Open exciter coil ? Help

Hello everyone.
I bought a 110cc xmoto pit bike four months ago. Now it won’t start.
I removed the spark plug, made the body of the spark plug contact the chassis and started it, but no spark was present. I tested the coil with a multimeter and seems ok. I was looking to replace the cdi and coil together. But I decided to check out the exciter stator and this seems to be open.
it turns out that the dc resistance measurement between ground and the black/red wire is OL or infinite.
but dc resistance between ground and the trigger pin is fine 130 ohms. I attached an image that shows the two points that show an open coil!
I am new to troubleshooting bike’s electrical systems.
It is clear that one side of this coil is attached to the green ground wire. The other side is the black/red exciter
Does anyone have this type of stator?
can someone help?

Five wires,
Two yellow
One green , this one has continuity to chassis and to one side of the wrapped coil.
One gren/white, this one has continuity to the pick up coil , reads 130 ohms
And one black and red, this one goes directly to one side of the wrapped coil ( shows open)
Thank you

After an Xray inspection of the coil was performed:

My shed is starting to look very underpowered right now.

Bit of an upgrade from the fag papers and lump hammer that I used to fix faults with.
