Testing an ignition coil and not using a multimeter requires a unique strategy. Ignition coils are important elements of an engine’s ignition system, accountable for changing the automobile’s battery voltage into excessive voltage required to create a spark within the spark plugs. A defective ignition coil can result in varied engine points, together with misfires, diminished energy, and issue beginning. Whereas a multimeter is a generally used device for testing ignition coils, it’s doable to evaluate their performance with out one.
One methodology includes utilizing a spark plug tester. A spark plug tester is an easy device that connects between the ignition coil and the spark plug. When the engine is cranked, the spark plug tester will point out if the ignition coil is producing a spark. If no spark is current, it may point out a defective ignition coil or different points within the ignition system.
