Using the Sub-System Wiring Diagram

An example of two spreads for a sub-system - in this case the interior lighting with time delay - is shown below, together with explanations of the designations used, etc.

Unless otherwise specified, switches are shown in un-actuated condition and relays in de-energized condition.




In the sub-system diagrams, every subsystem is generally shown from the relevant fuse in the electrical distribution box, up to each consumer or sub-system, and then to the earthing point (chassis connection).

The supply to each fuse is shown separately in the section entitled "Positive supply", which also deals with the electrical distribution box, ignition switch, etc.

If +30, for instance, is written above a fuse, the supply from the battery to the respective fuse is shown in the section entitled "Positive supply +30".




Most of the earthing points in the car have a component number, and the various earthing points in each diagram are marked with the appropriate number. The locations of the earthing points with component numbers are specified in the section entitled "Earth connections".
