The ignition coil in your Dodge Truck is a compact, electrical transformer that increases the battery's 12 volts to as high as 20,000 volts. Such incoming 12 volts of electricity passes through the primary winding of about 200 turns of copper wire while raising the power to about 250 volts. This low-voltage circuit in your distributor is continuously broken by the opening and closing of the points and the interruption causing a breakdown in the coil's electromagnetic field. Everytime the field collapses, a surge of electricity draws through a secondary winding made up of more than a mile of hair-like wire twisted into 25,000 turns. Then, the current is boosted to a high voltage that’s needed for ignition and is then relayed to the rotor. Since the truck ignition coil in your vehicle is considered as the heart of the ignition system, you must ensure that you are using a quality one like a unit from Accel.
