An automotive ignition coil is nothing more than a transformer which has been designed and manufactured for a specific [dedicated] application.
It consists of two coils of transformer wire, arranged around a "soft iron" metal core.
The "Primary" winding is fed with 12 Volts DC from the vehicle battery. The "Secondary" winding [having MANY more turns of wire] is the "output" end of the transformer. The greater the difference in the number of "turns" between the two coils the greater the voltage output is increased.
The way an ignition coil works is that when the distributor "points" are closed, electrical current is allowed to flow through the Primary coil winding. This flow of current creates a magnetic field around the wire which is induced into the metal core.
When the points open, the flow of current is turned off, causing the magnetic field to "collapse." The collapsing magnetic field in the Primary winding and core "induce" a VERY high voltage current flow in the Secondary winding, which is then distributed to the proper spark plug by the rotor in the distributor.
Believe it or not, there is a coil of wire inside. Actually, there are two coils of wire. One has hundreds of times more wraps than the other and they are wound around a steel armature and cooled by oil that fills the space around them. The one coil with the fewer wraps is called the primary winding. When current is applied to the primary winding and then removed it creates a temporary magnetic field that induces current to flow in the secondary winding. Since there are many more wraps on the secondary, the voltage is increased from 12 volts on the primary to thousands of volts on the secondary. With that much voltage, the coil can create a spark that will jump several milimeters across the gap of the spark plug and ignite the fuel/air mix in the combustion chamber of the engine. The coil is a type of transformer. Since it increases voltage, it is called a step-up transformer.
The primary function of an ignition coil on an internal combustion engine is to furnish the high voltage required to jump the gap on a spark plug in an internal combustion engine, thus providing ignition of the air/fuel mixture in the combustion chamber.
It is a special form of transformer used to multiply the low voltage used in most vehicles (6 0r 12 volts) up to a much higher voltage, possibly as much as 50,000 volts or more.
Sucks dick like KARSI WHAT A FEG
You mean, I think, ignition switch module, which is the location of the ignition switch.
Why is gasoline coming out of the ignition switch?
diagram colors to conest ignition switch
what about the ignition switch wiring
when you start the car up that's your ignition switch is located...
Some motorcycles have a separate switch for the headlight that works independently of the ignition. If this is not the case, then there might be a short in the wiring for the headlight.
Your brake light ignition switch should be replaced. It works your brake lights and ignition switch, so you do need it. It only costs about $7 dollars.

Ignition switch worn and needs replacement
Remove the ignition switch retaining ring. Pull the ignition switch out. Remove the wiring harness from the back of the ignition switch. Reverse the process to install the new ignition switch.
Begin by removing the retaining ring at the top of your ignition switch. The ignition switch will slide out and you can remove the wiring harness from the end of the ignition switch. Reverse the process to install your new ignition switch.
Attach the wiring harness to the and of your 1986 Chevrolet Caprice ignition switch. Slide the ignition switch into the ignition slot. Tighten the ignition switch with the retaining ring.
The 1992 Plymouth Cold ignition switch is held in place by a retaining ring. Remove the retaining ring at the top of the ignition switch. Pull the ignition switch out. Remove the wiring harness from the ignition switch. Reverse the process to install the new ignition switch.
You can change your 1995 Chevrolet ignition switch by removing the ring at the top of the ignition switch. Slide the ignition switch out and remove the wiring harness. Reverse the process to install the new ignition switch.

A jet ski for your ignition switch?
switch engine off wait 15 seconds then switch ignition back on. it works on my car.
