ASE A6 Test Prep (Electrical &
Electronic Systems)
Technician A only - answerA 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.

Replace the battery - answerWhen performing a load test on a battery, a technician
finds that 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
Technician A only - answerTwo 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.

Technician B only - answerTechnician 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.

Defective starter drive - answerWhich of the following could cause the starter to make a
whining noise when engaged?
a. Defective starter drive
b. Defective solenoid
c. Open pull-in winding
d. Worn armature commutator
Neither Technician A nor B - answerTwo bulbs are connected in parallel to a 12 volt
battery. 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 decrease due
to the extra load.

Technician B only - answerTwo 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.

Both B & C - answerMany 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
Both Technicians A and B - answerTechnician A says that a test light should light on
both 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 of the
fuse.
