estimated guess on engine wiring

the yellow and white will be the output from generator and should give A/C voltage with the bike running

these goto the voltage reg which converts it to D/C

black/red is usually goes to cdi

green is usually earth to reg as well on jincheng engines


bike loom wire functions

black/white= neutral light
yellow/red= cdi
white/red= cdi
black=earth

there must be part of the bike loom with the 3 wires to hook up the generator output too trace it back from the reg under the seat


edit to add its gonna be trail and error to get the wiring right eliminate the neutral light and cdi wiring so u have a spark first
