R.R. 199 (250T) (SD676 10-7-17) MP18/866 E7C from Dy{F R Danby} X. 30146 26/7/20 Mr Ireland had arranged before coming over a scheme which took away the Electrical main. He rotated the brushes a certain amount. Brach had previously tried this but as when he tried it the B output fell to 12 amps he did not go further. The dynamo as above cuts in earlier & gives 12 Amp max & fall within new dynamo schedule. We are sorry on these lines. By | ||
