What is an ignition tester used for?

Ignition testers are used to diagnose problems in an engine's ignition system. They help determine if spark plugs are firing correctly and if there are issues with the ignition coil, distributor, or other components. By visually confirming spark, technicians can quickly pinpoint faulty parts and avoid unnecessary replacements.

What types of ignition testers does ToolSource offer?

How do I choose the right ignition tester for my needs?

Consider the types of vehicles you'll be working on and the level of detail you need in your diagnosis. A simple spark plug tester is sufficient for basic spark presence checks, while more advanced testers can measure coil output and diagnose more complex ignition problems. Brands like Lisle and KD Tools offer a range of options for different needs.

Can I use an ignition tester on modern vehicles with electronic ignition systems?

Yes, many ignition testers are designed for use on both older and newer vehicles with electronic ignition systems. However, it's crucial to select a tester that is compatible with the specific type of ignition system you're working on, such as coil-on-plug (COP) or distributorless ignition systems (DIS). Always refer to the tester's instructions and the vehicle's service manual.

What should I look for in a quality ignition tester?

Look for durable construction, clear and easy-to-read displays, and compatibility with a wide range of ignition systems. Features like adjustable spark gaps and built-in voltage meters can also be beneficial. Brands like GearWrench and Waekon Industries are known for producing reliable and accurate ignition testers.

Are there any safety precautions I should take when using an ignition tester?

Always disconnect the ignition system before testing to prevent accidental shocks or damage to the vehicle's electronics. Wear appropriate safety glasses and gloves, and follow the manufacturer's instructions carefully. Never test an ignition system near flammable materials.

What is a spark plug wire tester and when would I use one?

A spark plug wire tester is used to check the integrity of spark plug wires, ensuring they are conducting electricity properly. You would use one when diagnosing misfires, rough idling, or other ignition-related problems. These testers, some available from brands like S & G Tool Aid, help identify damaged or deteriorated wires that need replacement.

Do you carry any wireless ignition testers?

Yes, we offer wireless ignition testers, such as those from Ferret Instruments, which provide added convenience and flexibility during diagnostics. These testers often connect to a smartphone or tablet, allowing you to view test results and waveforms remotely. This can be particularly useful when working in tight spaces or when needing to monitor the ignition system while the engine is running.
