| X3445 To HY.{Tom Haldenby - Plant Engineer} from EFC. c. EP.{G. Eric Platford - Chief Quality Engineer} EFC1/T15.4.24. X.3445 - IGNITION COIL EX CHASSIS 58-S7. IGNITION COIL EX CHASSIS 44-G7. It has transpired that we were in error in putting down the faults on the above two coils, reported in our EFC1/T2.4.24 and EFC6/T4.4.24, respectively, as faults of the secondary winding. It now appears that the symptoms, which symptoms were correctly recorded, should have been ascribed to the known fault in these coils of a partial failure of the insulation of the primary winding.
