Ignition Coil Testing For Previous part Click Part 1 Step 15  - After the mounting bolt has been removed, gently lift the coil from the plug well. Removing Ignition Coil Step 16  - After gently removing the coil from the spark plug well, insect the coil for any broken pieces or cracks in the housing which are an indication of failure. Ignition Coil Removed Step 17  - This next test will need a voltmeter set to ohms. Voltmeter Set To Ohms Step 18  - With the coil removed, attach the voltmeter leads to either coil terminal ( small wire connector.) Connect Voltmeter Leads Step 19  - Once the volt meter is connected obtain the reading provided, if this ignition coil was bad the reading would much higher. Coil Ohms Reading Step 20  - After reconnecting the ignition coil to the wiring harness, observe the electric...

Ignition Coil Test Testing Car Ignition Coil Tools and Supplies Needed Voltmeter Test light Socket set Wrench set Needle nose pliers Shop towels Protective eyewear and gloves Small wire or paper clip Screwdriver set Helpful Information An ignition system ignites a fuel/air mixture inside the engine's combustion chamber at the optimal moment in the pistons compression stroke. This timing is designed to produce the most power while emitting the least amount of emissions. There are many configurations of ignition systems but all operate on the same principle, create a low energy field and collapse it onto a high energy coil that transfers electrical energy into the secondary ignition system, i.e. coil, wire and spark plug. The system is activated by the primary ignition system, most use a low voltage trigger system i.e. crankshaft position sensor (CKP). This low voltage system (1.0 to 2.0 volts) is increased to 12 volts by using an amplifier which is located in...
