How To Test Ignition Coils with Basic Hand Tools HD
Click Here to Subscribe! http://youtube.com/carsntoys Website: http://carsntoys.net In this video I show how to test an ignition coil pack while the vehicle is running (via power balance test) as well as testing the coil pack while the vehicle is off. The power balance test is an easy way to verify if each cylinder is firing. If you do not hear a reduction in rpm when disconnecting the coil pack harness connector, then that particular cylinder is not firing. Check the ignition coil and the fuel injector (link below).Testing the ignition coil while the vehicle is off is an additional test to verify if the coil pack is indeed working or needs replacement.
