Introduction To Diagnosis Charts

No matter what form charts may take, they are simply a way of expressing the relationship between basic logic and a physical system of components. It is a way of determining the cause of a condition in the shortest possible amount of time. Diagnosis charts combine many areas of diagnosis into one visual display:
^ Probability of certain things occurring in a system.
^ Speed of checking certain components, or functions, before others.
^ Simplicity of performing certain tests before others.
^ Elimination of checking huge portions of a system by performing simple tests.
^ Certainty of narrowing down the search to a small portion before performing in-depth testing.
The fastest way to find a condition is to work with the tools that are available, which means working with proven diagnosis charts and the proper special tools for the system being worked on.
