Manco Talon ATV

Trying to help a friend figure out why his has no spark. He lost the manual, 
dont remember what yr it is.

Found a PDF online for a 2007 but not sure thats the year on this one.

Any other way to ID it or locate a manual?

Last mechanic that worked on it said he put in a "wiring mod" and the wiring 
on these things is a mess.
