you guys are gonna love me! I am a certified tech and cant find work so, I may as well answer everyones concerns for free, why not? Cant get work so...That yellow wire does not connect to anything. The cdi box ending in 11 is the latest part number for it. There are no more in any of Yamaha's warehouses, best bet is to seach ebay. Unless you have an analog meter, one with a needle, you can not check output to the stator or going out of the coil, unless you have a special adapter for a digital meter.
