| C O P Y. ----- TO BY.{R.W. Bailey - Chief Engineer} FROM E.{Mr Elliott - Chief Engineer} S E C R E T. E1/M8.7.24. ---------------- ------------------- E.{Mr Elliott - Chief Engineer} A.{Mr Adams} C. 11. In reply to your memo BY16/H4724. the following is the condition of the points you mention. (1). AUTOVAC CONNECTION TO THE INLET PIPE. We will let you have a scheme for this. (2). RADIATOR SHUTTER CONTROL. DA.{Bernard Day - Chassis Design} is writing to you about this. (3). UNDERSHIELD. We have schemes nearly completed for EAC.2. undershields, which we hope to send you very shortly. (4). ELECTRICAL SECTION. With regard to the switchbox it is quite true that at one time the condition was as stated by DA.{Bernard Day - Chassis Design} but since then Mr. Royce sent you a memo. - R3/M4624. which represents the latest instruction, and in which he asks you to slightly modify the 4 position switchbox to provide the order of switching stated in the memo, and to fit an extra small switch for earthing the magneto in parallel with the box. This switch might be a small tumbler switch on the back of the instrument board, such as we have on 6.EX. With regard to the push button starting switch on the instrument board I am taking this matter up with Mr. Royce. With regard to the use of the insulated terminal post on the battery ignition tower, this is intended for use in the event of the battery ignition being out of order, to enable the driver to use the switchbox without causing damage by switching on the battery ignition current. It obviates the necessity of removing the battery ignition fuse under the same conditions. E.{Mr Elliott - Chief Engineer} | ||
