There is no difference in the wiring of a horizontal double-opposed and a two-cylinder vertical 180° crank-shaft engine, as shown in Fig. 50, except that the timers are so built that in the first the two contacts are a quarter revolution apart, and in the second a half revolution.
In wiring a car with a single coil and secondary distributer the four contacts of the timer all lead to the primary terminal of the coil, the firing order being according to the manner in which the secondary terminals of the distributer are connected to the cylinders (Fig. 51).
Wiring for the make-and-break system is much simpler than that of the jump-spark, and when a magneto alone is used, it consists, as will be seen from Fig. 52, of only a wire from the magneto to the igniters, the other terminal of the magneto being attached to its metal base in such a manner that the ground connection is made when the magneto is secured in position on the engine. The firing order is according to the setting of the cams that operate the igniter tappets.
