Wiring Diagrams
Purpose
Wiring diagrams are an aid to trace wiring faults. Wiring Diagrams are used to complement the
fault analysis information contained in the relevant RAP.
NOTE: If necessary, refer to GP 20 for the acronym list and cross reference lists of more com-
monly recognised part names.

The wiring diagrams have the following features:
• The connections on the PWBs are in numerical sequence where possible.
• The complete component to PWB wiring is shown. All interconnecting connectors shown,
in part or whole. Connectors shown in part have reference to other wiring diagrams as
necessary.
• Where necessary, components have references to show additional connections to them.
• Relevant parts list references are shown.
