| To BY {R.W. Bailey - Chief Engineer} /RD. from EFC. {E. Fowler Clarke - Electrical Engineer} X3485 EFC {E. Fowler Clarke - Electrical Engineer} 1/T23.9.25. X.3485 - BALLAST RESISTANCE COVER D.SCHEME .253. This has now completed 13,000 miles running, not showing any fault. Do you still consider there is any call for this fitment ? Have there been any more complaints of broken ballast resistances which this would overcome ? EFC. {E. Fowler Clarke - Electrical Engineer} | ||
