| X4081 Extract from E4/G31.3.21. RE VISIT OF MESSRS. HIVES & DAY TO W.W. ON 6-EX. MARCH 12TH 1921. (14) "GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) II" ELECTRICAL SYSTEM. X.4338. X.3915. X.4081. For operating the starter motor Mr. Royce wishes to use the central pedal carried on the dash mechanically connected to a switch on the motor itself. There should be a distribution board for the electrical system, but only one switch box. The cutout should be put on the dynamo to save wiring, and for the lights a controller or barrel type of switch should be used because it is easy to lock this in any one position. Use also the same form of switch for the ignition. | ||
