| RR 238 (150 BKS.) (DB{Donald Bastow - Suspensions} 481-8-12-24) MP 306975 ROLLS-ROYCE LTD. INSTRUCTIONS. (2) To _________ 19__ Order No. _________ Customer's No. _________ We suggest that the fault on the ignition system of the car in question was probably due to something else as the coil appears OK, but we think this coil ought to be tested on an engine to finally confirm this. Further to the above we have heated the coil in an oven up to 100°C and maintained it at that temp for 30 mins without failure although as would be expected misfiring occurred on 8V. Signed H.E.W. This Sheet must be filed on completion of the work. | ||
