COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1. Demonstrate the proper use of a Digital Multimeter (DMM) during diagnosis of electrical circuit problems, including: source voltage, voltage drop, current flow, and resistance.

2. Analyze and diagnose a mobile equipment charging system using appropriate electrical tools and equipment.

3. Analyze and diagnose a mobile equipment starting system using appropriate electrical tools and equipment.

4. Analyze and diagnose a mobile equipment low-voltage battery system using appropriate electrical tools and equipment.

 

Objectives:

At the conclusion of this 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, Watts Theory).

3. Demonstrate the proper use of a digital multimeter (DMM), test lights, logic probes, 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.

Methods of Evaluation/Basis of Grade.

Writing: Assessment tools that demonstrate writing skill and/or require students to select, organize and explain ideas in writing.		Writing 0 - 10%
Lab notebook
This is a degree applicable course but assessment tools based on writing are not included because problem solving assessments and skill demonstrations are more appropriate for this course.
Problem solving: Assessment tools, other than exams, that demonstrate competence in computational or non-computational problem solving skills.		Problem Solving 5 - 20%
Lab reports
Skill Demonstrations: All skill-based and physical demonstrations used for assessment purposes including skill performance exams.		Skill Demonstrations 30 - 50%
Lab exercises and skills test
Exams: All forms of formal testing, other than skill performance exams.		Exams 30 - 50%
Weekly quizzes; midterm exam; final exam
Other: Includes any assessment tools that do not logically fit into the above categories.		Other Category 0 - 0%
None
