The ignition coil is the feelings of an automotive Glimmer ignition manner, on the contrary is essentially honorable an electrical transformer. It consists of a important coil fabricated up of One hundred to One hundred fifty turns of substantial copper wire and a secondary coil made up of 15,000 to 30,000 turns of useful copper wire.
Function
The valuable coil creates, or induces, an inordinately altitudinous voltage in the secondary coil.
Testing
You can test the resistance of the primary and secondary coil windings with an ohmmeter, with the battery lead to the ignition coil disconnected. You need to refer to the manufacturer's specification for your specific ignition coil, but typically primary coils have a resistance between 8,000 ohms and 20,000 ohms and secondary coils between 0.5 ohms and Two ohms.This causes a spark in the spark plug, which ignites the mixture of fuel and air in the engine.
