Review on Thexton THE404 Spark Tester: Enhancing ๐Ÿ”ฅ Ignition System Performance with Reliable Spark Testing by Dee Fadaifar

Revainrating 5 out of 5

Works great in spark plug and ignition tools

This tester works great. I use it to check the ignition spark on my Ford 8N tractor. I think it's good that you can adjust the gap width depending on the type of ignition system to be tested. There are instructions on the packaging to help you determine the correct width if you don't know what it should be. The only question I have is about durability as the ground terminal is tack welded, but so far so good.

Pros
  • Impressive
Cons
  • Not bad
