ground side of a circuit. Who's correct? Tech A Tech B Both Neither Tech A
