The other end of the primary goes to a primary binding post and the other end of the secondary to the secondary binding post of the coil as shown in Fig. 137. An Fig. 139.--Wiring diagram for four-cylinder engine. external view of a three-terminal coil for a single-cylinder engine is shown in Fig. 138. In Fig. 139 a four-unit coil with the wiring for a four-cylinder engine is shown. The three terminals are lettered: S, the secondary terminal leading to the plug; P, the primary terminal to the timer; and B, the terminal connected to the batteries. The secondary circuit is from the secondary terminal to the plug, across the gap into the engine frame, back through the timer to the coil. The primary circuit is from the batteries, one side of which is grounded, through the coil, to the timer, where the circuit is grounded and the current returns to the batteries through the metal of the engine. Where a multiple cylinder engine is used, it is customary to use a coil for each cylinder. The coils are usually enclosed in an upright box as shown in Fig. 140, which is a coil set for a four-cylinder engine. In Fig. 141 is shown the arrangement of the ignition system for a four-cylinder engine using dry batteries as the source of current. There are two sets of batteries, one service set and a reserve set. The six cells are connected in series, giving a voltage of about 9. The four coils are placed in one box, with two small terminals at the bottom. Either of these terminals is a primary terminal for any one of the four coils and is connected to the two sets of batteries. The switch on the front of the box determines which set of batteries will be used. The other primary terminals at the top of the coils are connected to the four bin...Read Less
