| X4338 To EP. {G. Eric Platford - Chief Quality Engineer} from EFC. {E. Fowler Clarke - Electrical Engineer} c. By. {R.W. Bailey - Chief Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 4/T20.7.23. X.4338 - 20 H.P. ELECTRICAL SYSTEM. & Answering your EP {G. Eric Platford - Chief Quality Engineer} 3/H19.7.23, the matter is still under consideration, see our EFC {E. Fowler Clarke - Electrical Engineer} 3/T20.7.23 to BJ.. For the time being there seems no reason why we should not circularise all our Depots, Agents, Visiting Inspectors, Final testers, Coachbuilders and other people who handle cars, to the effect that if it is desired to run a magneto fitted car with the battery removed, the dynamo wires should first be disconnected.
