Testing spark plugs with an ohmmeter is a simple procedure that can help you determine if they are functioning properly. An ohmmeter is a device that measures electrical resistance, and it can be used to test the resistance of a spark plug’s electrode. A spark plug is a device that creates an electric spark in an internal combustion engine, and it is essential for the engine to run properly.
To test a spark plug with an ohmmeter, you will need to remove the spark plug from the engine. Once the spark plug is removed, you can use the ohmmeter to measure the resistance between the center electrode and the ground electrode. The resistance should be between 2,000 and 10,000 ohms. If the resistance is too high or too low, the spark plug may not be functioning properly and should be replaced.
