| To RHC.{R. H. Coverley - Production Engineer} from EFC. X8650 EFC1/T7.11.24. X.8650. RE SILENT STARTER GEAR. EAC.II. To improve the reliability of operation of the silent starter gear, as fitted upe on 98-NK, it will be necessary to reduce by 1/3 the bye-pass resistance which we have located in the base of the combined main and relay switch unit. At present a start is uncertain, the motor not always turning. Will you kindly have this seen to at the earliest possible moment. EFC. | ||
