| BY.{R.W. Bailey - Chief Engineer} FROM E.{Mr Elliott - Chief Engineer} 2 ORIGINAL E2/M29.6.28. C. to BJ. HS.{Lord Ernest Hives - Chair} EFC. PHANTOM TECHNICAL WIRING DIAGRAM. X.7560. X4040 We send herewith LeC. 2570. shewing a revision to the above. The diagram has been re-arranged to segregate the various circuits, and these circuits have also been coloured to correspond with the actual conductors used. All this renders the diagram very much more easy to understand, and very much more useful in tracing faults. The green lamp indicator is also included. Mr. Royce would like you to have this new diagram incorporated in the instruction book. E.{Mr Elliott - Chief Engineer} | ||
