zongshen 'cb' 250 engine wires

[el-griffo]

hello, i just bought a zongshen 'cb' 250 engine to put in my hanway 125, it came with no info as to wiring and the company that sells them said 'we have no info' when i asked them!
what i need to know is what the wires are for that come from the engine as they are different colours to the engine on the bike i am putting it on.
the 'zong' has:-

2 x white which i know are the charging wires from alternator (polarity not an issue as AC).
1 x green - must be earth?
1 x black/brown
1 x blue/white

also has multi-pin socket/cable for gear indicator but that isn't a problem.

any info most welcome, thanks!

Take the multimeter find it out
1 Charging wires should be the 2 wires that had continuity btw them
2.Find out which wire had continuity btw metal is earth
3. pick-up coil / CDI's power source is very easy to distinguish (compare ohm or volt readings. They're very different !!!) once u ruled out [1 & 2]
