[INFO]how the ingition works on GY6 ? check thread

[duke11]

Hey guys,i have a question about my gy6 125cc XINLING TXM 125
how the electricity makes the chain ?

As i spot : when i turn the ignition key,it's just in state that power comes from battery,when i start cranking engine with electrical starter it turns the stator and stator generates power which goes to CDI and to spark plug ?

Just check this image below: would it be possible to determine if the stator works by checking those wires getting connected to CDI ?
My idea is to take a multimeter, connect it to those wires and when cranking engine see if electricity comes out.
By the way - is this the real GY6 125cc engine diagram ? I wonder so,cause my scoot has no side-stand option + trunk light or trunk switch or either that side stand switch.



p.s i got that diagram from : www.firenzee.com/gy6/Wiring%20Diagram.pdf

It looks like the drawing is for a 250cc not a 125cc.

The stator in the diagram has three yellow wires, so it is likely 3 phase.

You should have a yellow and a white wire and a red and black wire running to the CDI. There could also be a wire going to the enricher etc...

This diagram is probably closer but the wire colours could be different...

Thanks bro,i hope it helps,i don't know i can't see the 3rd wire on the diagram which is found as ground on the 4-pin socket

What colour is it? All solid green wires are grounds and so are a few solid black wires...

In general, GY6-150 colors

Green = Ground
Red = +12v Battery
Black = +12v Switched (ignition)

Off the stator -
Yellow = AC (1 = half wave, 2 = full wave, 3 = 3 phase)
White = AC - Lighting tap (not present in 3 phase, lighting tap provided from rectifier)

Red/Black = CDI Charge (can exceed 50v AC)(Only connected on AC fired ignitions)
Blue/White = Trigger Coil (harness colors vary)

Black = usually ground, though could be a phase in some oddball 3-phase systems (especially if a green is present)
Green (if present) = Ground.

See how easily it is to get confused? 50cc is the same except white is the charge power and yellow is the lighting tap, and it's almost always half wave.
