| X6004. To Mx.{John H Maddocks - Chief Proving Officer} from EFC. EFC4/ADL 3.2.31. X.6004. 48 COIL P.2. DYNAMO OUTPUT ON L.H. CHASSIS. May we please ask you to remember the Electrical Experimental Dept. when sending memos concerning the operation of the electrical system. It was necessary for us to obtain a copy of Mx{John H Maddocks - Chief Proving Officer}9/T10.2.31 from Ry's Dept. In regard to the drop of output after the machine has once left the production test we have, in our latest specification (i.e. for 48 coil medium output P.2. dynamos) made the necessary allowance for this. A report on the brush bedding problem generally is in preparation and you will receive a copy, this will deal with the details of the situation. We have not been in the habit of addressing copies of the production specification of inspection and test of electrical units to yourself when issuing these, though sometimes we have handed copies of these to Mr.Dakin or Mr.Archer. We could, if you thought it necessary or expedient, include you every time when issuing specifications. EFC. | ||
