Spark plug leads are an essential part of an internal combustion engine. They connect the spark plugs to the ignition coil, which provides the electrical current that creates the spark that ignites the air-fuel mixture in the cylinders. Faulty spark plug leads can cause a variety of problems, including engine misfires, reduced power, and increased fuel consumption.
It is important to check spark plug leads regularly to ensure that they are in good condition. This can be done by visually inspecting the leads for any signs of damage, such as cracks, cuts, or fraying. It is also important to check the resistance of the leads using a multimeter. The resistance should be within the manufacturer’s specifications. If the resistance is too high, the lead will not be able to conduct electricity properly and will need to be replaced.
