Exam 8: Charging Systems

Technician A says that Intelli-check is best used as a first-level diagnostic tool.Technician B says that if Intelli-check illuminates one of the four failure indicator LEDs,it would be good practice to have a technician skilled in electrical systems to check the system before replacing components.Who is correct?

Technician A says that the Delco-Remy Intelli-check instrument can pin-point difficult to diagnose,charging circuit problems.Technician B says that an Intelli-check test procedure produces one of 5 status outcomes after testing.Who is correct?

How is field current routed through an alternator?

Which of the following alternator failures could result in undercharging?

How many windings should a typical truck alternator stator have?

How are the stator windings in a typical truck alternator configured?

Which of the following defects could result in an undercharged battery?

Which of the following statements about the diagnostic practice of full-fielding an alternator is true?

Which of the following describes the role of a rectifier in an alternator?

Technician A says that a 100 amp alternator can draw as much as 7 horsepower from the engine.Technician B says that an alternator is switched in and out of its effective cycle by the voltage regulator.Who is correct?

If you do not apply an electrical load to the batteries when full-fielding an alternator,which of the following could result?

Technician A says that to perform a maximum output test on a typical heavy-duty truck charging circuit,the engine should be run at 1500 rpm.Technician B says that alternator rpm is typically at least three times engine rpm.Who is correct?

Which of the following conditions will shorten the life of batteries?

Technician A says that a Delco/Remy 55 SI alternator rated at 420 amps is often used in motor coach applications.Technician B says that a Delcotron 33/34 SI can be rated as high as 300 amps.Who is correct?

What specific component on a truck charging system does an AC leakage test evaluate?

Which of the following best explains how an alternator is driven by truck engine at a higher speed than engine rpm?

Which of the following statements about how electrical current flow is induced in an alternator is correct?

When testing a Delcotron 33/34 SI alternator at an ambient temperature of 80 degrees Fahrenheit,what would be a within specification field current draw?

Technician A says that to perform an AC leakage test,a DMM should be set to auto-range AC with one test lead placed on the alternator insulated terminal,and the other on chassis ground.Technician B says that when performing an AC leakage test,the engine should be run at 1500 rpm.Who is correct?

What is the function of the diode trio in an internally regulated truck alternator?
