Ignition Tester

Avoid the Hassle of Ignition Failures
When you turn your key in the ignition, several processes are triggered within your car's engine. The first turn powers the battery, and the second turn connects the engine's spark plugs to the ignition coil and the battery. When two turns don't successfully prompt this connection, though, you'll need to do some research to discover what's wrong. An ignition tester is one of the most effective tools for identifying issues with your engine's spark plugs. The best ignition testers for cars and trucks are designed to simulate the trigger signal and test whether the ignition responds as it should. If so, you can continue seeking a resolution to the problem, and if not, you know that your ignition needs work.

Easy Operation

To use ignition testers near me, you'll need to disconnect your car's spark plug lead and connect it to the ignition tester. The Ignition tester is then connected to the spark plug as you start your engine. The gap between the ignition tester and the spark plug will indicate whether there is a problem. If you see a spark, your ignition is working properly, but if not, there is a mechanical issue to be addressed. Ignition testers vary in features and function, but finding one that's compatible with your ignition and auto make and model is important. You may also look for a model that tests coil operation or shift light operation if you are looking for additional information when you conduct your test.

Finding the Culprit

There are a few telltale signs that something is wrong with your ignition and spark plugs. If you notice that your fuel economy has suddenly and dramatically worsened, this might be a sign that your spark plugs are not consistently connecting the way that they should. Similarly, if you notice a cylindrical misfire, this is often due to spark plugs' failure to ignite the engine's air-fuel mixture. Regular wear and tear on a car is often the most common culprit. As you drive your vehicle, factors such as continual oil contamination, exposure to high heat, and the buildup of carbon can all cause spark plugs to become more worn and less effective. Eventually, you may need an ignition tester to see whether the problem is with the spark plugs or another part of your car.
