Immediately after the Civil War, they sought to give meaning to freedom by reuniting families separated under slavery, establishing their own churches and schools, seeking economic autonomy, and demanding equal civil and political rights.
An ignition coil (also called a spark coil) is an induction coil in an automobile 's ignition system which transforms the battery's low voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel.uch smaller coils are used with one coil for each spark plug or one coil serving two spark plugs (for example two coils in a four-cylinder engine, or three coils in a six-cylinder engine). A large ignition coil puts out about 40 kV, and a small one such as from a lawn mower puts out about 15 kV.
To turn primary circuit back on, the ignition switch must be turned to the START position. On the Dura-Spark II system, the ignition primary circuit is on any time the ignition switch is on. SOLID STATE IGNITION. When ignition switch is on.primary circuit and ignition coil are energized. As distributor shaft rotates, the distributor generates a signal that causes electronic control module to break the primary current and induce a secondary voltage in coil.o turn primary circuit back on, the ignition switch must be turned to the START position. On the Dura-Spark II system, the ignition primary circuit is on any time the ignition switch is on. SOLID STATE IGNITION. When ignition switch is on.
