Course Outline for Automotive Technology 60B

AUTOMOTIVE ELECTRICS/ELECTRONICS II

Catalog Description:

60B - Automotive Electrics/Electronics II 3.5 units

(May be repeated three times)

Continuation of Automotive Technology 60A with emphasis on diagnosis and repair of electrical/electronic components including computer controlled circuits/systems using schematics, diagnostic procedures and equipment; headlamp adjusting and repair. May not receive credit if Automotive Technology 71 has been completed. Prerequisite: Automotive Technology 60A or equivalent. 2 hours lecture, 5 hours laboratory.

[Typical contact hours: lecture 35, laboratory 87.5]

Prerequisite Skills:

Before entering the course the student should be able to:

1.  Identify and interpret electrical/electronic system concern, and determine necessary action;

2.  Diagnose electrical/electronic integrity for series, parallel and series-parallel circuits using principles of electricity (Ohm’s Law);

3.  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;
