Deck 28: Starting System Fundamentals

Question 1

All of the following statements are true EXCEPT:

A)power is sent to the starter relay when the key is turned to the spring-loaded "start" position.
B)some cars use the relay by itself; others use a relay to reduce the load on the neutral safety and ignition switches.
C)late-model vehicles with manual transmissions have a starter/clutch interlock switch that requires the clutch to be depressed to the floor.
D)some British cars still had Bendix drives until the late 1980s.

Answer 1

D

Question 2

____ are made of heavy copper ribbons wound around soft iron cores called pole shoes.

A)Field coils
B)Commutator bars
C)Armatures
D)Windings

Answer 2

A

Question 3

Which of the following is LEAST-Likely one of the basic parts of a motor?

A)Pole shoe
B)Crankshaft
C)Brush
D)Split ring commutator

Answer 3

B

Question 4

The ___________________ between the pinion and ring gears provides the starter with the leverage needed to turn the crankshaft against engine compression.

Question 5

Because like charges repel each other and unlike charges attract, magnetic fields can be used to cause motion.

Question 6

All of the following statements are true EXCEPT:

A)a permanent magnet starter is simpler than a conventional field coil starter.
B)a permanent magnet starter weighs more than a conventional field coil starter.
C)with no field coils, current goes directly to the armature through the commutator and brushes.
D)a permanent magnet starter creates less heat than a conventional field coil starter.

Question 7

Multiple loops make up an armature.

Question 8

The starter motor must spin at ____ rpm in order to turn the engine at normal cranking speed to start the engine, which is about 200-250 rpm.

A)1,200
B)3,600
C)4,000
D)4,500

Question 9

Cars built before the early 1960s that were equipped with a remote starter relay MOST-Likely had:

A)inertia starter drive units
B)permanent magnets
C)brushless motors
D)a positive engagement starter

Question 10

The teeth on the starter drive gear are tapered to allow for smooth engagement with the ____________________.

Question 11

A(n) ____________________ transmits motion from the starter to the flywheel, but not from the flywheel to the starter.

Question 12

The armature core is wrapped with many loops of heavy insulated copper wire called ____________________.

Question 13

While having a discussion, Technician A says that most solenoids are mounted on the top of the starter motor. Technician B says some solenoids are mounted in a remote location. Who is correct?

A)A only
B)B only
C)Both A and B
D)Neither A nor B

Question 14

The ratio between the pinion and ring gears is about 8:1.

Question 15

Which of the following is LEAST-Likely a starter driver part?

A)Drive pinion gear
B)Flywheel
C)Crankshaft
D)Capacitor

Question 16

A(n) ____________________ disengages from the engine at startup, preventing the engine from driving the starter.

Question 17

Some starter motors used since the mid-1980s have no field coils but have permanent magnets instead.

Question 18

If the starter is forced to rotate at speeds above 1,000 rpm, it could be destroyed by centrifugal force.

Question 19

Starters MOST-Likely have a part that combines a relay with a mechanical device that engages the starter drive pinion with the flywheel ring gear, called a(n):

A)armature
B)field coil
C)solenoid
D)pole shoe

Question 20

While having a discussion, Technician A says that a solenoid has contact points, whereas a relay uses a movable iron piston attached to a contact disc. Technician B says that a relay has contact points, whereas a solenoid uses a steel piston moved against a contact disc by magnetism. Who is correct?

A)A only
B)B only
C)Both A and B
D)Neither A nor B

Question 21

What is the relationship between starters and electromagnetism?

Question 22

What is the relationship between loops and the armature?

Question 23

What is the purpose of brushes on the commutator?

Question 24

What is the purpose of the starter's relay?

Question 25

What are the disadvantages of arcing in a conventional DC motor?
