Testing spark plugs with an ohmmeter is a straightforward process that may provide help 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 have to to take away the spark plug from the engine. As soon as the spark plug is eliminated, you should utilize the ohmmeter to measure the resistance between the middle electrode and the bottom electrode. The resistance must be between 2,000 and 10,000 ohms. If the resistance is just too excessive or too low, the spark plug might not be functioning correctly and must be changed.
