Scooterotica

I have a new BGM V3 DC stator only I now want to use on a standard AC system, I have been given differing opinions what to do with the extra yellow and black wires, what is the correct way to deal with the extra wires, where do they connect to, I assume the black is to earth

One of the yellows goes to ground also. Does not matter which one.

If you look at the coils it's very obvious.

Thanks for that, as far as electrics go with me, there is nothing obvious!
