| - 2 - E.6/HP.26.7.33. There will be an ignition warning light incorporated in the 20/25 type of patch and the cutout will be on the positive instead of the negative side, similar to the arrangement we have adopted on Bentley. The arrangement of the instrument board will be as shewn on the attached sketch. It is understood that Hales are satisfied that the starter button position shewn is sufficiently accessible to the driver, but it is still possible to use a position lower down and nearer the driver which balances the starter carburetter recessing the button as is already done when the switch is low down, to avoid accidental operation by the passenger's knee. The following table gives particulars of the drawings for the vibrator control installation. BX/RD. will issue a complete list of L.O.P's for instructing Experimental Department. Scheme for Dashboard - Led.3584. Voltage regulator and field - resistance unit. - B.sch.621. Distribution Board. - B.73942. Switchbox. - B.73932. Dynamo. - B.73945. The distribution board is identical with the Bentley except that the "B" on the cover is replaced by RR. and the lower port for passage of conductors is blanked off. Sketch attached.
