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.
Condensers, including those made of copper, steel or aluminum also develop leaks from acid eating through from the inside and winter road salt and/or salt water along the coasts causing deterioration from the outside. Acid will cause small pinhole leaks to develop in the condenser coil and the evaporator coil. Flaked off debris and sludge will flow to the bottom tubes of the condenser causing both restrictions and a concentrated accumulation of acid to eat at the coil. Sludge and debris at the bottom of the evaporator coil will not normally cause a restriction but will eventually cause reduced cooling efficiency.
