ASE T6 Domain 1: General Electrical/ Electronic System Diagnosis Welcome to your ASE T6 Domain 1: General Electrical/ Electronic System Diagnosis 1. ASE T6: General Electrical/ Electronic System Diagnosis When diagnosing an intermittent electrical fault in a heavy-duty truck, what diagnostic tool is MOST effective? A. Circuit tester B. Digital multimeter set to measure voltage C. Oscilloscope D. Test light None 2. ASE T6: General Electrical/ Electronic System Diagnosis A truck exhibits erratic behavior of electronic systems while driving. The FIRST component to inspect should be the: A. ECM (Engine Control Module) B. Battery connections C. Ground connections D. Alternator None 3. ASE T6: General Electrical/ Electronic System Diagnosis When diagnosing a circuit with excessive voltage drop, the MOST likely cause is: A. A short to ground B. Corroded connections C. A blown fuse D. An open circuit None 4. ASE T6: General Electrical/ Electronic System Diagnosis In a heavy-duty truck, flickering headlights at idle could indicate a problem with the: A. Headlight switch B. Alternator diodes C. Battery terminals D. Headlight relay None 5. ASE T6: General Electrical/ Electronic System Diagnosis A technician is diagnosing an electrical issue and finds a fuse that repeatedly blows. The MOST likely cause is: A. A short to power in the circuit B. An overcharged battery C. A high resistance connection D. An open circuit in the wiring None 6. ASE T6: General Electrical/ Electronic System Diagnosis A heavy-duty truck with an electronically controlled engine experiences intermittent stalling. The FIRST electronic component to check is the: A. ECM (Engine Control Module) B. Vehicle speed sensor C. Crankshaft position sensor D. Throttle position sensor None 7. ASE T6: General Electrical/ Electronic System Diagnosis When diagnosing a charging system fault, an alternator output test shows low amperage output. The technician should FIRST check: A. The alternator drive belt tension B. The battery state of charge C. The alternator voltage regulator D. The alternator brushes and slip rings None 8. ASE T6: General Electrical/ Electronic System Diagnosis In a truck, a voltmeter connected across the battery terminals shows a reading higher than the specified charging voltage. This is an indication of: A. A failing battery B. A defective voltage regulator C. Poor ground connections D. An underperforming alternator None 9. ASE T6: General Electrical/ Electronic System Diagnosis A heavy-duty truck's electrical system experiences intermittent power loss. A technician should FIRST check the: A. Battery fluid levels B. Main power relay C. Ignition switch contacts D. Wiring harness for chafing None 10. ASE T6: General Electrical/ Electronic System Diagnosis A technician finds that an electronically controlled diesel engine is not starting. The initial step should be to check the: A. Fuel supply system B. Electronic control module (ECM) power and ground C. Engine oil level D. Air filter restriction None 1 out of 10 Time is Up! Time's up
