ASE A6 Test Prep (Electrical & Electronic Systems)
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" terminal of 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.

2. Replace the bat- When performing a load test on a battery, a technician finds that the battery
tery 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 says to remove the surface charge from a recently charged battery
and apply a 300-ampere load across the adapters for 15 seconds.
Technician B says to remove the surface charge from batteries, which have been
in storage.

4. Technician B only Technician A says proper starter operation depends on the battery 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
the drop 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.

drive engaged?
a. Defective starter drive
b. Defective solenoid
c. Open pull-in winding
d. Worn armature commutator
6. Neither Techni- Two bulbs are connected in parallel to a 12 volt battery. Another bulb is added in
cian A nor B 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 decrease
due to the extra load.

7. Technician B only Two bulbs are connected in parallel to a 12 volt battery. One bulb has a resistance
of 6 ohms and the other has a resistance of 2 ohms.
Technician A says that only the 2 ohm bulb will light because all the current will
flow through the 6 ohms bulb.
Technician B says that the 6 ohm bulb will be dimmer than the 2 ohm bulb.

a. They are less expensive than conventional wire
b. They are more flexible to allow movement of the engine without breaking the

c. They dampen Radio-Frequency Interference (RFI)
d. Both B & C
10. Both Technicians Technician A says that a test light should light on both test points of the fuse if it
