Decisions on radiators, ignition systems, and electrical components for cars.

| -3- Regarding the radiators, it is proposed that these are not to be made, but that the round tubing for their manufacture should be secured, so that they can be used up in our own Works, or at any radiators makers as required. It is desired that a smaller and lighter pattern if ignition coil be used for these 300 cars, and all future cars. That the trembler shall be of the Carpentier pattern. It was agreed that all these cars should be fitted with electric self starters, the same as on 7-CA, but constructed for six volts, which voltage was found quite satisfactory on the Peerless starter. That we obtain from Lucas' a slow speed dynamo and suitable switchboard for this voltage, which will permit of ample diameter of belt pulley, and generate sufficient current for the lamps at a car speed of 15 miles per hour of less. This will represent a dynamo which cuts in at a speed of 750 revs. per minute or less, i.e., belt pulley ratio of not more than 1.5 to 1. In the starting equipment, the whole of which it is agreed we make, except the batteries, the winding will have to be modified for the six volts, and twice the current and the magnetic switch of the new pattern, and single press button, should be made up at once, so as to be proved thoroughly before manufacture commences. In the meantime I advocate that we get together a substantial electrical department, largement composed of female labour for the production of these and other electrical apparatus, which our work demands.
