Coil test per manual. Primary coil test..- volt meter lead on spade that orange wire led goes to/ + volt meter lead on spade r/w lead goes to, should read 2.6ohms+/-20percent at 68 degree's. Secondary test..- +volt meter lead on r/w spade, negative volt meter lead at coil wire with spark plug cap removed, ( it unscrews counterclockwise) should read 11.9ohms+/- 20 percent at 68 degree's. Cut a small section of the coil wire ( to get a nice clean end with a nice inner coil wire showing) and screw in the cap, and see what you have for spark. Also, Yamaha "pigtailed" a small 18 gauge wire on the negative battery cable eye end at the starter/generator post. Cut back the electrical tape and put your own "eye let" end on the end of it. Reattatch it to the starter stud along with the negative battery cable and test spark again. Sorry, there is no test on the ignitor, if everything else check good...new ignitor is needed. If you didn't understand this....blame it on "Black Velvet and Pepsi"! good luck
