Default Chinese 4 wheeler not getting spark

So I'm running out of places to go with this problem. My sons 4-wheeler isn't getting any spark I got all new electrical components still nothing, in this magneto/strater thing, sorry I'm horrible with names of things, it has 5 wires that connect to the harness, but there is a red/ green wire and a black wire that have nowhere to connect to alon either end, what are those for? Do they need to connect somewhere? Any help greatly appreciated
Red and black wires Im confused about

Odd, nearly all Chinese bikes use Honda wiring colours but that stator doesn't. Long black coil is for providing AC power for the spark, so AC ignition. Shiny copper coil is for providing power for the battery, small coil at the top of the case provides a "trigger" signal telling the CDI when to spark. So any wires from shiny coil go to the rectifier/regulator, this is single phase as only one battery power coil. All wires from black coils go to the CDI, only question is which goes where in the CDI plug. There should be a diagram with the new CDI telling you which does go where, if you trace them from the black coils. Diagrams are also in the "help diagnose stator" sticky in the Chinese engines section of this forum, but not all AC CDIs follow the same pinout.
