If you go to yahoo.com/groups and look up the GN400 group you'll find all kinds of details on wiring, ignitions, service manuals, mods, etc. Myself and a core group of members have done quite a bit of work on these GN400s.
My next test will be of a CDI for a newer model GN250. I found one on ebay for $30. Worth a try.
