Those are all great testers and worth their weight in gold. I made a tiny set of jumper cables for open-air spark testing. It works especially well for open flywheel motors. Adding a spark plug with no ground electrode or a huge gap further helps identify ignition problems. I like the inline testers with the lights best because the flash is so large and you can run them on the boat without fear of starting a fire.
