INTRODUCTION


This Group consists of five major diagnostic sections for electrical problem troubleshooting.


- Schematic diagrams

- Component location indexes

- Harness layouts

- Component location

- Connector configurations


The starting point of each system section is the schematic diagram, these diagrams show how all the components work together, such as electrical current paths from power source to ground (via electrical load), switch connections at each positions, and other related circuit functions.

It is important to fully understand how a circuit works prior to troubleshooting and diagnosis.
