X 3460 X 3428 X.2641 - X.3034 In answer to your EP{G. Eric Platford - Chief Quality Engineer}14/F28.11.19, we were under the impression that, except for a few failures quite early on, the action of the electrical operating mechanism for the starter motor was quite satisfactory. We do not recall to mind any complaints except those which occurred in the early days before we had pointed out and had remedied certain defects in the actuator box. We can appreciate, however, that the phenomenon you mention in the second paragraph can quite possibly take place, and would like to see this ourself actually occurring. We are, as you probably know, experimentally arranging the main switch and actuator box with suitable coils to be run in series and we have proportioned these new coils so that the ampere turns of the actuator box are relatively stronger in comparison with the main switch than is at present the case. This alteration, however, will presumably have to pass through the 10,000 mile test before being standardised. We are instituting experiments on the combination of push button switch, main switch and actuator box, both for the present parallel wiring and for the experimental series winding, in order to compare the working as regards the particular point which you raise of the main switch being | ||
