| To BJ. from Hs.{Lord Ernest Hives - Chair} c. to CWB. H5660 Hs{Lord Ernest Hives - Chair}4/LG14.9.25. 9-G-111 - DYNAMO. x4610 (5660) With reference to BJ2/H14.9.25. During the experimental tests on 9-G-111, there was considerable trouble with the dynamo. The brushes had received attention. We know from experience with that particular dynamo, that the most probable cause of the failure was the control brush sticking. Until we get the dynamo back and examine it, it is must impossible to locate the cause of it failing. The dynamo on 9-G-111 is no different to that fitted to the present standard 20 HP. cars.
