| EFC3/T18.8.27. Extract X8673 Contd. Speaking of the 40/50 dynamo, now that we have standardised the N.B. (narrower brush and larger air gap) machine, a corresponding series of brush tests, i.e. with similar grades is in progress, as time and opportunity permit. All of the above tests were as nearly as possible in the same electrical condition (other than the brushes) and were run on the highest volt-ampere output characteristic likely to be met with on chassis. Also under similar temperature conditions. EFC. | ||
