Testing spark plugs with an ohmmeter is a straightforward process that may make it easier to decide if they’re functioning correctly. An ohmmeter is a tool that measures electrical resistance, and it may be used to check the resistance of a spark plug’s electrode. A spark plug is a tool that creates an electrical spark in an inner combustion engine, and it’s important for the engine to run correctly.
To check a spark plug with an ohmmeter, you’ll need to take away the spark plug from the engine. As soon as the spark plug is eliminated, you should use the ohmmeter to measure the resistance between the middle electrode and the bottom electrode. The resistance ought to be between 2,000 and 10,000 ohms. If the resistance is just too excessive or too low, the spark plug will not be functioning correctly and ought to be changed.
