how to build a coil How to Test Ignition Coils

The preparation of the ignition coil test the first thing you want to do is always to take the necessary precautions.When working near or around the running engine, you must be very careful.You should pay attention to any loose clothes.If you have long hair, you should be careful that it does not come into contact with any part of your car's engine and its moving parts.Testing the ignition coil on your car is one of the tasks that is fairly easy to perform.It is not complicated and does not require any special tools or equipment.One thing to keep in mind is that your ignition system generates a lot of power.If something goes wrong, the result can be very dangerous.Act cautiously.If your coil has been removed from your vehicle and you need more specific data about the coil, you can do what you call a bench test.Set the Workbench test by removing a spark plug lead from the plug.Then remove the spark plug with the plug socket.Now you want to connect that spark plug back to the spark plug wire.Do it very carefully;You don't want anything to fall into an empty spark plug opening or you will have a problem.Ignition coil test: Bench Test: Grab a pair of insulated pliers.Hold the plug wire with insulated pliers.Now you need a ground point, so look at your engine.You want a place that is easy to access and exposed to metal.You can even do it with the engine of the car.Hold the spark plug wire with insulated pliers and contact the ground point of your choice with the threaded part of the spark plug.Let some people start your car engine and pay attention to the gap between the Mars plugs.You're looking for a bright blue spark to skip the gap-Electricity.Even during the day, if you can clearly observe this blue spark, then your spark plug works well.Test the ignition coil: Multimeter test you can do many other tests on the ignition coil.However, if you want accurate information about the state of the ignition coil, then you should do a Multimeter test.This test is much more accurate when determining whether a coil needs to be replaced.It is considered the only correct test of the coil.You can rely to a certain extent on the bright blue sparks you see in the bench test, but if this spark is a bit faint, your eyes can't really judge, using this spark plug can cause your vehicle to travel rough or incorrect, which is the last thing you want.Put it in the FireWire circle for a while.The ignition coil contains two coils at the top of each other.We call these coils winding.There is a primary winding, the first wire and the second wire.The primary winding collects electricity to generate sparks.The secondary winding is sent to the dispenser.Any one of these windings is likely to fail, causing the ignition coil of the vehicle to fail.Sometimes the ignition coil will fail completely, which means it will never produce any spark.The Multimeter test is carried out when the ignition coil is completely disconnected.The meter provides numbers to help you determine the status of the coil-More reliable than visual assessment.There are different types of digital multimeters that can be found online or at local car repair retailers.Of course, to use a multimeter, you must know the resistance specification of the ignition coil.If you do not know what they are then please refer to your vehicle service or repair manual for this information.Test winding xa4 test the primary winding of the ignition coil: As mentioned above, the primary winding of the ignition coil first collects power or voltage from the car battery.Have you found the resistance specification of the coil?You need this before performing a Multimeter test.If you don't let them take a moment to find your service or repair manual.After finding the resistance specification, find the digital multimeter.If you have a conventional round coil, you need to use a multimeter to place the lead on the outer small rod of the coil.If you have a newer closed unit, place the lead on the indication or marking rod of the coil.Observe the readings you get on the multimeter.If the multimeter is read in the range according to the specifications in your manual, then your main winding is working properly and you can continue to check the secondary winding.If you find that the reading is even slightly out of range then you should replace the coil.To test the secondary winding of the ignition coil: the secondary winding of the ignition coil sends the spark to your dispenser and then to the spark plug.A faint spark or no spark at all indicates that the coil needs to be replaced.To test the secondary winding of the ignition coil, connect the probe to the external 12 v and center pole of the ignition coil.The center bar is where the main line connected to the dispenser is located.Again, check the readings to make sure they meet the range set out in the car service manual.Everything is fine if your coil is in this range.If the reading is even slightly out of the specified range then you should replace the coil.Keep in mind that the failure of the ignition coil can cause the engine to run rough and cause other problems as well.
