1. When using a DMM (Digital Multimeter) voltmeter function to check for a voltage
drop, meter leads should be connected in which of the following ways?
a. On the "positive" side of the circuit
b. Across the component or circuit
c. To any non-conductive material
d. In series with the circuit -CORRECT ANSWER b. Across the component or circuit
Voltage is always checked in parallel or across the device or circuit.
2. Which of the following is correct regarding a series circuit?
a. Highest resistance has most current
b. Lowest resistance has most current
c. Lowest resistance has highest voltage drop
d. Highest resistance has highest voltage drop -CORRECT ANSWER d. Highest
resistance has highest voltage drop
Based on Kirchhoff's Voltage Law: Voltage higher before resistance than after, which is
the result of total applied voltage not equal at both ends of a single load circuit.
Resistance in circuit opposes electron flow with resulting voltage loss applied to load.
The Loss is voltage drop with the voltage lost/consumed as current moves through
resistance. HIGHER Resistance, HIGHER DROP.
3. When a Digital Multimeter (DMM) is used to measure DC voltage and is connected in
parallel to the load device, which of the following defines the reading?
a. Amperage reading
b. Voltage drop
c. Voltage spike
d. Pulse width modulation -CORRECT ANSWER b. Voltage drop
Based on Kirchhoff's Voltage Law: Sum of voltage drops in any circuit will equal source
VOLTAGE or VOLTAGE applied to circuit.
4. Which of the following tools can be used to check the continuity of wires that carry
digital signals?
a. Megger Meter
, b. Analog meter
c. Logic probe
d. Voltmeter -CORRECT ANSWER c. Logic probe
A logic probe is the only device that measures digital signals.
5. Using a DMM (Digital Multimeter), a fully charged 12 volt battery should indicate how
much voltage on the open circuit voltage (OCV) test?
a. 9.6 volts
b. 4 volts per cell
c. 1 volt per cell
d. 12.6 volts -CORRECT ANSWER d. 12.6 volts
The standard is 2.1 volts per cell and 2.1 times 6 is 12.6 volts.
6. Two technicians are discussing a battery's state of charge. Technician A says a
specific gravity of 1.225 at 80F indicates that a battery's state of charge is approximately
75%. Technician B says you can use a hydrometer to check battery state of charge on a
maintenance free battery. Who is right?
a. A only
b. B only
c. Both A and B
d. Neither A nor B -CORRECT ANSWER a. A only
Technician A is correct and Technician B is wrong because maintenance free batteries
do not have openings to check the specific gravity of the electrolyte with a hydrometer.
7. 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 action to perform?
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 -CORRECT ANSWER c. Replace the battery
The battery was tested under load and failed.
8. Two technicians are discussing testing a battery using an electronic conductance or
continuity tester. Technician A says some of these testers can load test a battery.
Technician B says you need to make sure that the ignition switch and all accessories
are off. Who is right?
a. A only
b. B only
