| -2- Contd. Coil, contact breaker and Distributor. The distributor and automatic advance mechanism are mounted on the cylinder head; the contact breaker having a three-lobe cam and two contact levers. The ignition coil is fitted on the dash, and the ignition switch to the steering column bracket. No ballast resistance is apparent. Lights. The head, side and tail lamps are controlled by a switch fitted at the centre of the steering wheel, as also is the push button switch for the horn. Two additional side (scuttle) lights are controlled by a small switch at one end of the instrument panel, while the [overtyped text] instrument lights are operated by a similar switch at the opposite end. Current limiters. Two current limiters are provided in place of fuses. These appear to work on the principle of the vibrator regulator and are intended to operate in the event of a short circuit or overload and limit the load current to 10 amperes. No conduit is used, the cables being protected in places by a sistoflex covering. EFC/C.A.Pignatt. | ||
