In the case of poor compression on one cylinder, given above as an example, the analysis would take the form of tests to determine the cause of low compression,e.g. burnt valve, blown head gasket etc. The analysis of evidence that is performed will vary according to the system under investigation. But these steps are obviously important otherwise one may embark on a drawn out electronics test procedure which will prove unproductive.

The procedure for doing this on an electronics system varies according to the type of test equipment available. It may be the case that the system has  some self-diagnostics which will lead you to the area of the system which is defective. Let us assume that this is the case and the self-diagnostics report that an engine coolant temperature sensor is defective. How do you know whether it is the sensor, or the wiring between it and the remainder of the system? Again this is where a good basic knowledge of the make-up of the system is invaluable.
