| To R.{Sir Henry Royce} from EFC. c. BJ. EY. Hs.{Lord Ernest Hives - Chair} X7610 EFC2/T15.6.26. RE SEQUENCE SILENT STARTER. Answering your R16/M10.6.26, the progress which has been made in this direction subsequent to our EFC2/T18.11.25 of the operation of the apparatus on 9-EX, was consisted in the complete re-instructioning of the job from W.W. to the Drawing Office and from the Drawing Office to our Expl. shop. The alterations in the main comprise - (1) Completely redesigned actuator box with switch operated by movement of motor pinion. (2) Alteration in the reduction ratio of epicyclic gear. (3) Minor alterations to winding and gaps of the main and relay double switch unit. (4) The Duplex push button starter switch. As regards (3). Of the two main and relay switch units which have already been produced, one on chassis 9-EX forming part of the previous equipment, has been re-arranged as regards gaps and windings in order purely to overcome certain defects which we previously reported, and has overcome these satisfactorily, so that the system on that car is working satisfactorily with the exception of the thump on engagement and the following-up thump when the engine does not start.
