It serves as a step-up transformer because it raises the 12 volts battery voltage to thousands of volts.

It's a conductor component that distributes the output from the coil to the spark plug according to the firing order.

It provides a source of energy to supply current to the ignition primary circuit for initial starting purposes.

iT controls the current flow to the coil during normal operation.

It serves as a step-up transformer, which raises the nominal battery voltage of 12 volts up to the many thousands of volts

It is used to close or open the primary circuit

It is used to reduce the amount of arcing when the points open the primary circuit.

It is used to reduce the amount of arcing when the points open the primary circuit.

It is used to distribute the surges of high voltage available to the coil tower

It is used to connect the high voltage surge to each spark plug

It provides a predetermined gap within the combustion chamber so that each time a high voltage surge is delivered, a quality spark will occur in the combustion chamber.

It controls the timing advance by the engine load.

It connects or disconnects the flow of electricity to the ignition system.

It is a system that delivers spark on the combustion chamber?
