ok, so this has been hacked up by the p/o, they are cheap and not very reliable to begin with, i bet it is fried. I would try it anyways as you never know, and read up on as much as you can on cdi timing.
colors from stator to wires on the box:
red>grey
dark red>blue
brown>ground
yellow>lights
from the box hook the red to the ht coil, wire kill switch into this. black wire off the box goes to ground too. lastly make sure you use a regulator if you hook up lights as it will instantly blow the bulbs.
