ASE A6 practice test questions and answers 100% pass 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. - Answer ️️ -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 - Answer ️️ -Always disconnect negative battery terminal A- for best results and less corrosion at the solder point, a rosin core flux should be used. - Answer ️️ -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. 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. - Answer ️️ -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 B- always use an ammeter of a low amperage amp clamp with your DMM to troubleshoot a slow drain in an electrical circuit - Answer ️️ -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- A galvanometer is an analog type voltmeter. OEMs almost universally recommend the use of a non intrusive conductive capacitive type battery tester. - Answer ️️ -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 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. - Answer ️️ -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. C- Both techs are correct, worn alternator bearings and/or a bad alternator diode will cause the alternator to be noisy. - Answer ️️ -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 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. - Answer ️️ -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 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 - Answer ️️ -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. A short to ground has little or no resistance. Current flow increases as resistance decreases. - Answer ️️ -11. 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 A- A voltmeter should first be used to see if the circuit is getting power before doing further tests. - Answer ️️ -13. 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 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. - Answer ️️ -14. 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. D- neither tech is right. A poor headlight ground would cause both the high and low beam lights to be dim. A shorted headlight switch would only cause the headlights to operate incorrectly or not at all. - Answer ️️ -15. 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 B. Tech B only C. Both A and B D. neither A or B A- since voltage is supplied to the indicator light when the ignition switch is on, the indicator light will normally light when the oil pressure switch supplies a ground to complete the circuit. if a short to ground occurs between the indicator light and the oil pressure switch, the light will be on whenever the ignition switch is in the ON position. An open switch prevent the light from coming on. - Answer ️️ -16. The oil pressure light on a vehicle dashboard stays on whenever the engine is running. The oil pressure has been checked with a mechanical gauge and it is within specs. Tech A says that the circuit between the indicator light and the pressure switch could be grounded. Tech B says that an open in the
