Car Ignition Coil Wiring Diagram

Wrapped around it is the secondary coil.

Car ignition coil wiring diagram. Discover how the current goes through the coil to the sparkplug. Dec 10 2016 automotive wiring diagram resistor to coil connect to distributor wiring diagram for ignition coil. Older model cars used the 12 volt ignition coils to provide power to the spark plugs. The ignition coil is the unit that takes your relatively weak battery power and turns it into a spark powerful enough to ignite fuel vapor.

When the ignition switch is turned or pressed the button to start position there will be a small current flow through the starter solenoid coil allow sufficient current flow to the starter. They usually required only three wires. Current flows from the battery through the primary winding of the coil. One winding is called the primary winding the other is the secondary.

Wiring diagram for ignition coil. The spark plug wire the power wire and the ignition switch wire. Usually the ignition switch connects with a key or a button and inside of it has the regular wire connects to the car battery. The secondary coil normally has hundreds of times more turns of wire than the primary coil.

The coil is a simple device essentially a high voltage transformer made up of two coils of wire. Inside a traditional ignition coil are two coils of wire on top of each other. Ignition coils of this type are usually a little larger than a soda can and are heavy. These coils had very simple wiring.

Explanation of how the ignition system of a car works in an automobile. It shows the components of the circuit as simplified shapes and the capacity and signal connections amongst the devices.
