| 6614 To By {R.W. Bailey - Chief Engineer} /RD. from Rm {William Robotham - Chief Engineer} /RC. {R. Childs} Rm {William Robotham - Chief Engineer} /RC. {R. Childs} 11/MH. {M. Huckerby} 23.5.39. RE CHANGEOVER SWITCH FOR BENTLEY. In accordance with memo By {R.W. Bailey - Chief Engineer} /RD.3/B.22.3.39 two ignition coils were connected as suggested with the exception that an HT. switch was not inserted in the circuit; the HT. lead from coil to distributor being placed into each coil in turn to effect the change-over. No noticeable diminution of output was found in either case, and no other ill effects were to be found. We recommend, therefore, that a combined HT. and LT. switch be now obtained in order that the arrangement may be tried out on an experimental car. Rm {William Robotham - Chief Engineer} /RC. {R. Childs} | ||
