Kawasaki 4 wheeler

I just acquired a Kawasaki four wheeler. The key switch is missing and
it has a toogle switch for a shutoff I assume. I'm not getting any
spark. It is a Kawasaki Differential. I don't know where to look for
the model.
When the toggle switch makes contact to both wires it is a bout a 14ga
tan and a 14 ga white. Do you have to have a hot run somewhere to
energize someting.
In essence, what I'm asking , is how whould I hot wire it or check why
it's not getting spark to the spark plug. New plug.
