This robust construction makes the tester reliable for professional mechanics and hobbyists alike, ensuring it can handle the rigors of automotive diagnostics.
    • Question: Can I use the Thexton THE404 Spark Tester for troubleshooting non-automotive equipment?

      Answer: While the Thexton THE404 Spark Tester is primarily designed for automotive use, it can also be used for any small gas engine equipped with spark plugs, such as lawn mowers, chainsaws, or motorcycles.

    Thexton Spark Plug & Ignition Tools Editorial Review

    The Thexton THE404 Spark Tester is a tool designed to test the strength of a spark in an ignition system. It performs the same function as inline ignition testers with a bulb, but with the added benefit of an adjustable gap, allowing for more accurate testing. However, it is made of plastic, which may not be as durable as metal. Additionally, some customers have found it difficult to use and see when checking for spark. Overall, it is a useful tool for testing spark strength, but there may be better options available.
