ASE G1 Domain 6: Electrical Welcome to your ASE G1 Domain 6: Electrical 1. ASE G1: Electrical A vehicle's headlights dim when the RPMs drop at idle. The MOST likely cause of this is: A. A failing alternator B. A weak battery C. Corroded battery terminals D. Poor ground connection at the chassis None 2. ASE G1: Electrical A technician finds that the OBD II system is not communicating with the scan tool. The first thing to check should be: A. The vehicle's battery voltage B. The fuse for the OBD II system C. The data link connector (DLC) pins for damage D. The scan tool's software version None 3. ASE G1: Electrical A vehicle exhibits a slow engine crank and the battery is known to be good. Which of the following could be the cause? A. High resistance in the starter circuit B. A short in the starter motor windings C. An open in the charging circuit D. An overcharged battery None 4. ASE G1: Electrical When performing a voltage drop test on the ground side of a circuit, a reading of 0.4 volts is obtained. This indicates: A. The ground path is good B. There is high resistance in the ground path C. The test is inconclusive without a load test D. The voltage supply is inadequate None 5. ASE G1: Electrical A technician cannot get the engine to crank. After verifying the battery is fully charged and the starter is good, the next step should be to: A. Replace the ignition switch B. Test the neutral safety switch C. Check for an immobilizer system fault D. Inspect the starter relay None 6. ASE G1: Electrical A vehicle's electric cooling fan runs constantly, even when the engine is cold. What is the MOST likely cause? A. Faulty engine temperature sensor B. A shorted fan motor relay C. Defective fan control module D. Blown cooling fan fuse None 7. ASE G1: Electrical Which of the following is an indication of a charging system problem? A. The battery light is on with the engine running B. Headlights brighten as engine RPM increases C. Accessories operate slower as the engine idles D. The dome light dims slightly when starting the engine None 8. ASE G1: Electrical A vehicle's starter cranks excessively slow when the interior blower motor is turned on. This MOST likely indicates: A. A weak battery B. An overloaded starter motor C. Voltage drop in the charging circuit D. Excessive electrical accessory load None 9. ASE G1: Electrical A customer complains that their vehicle's starter intermittently does not engage. A technician should FIRST check: A. The ignition switch actuator pin B. The battery cable connections C. The starter solenoid contacts D. The automatic transmission range sensor None 10. ASE G1: Electrical During an inspection, a technician discovers that the alternator's B+ terminal is heavily corroded. This condition could result in: A. An overcharging battery B. A battery being undercharged C. An increase in alternator output D. A false battery temperature reading None 1 out of 10 Time is Up! Time's up
