I have performed those tests and it sounds like my coil, "My 1990 Honda Civic is very hard to keep healthy and running, so I'll need to fix it myself. Aftermarket ignition coils are built to different specifications and tolerances that can affect the performance of the ignition system. The ignition coil has both secondary and primary ignition circuit. Using a spark plug tester also means you won't expose your combustion chamber to debris. A spark plug misfire will immediately be evident in the tester window. This article concentrates on using a digital multimeter to test the Coil-On-Plug ignition coil with three wires in its connector. If you don’t have a diagnostic tool, you can remove the coils to test them instead. The ignition system coordinates the timing so that the spark will ignite the air-fuel mixture in the combustion chamber just as it reaches maximum compression in each engine cycle- thus, maximizing the engine’s power. The battery provides 12 volt electric current to the ignition coil, which generates electromagnetism in the ignition coil. Then start the engine and watch the tester window. IF you have a Volt/Ohm meter, you can do a couple tests. You'll also know for sure if what you have is a bad coil or if you need to spend money on further troubleshooting.

There are two kinds of test available to test your ignition coil, and they are, spark plug test and bench test. Rotate the flywheel to test and mark the magnets. The ignition coil transforms the 12 volt electric current from the battery into about 20,000 volts. It is located to one side of the flywheel so that when it spins and the magnets pass it, a charge is generated, then passed to the spark plug. It will, however, still be flooded with fuel, which may cause serious damage. Set the meter to 20K Ohm setting, and attach the leads to the ignition coil's center terminal. If it's working, the voltage won't go above 13.5 or 14 v. Keeping the voltage down when the engine revs is the regulator's job. Just make sure that you note which wire goes where so that you can put everything back together after you're done. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/9\/9c\/Test-an-Ignition-Coil-Step-1-Version-2.jpg\/v4-460px-Test-an-Ignition-Coil-Step-1-Version-2.jpg","bigUrl":"\/images\/thumb\/9\/9c\/Test-an-Ignition-Coil-Step-1-Version-2.jpg\/aid1517690-v4-728px-Test-an-Ignition-Coil-Step-1-Version-2.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"
