I've got no spark on cylinder 3. Swapping the output leads on the CDI box for that cylinder does nothing. Swapping it with a lead from the other box makes it fire. Does this mean that the box is bad? You can see a very tiny spark when cyl 3 is connected to the correct CDI box. I've tried doing the tests recommended in CDI manual, but it is confusing. I have a good DMM and DVA.
