What sends power to the coil?

The battery powers the ignition coil with low-voltage energy. This causes other distributor components to move, causing the ignition coil to pulse and sending energy down each spark plug wire in sequence. Power flows down the spark plug wires to the spark plugs, causing sparks. The resulting explosion ignites fuel in the combustion chamber.

Coils are components used to transform alternating current (AC) into intermittent direct current (DC). They are usually constructed by wrapping insulated copper wire around a core material, such as iron or aluminum. The term "coil" also refers to the shape that results when you wrap copper wire around a core material; for example, a guitar pickup consists of a coil of wire on a magnet. Coils can also be called bobbins because they look like giant sewing threads. A single turn of a coil is called a pitch. A two-pitch coil has two turns of wire on one bobbin. A three-pitch coil has three turns of wire on one bobbin. And so on.

When electricity enters a coil from the battery, it causes the coil's parts to become magnetic. These parts include the core material which is wrapped with wire. As the name implies, the core material is made of iron or aluminum, but it can also be made of plastic or another non-ferrous material. The number and size of the cores used determine how many poles there are on the coil.

Does electronic ignition use a coil?

In an electronic ignition system, the ignition coil, like the battery ignition coil system, is utilized to generate a high voltage to the spark plug. However, in an electronic ignition system, this high voltage is generated by a semiconductor device called a 'transistor' which controls current flow to the spark plug. Therefore, instead of a magnetic path being used to pass current to the spark plug as in the case with a mechanical ignition system, an electrical path is used in an electronic ignition system.

This means that an electric circuit must be used in place of the original magnet-coil circuit in order for electricity to reach the spark plug. This new circuit must contain some type of switch that can open and close an electrical path from the battery to the spark plug. This switch may be anything that can connect and disconnect electricity; it may be a silicon chip called a 'transistor' or a metal contact called a 'plug wire'.

In general, the more sophisticated the ignition system, the more transistors it will have. Electronic ignition systems are now used in many large engines because they can control the timing of the spark plugs very precisely, which allows for better fuel efficiency and reduced tailpipe emissions.

What connects the coil to the distributor cap?

Two wire coils are layered on top of each other inside a typical ignition coil. The coil wire is routed via the big contact in the center (the wire that links the coil to the distributor cap). A 12V+ cable connects to a positive power source as well. Then, the other end of this cable goes to the distributor cap which sends out 6 volts to each of the two coils.

This system is called "distributorless ignition" because there is no longer any need for a distributor. Instead, when you turn the key to the on position, the signal will flow directly from the battery to the spark plugs without passing through a mechanical switch or distributor. This means that if someone could connect their radio to the car's power supply, they could listen to music while driving!

The first vehicle with this system was produced in 1964 by GM as part to new government regulations that required manufacturers to provide an anti-lock braking system (ABS) as standard equipment on all vehicles sold in the United States. Called "Distributorless Ignition - DLI", this system was included on several models including: the Buick Skylark, Cadillac Coupe Deville, La Salle, and Nova. Although not marketed as such at the time, it is considered the first true digital electronic ignition system.

How does the pickup coil produce signals for the ignition control module?

When the ignition switch is turned on, primary (battery) current travels from the battery to the coil primary windings through the ignition switch. As the armature's teeth approach the pickup coil, they generate a voltage that tells the electronic module to switch off the coil's primary current. When the engine is shut off, the magnetic field in the coil's core disappears, and so does the signal it produced when the switch was turned back on. The electronic module turns the coil back on again as soon as there's a possibility of the engine starting up again.

The diagram below shows how the pickup coil works during engine operation. When the engine is running, the magnet in the armature attracts the steel-core wire inside the coil's secondary winding, so the coil produces a voltage which keeps the electronic module enabled. After the engine is stopped, the magnet in the armature loses its attraction for the coil's secondary winding, so the electronic module disables the coil. When the driver shuts off the engine by turning the key out, the magnetic field in the core disappears, and so does the voltage that the coil produces after being re-enabled by the electronic module.

This disables the coil, preventing any further electricity from flowing through it and thus shutting off the radio. If the key is not removed within a few seconds, however, the engine will continue to run for a few more seconds under its own power.
