All this little setup is made up of is two 30 amp test clips. I got mine off the Mac Tools truck for about $1.50 each. For $3.00 you have a nice little spark tester. The way this works is, you take the screw out of the end of one clip and screw both clips together as shown above. Then, you clip one end to the metal portion of the spark plug and the other end to the head of the block. Then, pull it over and see what type of fire you have. The reason behind this is, you don't have to hold the plug on the block and risk shocking yourself. This is also good for 2-cycle engines that will ruin the ignition by pulling the engine over without the plug being grounded. Hope you like, ENJOY!
