QUESTIONS AND CORRECT ANSWERS WITH RATIONALES
(VERIFIED ANSWERS) |AGRADE
- 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 – ANSWER- B- A galvanometer is an analog type voltmeter.
OEMs almost universally recommend the use of a non intrusive conductive
capacitive type battery tester. - 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. – 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. - 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 – ANSWER- C- Both techs are correct, worn alternator bearings
and/or a bad alternator diode will cause the alternator to be noisy. - 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 – ANSWER- 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. - 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? - 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 – 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.
7.Always disconnect negative battery terminal – ANSWER8. 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. – ANSWER- A- for best results and less corrosion at the
solder point, a rosin core flux should be used. - 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 – 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. - 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 – ANSWER- B- always use an ammeter of a low amperage amp
clamp with your DMM to troubleshoot a slow drain in an electrical circuit>
A. Tech A only
B. Tech B only
C. Both A and B
D. Neither A or B – ANSWER- 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
- Tech A says a short circuit to ground in a circuit will decrease resistance. Tech
B says a short circuit will increase current flow. Who is right?
A. Tech A only
B. tech B only
C. Both A and B
D. Neither A or B – ANSWER- C- Both techs are right. A short to ground has little
or no resistance. Current flow increases as resistance decreases. - When using a voltmeter to check for voltage in a circuit, the voltmeter should
first be connected to check for:
A. Source voltage.
B. excessive resistance
C. excessive amperage.
D. Good ground – ANSWER- A- A voltmeter should first be used to see if the
circuit is getting power before doing further tests. - When checking the green eye of a sealed maintenance free battery, no color
seen indicates that the battery is:
A. undercharged
B. charged properly.
C. Overcharged.
D. Damaged. – ANSWER- A- if the so called Green eye is not visible, the green tip
of the built in hydrometer is not floating high enough in the electrolyte to be
visible. A fully charged battery will cause the built in hydrometer to float to the top
of the electrolyte and allow the green tip of it to be seen. - Both headlights on a vehicle are dim on high beam but are normal on low
beam. Tech A says that a poor headlight ground could be the cause Tech B says
that a shorted headlight switch could be the cause. Who is right?
A. Tech A only
