| X4410 Extract from EP {G. Eric Platford - Chief Quality Engineer} 7/H19.7.23. X.4421. X.4410. Re 20 HP. ELECTRICAL TROUBLES. X. 4338. -------------------------- CUTOUTS AND DISTRIBUTION BOXES. Several of these have been returned having failed in service. The last one was returned to Mr. Brock on the 18th inst. see memo EP {G. Eric Platford - Chief Quality Engineer} 14/H18.7.23. In one or two of these cases, we are assured that it has been due to faulty batteries or battery connect ons, and in other cases due to faulty action being taken when changing over to the magneto ignition. We have also traced faults of the distributor box due to faulty connections, as we have found the terminals "come" loose, which we suspect is due to the action of the temperature on the insulating material, which we feel has been largely overcome by the fixing of spring washers over these various connections. We feel that more attention should be given to the importance of locking the various electrical fittings in this distribution box, as we have a number of cases where the coils and the bobbins have become loose, also other cutout fittings which have been such as to affect the cutting in position of these cutouts. | ||
