ABSTRACT

The word ‘diagnostics' centres around the principle of the four rights: measuring the right thing, in the right way, at the right time, with the right tool. This book includes a basic explanation of the vehicle systems followed by diagnostic techniques that are particularly appropriate for that area. Examples of faultfinding charts are also included. An important note about diagnostics is that the general principles and techniques can be applied to any system, physical or otherwise. This chapter lists some particular risks when working with vehicle systems, together with suggestions for reducing them, as well as covers some particular risks when working with electricity or electrical systems, together with suggestions for reducing them. It also describes the main headings that a report will often need to contain together with an example report based on the performance testing of a vehicle alternator.
