| ROLLS-ROYCE LTD. INSTRUCTIONS. To: E7.6 Order No. WA {Mr Wallis} 109 Customer's No. X 3714 Static Induction effects with E.A.C H.T. wiring in black fibre insulating tube. Tests have now been carried out in connection with the above phenomenon, with the magneto and battery ignition wires bunched together in an insulated tube. as used on the E.A.C engine 5 tests in all were completed Firstly with one of the ignition generators switched off and the other working to observe the induced effect on the idle wires and Secondly - vice versa. The H.T sparking was then observed with both ignitions working together, and lastly Signed: contd This Sheet must be filed on completion of the work. | ||
