ASE A6 practice test questions and answers 100% pass 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 u p 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. 100 k 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 the se 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 bei ng 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 alterna tor 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 r esistance 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
