Demonstrate the proper use of a digital multimeter (DMM),test lights and fused jumper wires during diagnosis of electrical circuit problems; 4. Measure and diagnose the cause(s) of excessive key-off battery drain (parasitic draw); 5. Inspect and test fusible links, circuit breakers, and fuses, repair wiring harnesses and connectors, and perform solder repair of electrical wiring; 6. Perform battery state-of-charge test; capacity test, and confirm proper battery capacity for vehicle application; 7. Perform battery service, perform slow/fast battery charge, inspect and clean battery cables; connectors, clamps, and hold-downs, repair or replace as needed; 8. Start a vehicle using jumper cables and a battery or auxiliary power supply; 9. Perform starter current draw tests, generator (alternator) output tests, circuit voltage drop tests; 10. Inspect and test starter relays and solenoids; 11. Remove and install starters and alternators; 12. Inspect, adjust, or replace generator (alternator) drive belts, pulleys, and tensioners; check pulley and belt alignment; 13. Inspect and test ignition primary and secondary circuit wiring and components 14. Inspect, test and service distributor; 15. Inspect and test ignition coil(s). Check and adjust ignition system timing and timing advance/retard (where applicable). Expected Outcomes for Students: Upon completion of the course, the student should be able to: 1. Diagnose the cause of brighter than normal, intermittent, dim, or no light operation in lighting systems; 2. Inspect, replace, and aim headlights and bulbs; 3. Inspect and diagnose incorrect turn signal or hazard light operation; 4. Inspect and test gauges and gauge sending units for cause of intermittent, high, low, or no gauge readings; 5. Inspect and test sensors, connectors, and wires of electronic instrument circuits; 6. Diagnose incorrect wiper/washer operation, and perform necessary action; 7. Diagnose incorrect operation of motor-driven accessory circuits, and determine necessary action; Chabot College Course Outline for Automotive Technology 60B, Page 2 Fall 2005 8. 9. 10. 11. Diagnose supplemental restraint system (SRS) concerns; determine necessary action; Diagnose body electronic system circuits using a scan tool; Access and use service information to perform step-by-step diagnosis; Diagnose ignition system related problems such as no-starting, hard starting, engine misfire, poor driveability, spark knock, power loss on vehicles with electronic ignition systems, and determine necessary action; 12. Check and adjust ignition system timing and timing advance/retard (where applicable); 13. Inspect and test ignition system pick-up sensor or triggering devices, and perform necessary action.
