The cover protects the unit from dust, and the conduits protect the wires from accidental injury. = TV DISTRIBUTOR HEAD TO SPARK PLUGS Fig. 159.--Wiring diagram, Cadillac Eight ignition system. Figure 161 is a sectional view of the ignition unit showing the distributor at the top, the timer or interrupter below, and the automatic spark advance mechanism in the bottom. The condenser is mounted on the right-hand side of the unit in a waterproof casing. The spark timing is controlled automatically by the automatic spark advance mechanism which advances or retards the position of the timer cam relative to the driving shaft, as the engine speed increases or decreases. A spark lever at the steering wheel is provided, however, by which the timing may be Fig. 161.--Sestional view of Cadillac Eight ignition unit. further advanced or retarded. This spark lever is connected to the manual control lever at the left of the distributor housing. The timer or interrupter used on this system is shown in Fig. 162. The striking feature of this timer is that it employs two sets of contact points. The eight-lobed cam on the timer shaft operates two contact arms. These contact arms and the contact points are connected into the circuit in parallel, as shown in the wiring diagram Fig. 159, and each set of contact points handles but one-half of the primary current, thus reduc ing the wear and also the pitting and burning of the points. To accomplish this, however, it is absolutely necessary that both sets of contact points be adjusted to open at exactly the same instant and exactly the same amount. The proper distance betwe...
