1. Technician A only: A technician connects one lead of a DMM (digital multimeter)to the
positive (+) terminal of a battery and the other meter lead to the "B" terminalof the
starter solenoid and then cranks the engine. During cranking, the voltmeter displays a
reading of 878 mV.
Technician A says this reading indicates the positive battery cable has very high
resistance.
Technician B says this reading indicates that the starter armature is defective.Who is

Both Technicians A and B
Neither Technician A nor B
2. Replace the battery: When performing a load test on a battery, a technician findsthat
the battery voltage drops below specifications. Which of the following is the MOST likely
repair?
a. Recharge the battery and return it to service
b. Recharge the battery and retest it
c. Replace the battery
d. Replace the voltage regulator
3. Technician A only: Two technicians are describing battery charging.
Technician A saysto remove the surface charge froma recently charged battery andapply a
300-ampere load across the adapters for 15 seconds.
Technician B saysto remove the surface charge from batteries, which have been instorage.

4. Technician B only: Technician A says proper starter operation depends on thebattery
being at a 95% charge and battery cables being of the correct size (gauge)and having no
more than 0.8-volt drop.
Technician B says voltage-drop testing includes cranking the engine, measuring thedrop in
voltage from the battery to the starter, and measuring the drop in voltage from the
negative terminal of the battery to the engine block.

5. Defective starter drive: Which of the following could cause the starter to makea
whining noise when engaged?
a. Defective starter drive
b. Defective solenoid
c. Open pull-in winding
d. Worn armature commutator
6. Neither Technician A nor B: Two bulbs are connected in parallel to a 12 voltbattery.
Another bulb is added in parallel.
Technician A says that the third bulb will be dimmer than the other two bulbs due to
reduced current flow through the filament of the bulb.
Technician B says that the amount of current flowing from the battery will decreasedue to
the extra load.
Who is right?
Technician A only
Technician B only
Both Technicians A and B
Neither Technician A nor B
7. Technician B only: Two bulbs are connected in parallel to a 12 volt battery.Onebulb has
a resistance of 6 ohms and the other has a resistance of 2 ohms. Technician A saysthat
only the 2 ohm bulb will light because all the current will flowthrough the 6 ohms bulb.
Technician B says that the 6 ohm bulb will be dimmer than the 2 ohm bulb.Who
is right?

b. An increase in current through the circuit
c. A decrease in circuit resistance
d. Both B & C
9. Both B & C: Many ground straps are uninsulated and braided because
?
a. They are less expensive than conventional wire
b.They are more flexible to allow movement of the engine without breaking the wire
c. They dampen Radio-Frequency Interference (RFI)
d. Both B & C
10. Both Technicians A and B: Technician A says that a test light should light onboth test
points of the fuse if it is ok.
Technician B says that the fuse is defective if a test light only lights on one side ofthe
fuse.

11. Both B & C: Which statement is true about fuse ratings ?
a. The fuse rating should be less than the maximum current for the circuit.
b. The fuse rating should be higher than the normal current for the circuit.
c. 80% of the fuse rating should equal the current in the circuit.
d. Both B & C
12. The smaller the wire diameter: The higher the AWG #, ?
a. The thicker the insulation
b. The more strands in the conductor
