| X6016 Extract from PN{Mr Northey}'s note in X.8780 ref. PN{Mr Northey}20/GM19.12.30. X8780 X5780 X3374 Am I right in assuming that the switching proposition you have proposed in the latter memo will enable the generator to cut-in at 15 or 16 mp.h. if desired? --- Extract from our note in reply ref. EFC5/AD23.12.30. The switching proposition proposed in our EPCL/AD12.12.30 does not affect the cutting in point of the dynamo except insofar as this is enabled to give full output and therefore earlier cutting in when the head lamps are not "on". | ||
