| X.1413 ToDa. from EFC. c. to De/Thr. EFC9/T31.12.20. X 1413 BATTERY IGNITION SWITCH TERMINALS. X 3129 Even when the ignition is switched off, one of the terminals of the insulated battery ignition switch at the bottom of the steering column is alive and the accidental connection between this terminal and the frame by means of a tool causes a spark which is sufficient to ignite petrol vapour if the carburetter has been flooded for some reason. Would you kindly look into the possibility of providing the live terminal with an insulating thimble to avoid the possibility of this occurrance. EFC. R.R. 286A (100) T1 (S.H.) 19.11.20 C. 7850 | ||
