ASE A6 (ELECTRICAL & ELECTRONICSYSTEMS) EXAM 2024/2025
Technician A only - Precise Answer ✔✔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.

,Replace the battery - Precise Answer ✔✔When 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 - Precise Answer ✔✔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.

Technician B only - Precise Answer ✔✔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.

Defective starter drive - Precise Answer ✔✔Which 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 - Precise Answer ✔✔Two 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.
