Frustration with print quality in the Rover Workshop Manual led to scanning the best single page image I could find, cleaning up all the features including connections, legends, wiring colour codes, etc. Haynes Manual has a clearer image but is split across 2 pages and has some errors. It also has an accompanying list of components and, not found elsewhere, all the Pick-Up Point Connection Codes presented in a single listing. So what the document contains is:

Page 1. Component Identification Numbers, Component Descriptions and Grid References.

Page 2. Pick-Up Point Connection Codes and Wiring Colour Code Key.

Page 3. High Quality Main Circuit Diagram Image. Temporary Image of Efi Circuit HERE (74kb)

It does not feature any of the supplimentary circuits such as Trip Computer, Electric Sunroof, etc, as all those diagrams are quite clear in the Workshop Manual.

Because the main circuits for other Series II cars are similar it might also help those owners who find their circuit diagrams have equally poor print quality. Print and laminate it for workshop use.

For hard copy, depending upon the printer used, the PDF will generate a good quality print and, if required, using Adobe Reader or MS Internet Explorer, the image can be rotated or enlarged to a significant level of clarity. It is also be possible to print an enlarged image given suitable software.
