In a generator, you reverse the process: You move a magnet past the armature to create electric current in the coil. A primary coil of perhaps 200 turns of thick wire wrapped around one leg of the U.A secondary coil of perhaps 20,000 turns of very thin wire wrapped around the primary coil. The secondary coil, having 100 times more turns than the primary coil, amplifies this voltage to approximately 20,000 volts, and this voltage feeds to the spark plug.
Electrical currents run through the ignition coil and transmit electricity to the spark plug. If you observe a spark jumping between the tips of the spark plug gap, it means the chainsaw coil is good. An ignition coil is an induction coil in an automobile’s ignition system that transforms the battery’s low voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel.

An ignition coil is an induction coil in an automotive ignition system that converts a low battery voltage into the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel. On the other hand, if the electric coil is physically intact, it may still work fine after a repair, so have tools ready to rewind the coil.

how does a chainsaw ignition coil work Related Question:
How do I know if my chainsaw coil is bad?
If your multimeter displays a reading of zero, it is an indication that you must replace the coil of your chainsaw at once because it has short-circuited. If your multimeter displays a reading above the specified level it is an indication that you will also have to replace the coil of your chainsaw because it is open.
How does a 2 stroke ignition coil work?
During upward stroke of a 2 stroke spark ignition cycle, the piston moves upward i.e. from the bottom dead center to the top dead center. While moving up, it compresses the air-fuel mixture in the combustion chamber. The upward movement of the piston creates a partial vacuum in the crankcase.
How do you test a chainsaw coil?
Pull the start rope on the chainsaw and watch the end of the plug as you do. If you observe a spark jumping between the tips of the spark plug gap, it means the chainsaw coil is good. If there is no spark, it means the chainsaw coil will need to be replaced.
What is ignition coil and how it works?
An ignition coil (also called a spark coil) is an induction coil in an automobile’s ignition system that transforms the battery’s voltage to the thousands of volts needed to create an electric spark in the spark plugs to ignite the fuel.
How does a 2 cycle chainsaw engine work?
A two-stroke engine, as explained in How Two-stroke Engines Work, has no valves or cams and generates power on every rotation of the crankshaft (twice as often as a four-stroke engine). This feature of the two-stroke engine means that it can generate twice the power of a four-stroke engine of the same displacement.
What should the Ohms be on a coil?
You should have a resistance reading of at least 3-4.5 ohms. A bad coil will show a higher reading then 3-4.5. Next, place the red or black lead from the meter to the centre of the coil , and to either one of the terminals positive or negative. You want 9500-10000 Ohms, a little less is ok but no more.
What wires go to the ignition coil?
They usually required only three wires: the spark plug wire, the power wire and the ignition switch wire. Ignition coils of this type are usually a little larger than a soda can and are heavy because of the metal core and the field coil windings. These coils are also filled with oil for temperature control.
What would cause no spark from coil?
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
Can you test an ignition coil with a multimeter?
Ignition coils have two circuits that require checking; primary and secondary circuits. Connect the multimeter to the negative and positive terminals of the ignition coil to get a primary circuit reading. If the multimeter shows a reading of 0 ohms, the ignition coil has shorted and needs replacing.
What is the gap between ignition coil and flywheel?
Replacing Ignition Coils or Armatures An ignition armature must be set at a precise distance from the flywheel. Your engine repair manual will provide the proper gap for your engine. Common armature gap ranges are . 006 – .
How does a chainsaw Carby work?
The carburetor on a chain saw is pretty simple, as carbs go, but it’s not entirely uncomplicated. The job of the carb is to accurately meter extremely tiny quantities of fuel and mix it with the air entering the engine so that the engine runs properly.
What happens if you put too much oil in your 2-stroke?
Excess oil can produce a smoky exhaust, oil leaking out of the muffler, and sometimes loss of power. While not ideal, these issues can be fixed by simply replacing the fuel in the tank with properly mixed fuel. But running a two-cycle engine with too little oil can actually destroy the unit.
Is a chainsaw 2-cycle or 4-cycle?
Chainsaw engines come as either 2-stroke or 4-stroke versions. Sometimes these are also referred to as 2-cycle and 4-cycle engines – it’s the same thing.
