The most sophisticated of all ignition systems. The Coil On Plug Ignition System places an ignition coil; directly on the top of each spark plug. As a result, the Coil On Plug Ignition System; eliminates the need for distributors and spark plug wires.

What does an induction coil do for a spark plug?

An induction coil is a spark coil that produces a high voltage from a low voltage supply. The job of the ignition coil is to transform the battery’s lower voltage to a much higher voltage that is needed to create the electric spark in the spark plugs. The spark created will then, in turn, ignite the fuel.

How many Sparks does an ignition coil produce?

A larger ignition coil can produce about 40 kV. These coils can be mounted on top of the spark plug, and are called a direct ignition plug. Coils can also serve two spark plugs, and are called the wasted spark system. The wasted spark system consists of one coil generating two sparks per cycle to each cylinder.

Where does the distributor connect the spark plugs?

The distributor connects all of the spark plug wires. Most newer cars do not have a points switch, so that terminal is connected to ground or the negative terminal of the battery. On vehicles made before 1980, connect the points wire to the negative terminal of the coil.
