| X.4075. To E.{Mr Elliott - Chief Engineer} from EFC. c. Ey. c. EP.{G. Eric Platford - Chief Quality Engineer} EFC1/T28.1.22. X.4075 - GOSHAWK WIRING. The Goshawk starter motor will take at least as large a current, if not larger, than the 40/50. The reason of this is that the motor is designed to take more current and do more work proportionally. My recommendation is that the starter cable be not reduced below 84/25's as suggested, which size we know to be too small, though standard for the 40/50. My recommendation in the 40/50 case was that we should use 84/24's. EFC. [Watermark: ORIGINAL LION BOND] [Watermark: 1804] [Watermark: MADE AT CROXLEY] | ||
