| X6057. Hd.{Mr Hayward/Mr Huddy} from EFC. EFCl/AD25.2.31. X.6117. BATTERY IGNITION TUNGSTEN CONTACT POINTS. With reference to the attached letter, in view of the fact that the contacts are making good contact and are not pitted, it is difficult to give a suggestion to eliminate the fault. We suggest that the next time it occurs another new pair of contacts be fitted and the old pair be returned to us for examination exactly as removed. EFC. Letter attached. | ||
