Electrical Module 2 (Schematic Based Testing)
This hands-on program covers techniques for analyzing wiring schematics so that a technician can apply this information from the schematic to the vehicle electrical circuit. The instructor integrates Ohm's Law into common sense problem analysis. The program begins
with an explanation of how traditional wiring schematics were used and then evolves into how to use newer style 'simplified' wiring schematics.
Schematic examples from the classroom manual are used to explain how a problem can be caused by several different electrical faults. The technician uses the classroom simulator to practice troubleshooting techniques that will help find the cause without unnecessary parts replacement.
The lessons learned in this program can act as vital links in a technician's ability to analyze electrical faults.
Learning Objectives
All students will receive the following information:
- How to READ and USE an electrical schematic to rapidly diagnose complex electrical circuits
- How to use the Current Path electrical testing concept
- How to recognize important differences between early style and newer style simplified schematics
- How to read and interpret how a circuit should operate and function
- How to quickly determine if an electrical problem is related to the PCM power, ground or input circuit
Prerequisites
Students should have some previous training and experience in automotive electrical/electronics theory and application. They should also have some hands-on experience working with their own DVOM.
Target Audience
Automotive repair technicians, service mangers and writers, fleet managers and instructors.
