We could possibly make the wire of finer gauge so as to only take the same current, but we do not think this would be advisable from the point of view of the ballast resistance itself. Another point is that some difficulty has been experienced in starting up the 40/50 car on a cold morning, and as a result of this it has been suggested to me that the ballast resistance ought to be reduced in magnitude. We will take up the matter with Messrs. Lucas as to whether they cannot make their curve of Goshawk dynamo output keep up a bit more than at present in the later stages, as is the case with the C.A.V. EFC. | ||
