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. Who is right?

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

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.
