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 ✔✔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.
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. ✔✔A- for best results and less corrosion at the solder point, a rosin core
flux should be used.
,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 ✔✔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.
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 ✔✔B- always use an ammeter of a low amperage amp clamp with your DMM to
troubleshoot a slow drain in an electrical circuit>
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 ✔✔B- A galvanometer is an analog type voltmeter. OEMs almost universally
recommend the use of a non intrusive conductive capacitive type battery tester.
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. ✔✔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
, C. Both A and B
D. Neither A or B ✔✔C- Both techs are correct, worn alternator bearings and/or a bad alternator
diode will cause the alternator to be noisy.
9. The analog ohmmeter needle does not move when connected to both sides of the rotor. This
means the rotor winding is?
A. Shorted
B. Grounded
C. Complete
D. Open ✔✔D- if the circuit is open, as in the rotor winding shown, the Ohmmeter will show
infinite resistance or infinity, and the needle will not move.
10. A vehicle's turn signals flash too slowly. tech A claims that the condition could be caused by
a faulty flasher. Tech B says that a bulb may be the wrong type. Who is right?
A. Tech A only
B. Tech B only
C. Both A and B
D. Neither A or B ✔✔C- Both techs are right. Both an improperly rated flasher and an incorrect
wattage bulb can cause the turn signals to flash at incorrect intervals
