Question 4

1)Some starter tests are done on an engine that still cranks over.

Question 5

4)When there is high resistance in a battery cable or its connections, they will become hot to the touch.

Question 6

20)Solenoids and starter relays used on computer-controlled vehicles have an internal ____________________ to provide protection from voltage spikes that occur when the magnetic field in the relay collapses.

Question 7

17)On the General Motors starter, the drive unit is held in place on the ____________________ shaft by a split metal ring covered by a full round ring.

Question 8

2)The biggest cause of starter motor failure is high battery voltage.

Question 9

9)While having a discussion, Technician A says that when there is a combination of slow cranking speed and lower than normal cranking amperage, the starter will need to be removed. Technician B says that the starter does not need to be removed as it can be fixed. Who is correct?

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

Question 10

12)A typical solenoid pull-in winding will MOST-Likely draw ____.

A) 35 amps
B) 72 amps
C) 104 amps
D) 115 amps

Question 11

19)Before you replace a starter drive with a new one, count the number of ____________________ on the drive pinion and match up the old and the new ones to see that they are the same.

Question 12

11)All of the following statements are true EXCEPT:

A) a voltage drop test is a fast way of determining the integrity of a connection.
B) voltage drop should be greater than 0.1 volt per connection.
C) a connection without visible corrosion can still have high resistance.
D) it is likely that a connection that appears to be corroded is adding unwanted resistance to the circuit.

Question 13

6)When the battery is weak, the part that can MOST-Likely make a series of rapid clicks is the:

A) radiator
B) ferrule
C) solenoid
D) union

Question 14

18)When replacing a starter drive, be sure to inspect the starter ring gear for damage, especially if the starter drive ____________________ shows signs of wear or damage.

Question 15

14)Which of the following statements is LEAST-Likely true?

A) Commercial rebuilders decide whether to replace a bearing by spinning it while "listening" with a special device that can tell if it makes too much noise.
B) If a bearing is tight or feels rough, replace it.
C) Most starters use bushings because the armature rotates for long periods like an alternator.
D) Inspect bearings visually and by feeling them for roughness.

Question 16

3)When battery voltage drops, amperage decreases, cranking rpm is lower, and ignition voltage drops.

Question 17

5)When there is less than 0.6 volt of total voltage drop in the starting circuit, service work is required.

Question 18

15)All of the following statements are true EXCEPT:

A) if the starter drive will be reused, you should immerse it in cleaning solvent.
B) whenever a starter is apart, new brushes should be installed.
C) some starter brushes are soldered in place, and others can be installed with screws.
D) starter brushes occasionally wear too thin and have to be replaced.

Question 19

13)Which of the following statements is LEAST-Likely true?

A) Later-model cars with manual shift transmissions have a clutch start switch.
B) Continuity when the clutch is depressed allows current to flow through the switch to the starter.
C) A starter drive can be bench tested to see if it will slip.
D) Many shops replace solenoids with starter drives.

Question 20

10)____ is an excellent way to check for resistance in a circuit.

A) Lead oxidization
B) Voltage drop testing
C) Work harden
D) Furnace brazing
