| X 4338 To EY/RD. from EFC. {E. Fowler Clarke - Electrical Engineer} c. EY. EFC {E. Fowler Clarke - Electrical Engineer} 1/T21.1.26. RE VARIOUS SMALL POINTS ON PRODUCTION. (1) It is suggested that the spindle of the cutout lever should be made of stainless steel to prevent rusting which sometimes takes place, giving a tendency to jam. Cases have occurred on test cars and we ourselves have experienced this in one instance. (2) It frequently happens that the relative dimensions of the commutator end cover and the spring locking ring on a 20 HP. dynamo are such that the cover cannot be taken off over the ring. It should not be possible for this to occur in any instance, and we suggest wider limits, if these can be arranged. (3) The junction of the ballast resistance wires through their terminals eyes, and also the coil wires through the terminal eyes are not entirely satisfactory. There is a tendency for fracture of the wire to occur at this point, and on the coil wires there is a tendency for the braiding to fray away from the clip. It was understood that the fraying of the braiding was supposed to be prevented by the application of some stuff called 'gloy'. However, I have seen an untidy case of this on a production car, and surely it can be prevented. It was as if sufficient length of braiding were not included under the clip. Contd. | ||
