Question 1
2. An air bag system is being serviced. Tech A says to disconnect the yellow SRS connectors
at the front of the vehicle. Tech B says to disconnect and isolate the negative battery cable.
Who is right?
A. Tech A only
B. Tech B only
C. Both A and B
D. Neither A or B
CORRECT ANSWER
B- Always disconnect the ne the negative battery cable and wrap with tape so contract
cannot be made. Follow the specific vehicle's disarming instructions, as some SRS system
can retain back up power for an additional period of time.
Question 2
3. Which of these should be used when soldering electrical wiring connections?
A. Rosin Core Flux
B. Acid core Flux
C. Sulfur Core Flux
D. none of the above.
CORRECT ANSWER
A- for best results and less corrosion at the solder point, a rosin core flux should be used.

,Question 3
4. When testing computer controlled systems, a digital multi-meter should be used with an
input impedance of at least:
A. 10k ohms
B. 100k ohms
C. 1 megohm
D.10 megohms
CORRECT ANSWER
D- For maximum protection to the computer controlled system of any electronic circuit, it
is best to use at least a 10 megohm impedance digital multimeter.
Question 4
5. When troubleshooting a slow drain on the battery, which of these diagnostic tools
should be used?
A. Ohmeter
B. ammeter
C. voltmeter
D. Test light
CORRECT ANSWER
B- always use an ammeter of a low amperage amp clamp with your DMM to troubleshoot
a slow drain in an electrical circuit>
Question 5
6. The condition of a lead-acid battery is being checked. Tech A says to use a
galvanometer.. Tech B says to use a capacitive battery tester.
A. Tech A only
B. Tech B only

, C. Both A and B
D. Neither A or B
CORRECT ANSWER
B- A galvanometer is an analog type voltmeter. OEMs almost universally recommend the
use of a non intrusive conductive capacitive type battery tester.
Question 6
7. While testing a starting circuit on a 5.7 V8 engine, the Tech finds that the engine cranks
slowly. The starter current draw is 90 amps, and the battery voltage while cranking is 11
volts. What should the Tech Do next?
A. Check for voltage drop of the starter motor circuit.
B. Test the battery capacity.
C. Replace the starter motor, as a short is indicated.
D. Determine the condition of the engine.
CORRECT ANSWER
A- if an engine cranks slowly and the starter current draw is only 90 amps and the voltage
is as high as 11 volts, the tech should next check for excessive voltage drop in the starter
motor circuit.

8. Tech A says that a noisy alternator could be caused by a bad diode. Tech B says that
noisy alternator could be caused by a worn bearing. Who is right?
A. Tech A only
B. Tech B only
