The starter circuit does not employ an earth return as the conductivity of the chassis cannot be relied upon for heavy currents where voltage drop is of the utmost importance. The Lamps are connected up to independent terminals mounted on insulation and fixed to the frame or other convenient member. The terminals are of a suitable spring type so that any lamp together with its short length of lead may be removed from the car without trouble. This arrangement obviates the use of Adaptors which are a source of frequent trouble and the wire entering the lamp may be permanently connected to the bulb holder. A chassis terminal and connector is shown in Fig.11. | ||
