This little gadget is a lifesaver when it comes to quickly diagnosing a no spark condition. Clear as day you can see if you have spark or not, just place it inline between the spark plug and the spark plug boot(wire). Works great for diagnosing 2 stroke or 4stroke gas engines. Very handy to have and nicely priced. Great quality too.
