Do you keep Burning Out Ignition Coils? Here is Why!

　　Have you just replaced the burnt out ignition coil and the new ignition coil is also burned out? This is why!

　　The main reason for the premature failure of the ignition coil is the wear or damage of the spark plug ignition cable.

　　The resistance of the damaged spark plug ignition cable will be much higher than the normal resistance. This high resistance causes a very high voltage in the secondary winding of the ignition coil. This excessively high voltage generates a lot of heat, which melts the wire insulation of the coil.

　　Remember, voltage = ampere x resistance

　　Remember, when you are dealing with an engine, it is best to determine the cause of the failure before purchasing parts to avoid costly repetitive failures.

　　Every spark plug in your car has an ignition coil, which can be connected to the spark plug with a wire or can be found on the spark plug, so no wires are needed. Your car must have a powerful and efficient ignition coil to generate enough electricity to generate sparks to ignite the fuel. Problems with the ignition coil system can cause problems such as low fuel consumption or engine misfires.

　　Sometimes, a bad ignition coil may be due to other problems, such as low voltage or high voltage batteries. In addition to poor performance ignition coils, troublesome car batteries can also cause many other problems. When you install a new battery, all of these will disappear.

　　This is especially true for batteries in old cars, as these failures are caused by battery aging. Please note that a good battery should read at least 12.65 volts after being fully charged. A reading below this value may indicate a problem with the car battery.

　　How to test the ignition coil

　　You can safely test the ignition coil by following the steps below:

　　Turn off the engine to avoid any accidents.

　　Open the car hood and check the ignition coil. Since the location of the ignition coil varies by car brand and model, please check your car manual or find important resources online.

　　Disconnect a wire from the spark plug and use the socket to remove the spark plug.

　　Reinstall the wire on the spark plug.

　　Place the threaded part of the spark plug on any exposed metal part of the car.

　　Remove the fuel pump relay or fuse of the car.

　　Ask someone to turn the ignition key of the car.

　　If you find blue sparks when the spark plug head touches the metal parts of the car, it means that the ignition coil is working.

　　If you are not satisfied with checking or testing the ignition coil, please ask a professional to perform this operation for you.
