| RR 238 (150 BKS.) (DB {Donald Bastow - Suspensions} 461-8-12-24) MP 306975 ROLLS-ROYCE LTD. INSTRUCTIONS. To: E.F.C. Order No.: AD35 Customer's No.: X7730 23 Ex Switchbox Connections The magneto wires on the switchbox were found to be interchanged although in the auxiliary magneto switch they were correct. The result was that the magneto could be left on with the switchbox in the "Off" position and in the two middle positions the magneto was off. The connections have now been corrected and the magneto switching operates as intended, although it is possible to receive a shock from the auxiliary switch when in the 'off' (closed) position if the switchbox is in the "M&C" position. This is in accordance with anticipation. Signed: H.A. This Sheet must be filed on completion of the work. | ||
