Tao Tao. What is this part called?
 

I will try and describe it as best I can, I have pictures but don't know how to post them. I have a tao tao quad with a no spark condition. I believe it is due to a part where the wiring is mangled. It is a plastic contactor plate with 4 wires going into it that is located directly on top of the drive sprocket. What is this called or what does it do?
