Exam 6: Starting Systems and Motor Designsstarting System Diagnosis and Service

The integrated starter generator (ISG) is a three-phase ____ motor.

Describe how the rotor turns in a three phase AC motor.

The ring gear teeth of a flywheel are badly worn in various spots. Technician A says this could cause poor drive gear engagement. Technician B says this could cause a lower-than-normal starter current draw. Who is correct?

A tighter-than-normal engine will decrease the amperage draw of the system.

Which of the following statements is true of solenoids?

Define the current draw test.

Common types of AC motors are the ____ motor and the induction motor.

Slower-than-normal speed and higher-than-normal cranking amperage is usually the result of internal starter problems.

The two windings in the solenoid are the pull-in and the hold-in.

The most common type of starter drive is the ____.

The commutator should be cleaned with ____.

What part of the starter motor engages the armature to the engine flywheel (flexplate) ring gear?

List the possible causes of excessive resistance to rotation.

A starter should draw less current once it is spinning.

Technician A says the two windings of the solenoid are called the pull-in and the hold-in windings. Technician B says both windings of the solenoid are continually energized any time the ignition switch is in the start position and the starter motor is spinning. Who is correct?

In any DC motor, there are three methods of connecting the field coils to the ____: series, parallel (shunt), and a compound connection that uses both series and shunt coils.

Describe how performing a "relative compression test" using a lab scope and the starting circuit can determine internal engine condition.

A vehicle is being checked for a no-crank condition. A voltmeter placed across the contacts of the starter solenoid indicates 12 volts when the ignition is turned to the "start" position. A distinct "click" noise is heard coming from the solenoid at the same time. Technician A says the starter motor may have an open armature or field current. Technician B says the starter solenoid needs to be replaced. Who is correct?

Vehicles equipped with manual transmissions have a clutch safety switch.

If there is a leak that allows antifreeze from the cooling system to enter the cylinder, the cylinder can fill to such a level that the piston is unable to move upward. This condition is referred to as____.
