Testing an ignition coil without a multimeter requires a different approach. Ignition coils are essential components of an engine’s ignition system, responsible for converting the vehicle’s battery voltage into high voltage required to create a spark in the spark plugs. A faulty ignition coil can lead to various engine issues, including misfires, reduced power, and difficulty starting. While a multimeter is a commonly used tool for testing ignition coils, it is possible to assess their functionality without one.
One method involves using a spark plug tester. A spark plug tester is a simple tool that connects between the ignition coil and the spark plug. When the engine is cranked, the spark plug tester will indicate if the ignition coil is generating a spark. If no spark is present, it could indicate a faulty ignition coil or other issues in the ignition system.
