Got a 04 400ex that has no spark. Been trying to figure out what is wrong with it for about 6 months now. I have replaced the stator, cdi, rectifier, the stator pickup, and coil. I have stripped my wiring harness to check if there were any broken wires. Nothing wrong with main harness or the start/kill/light switch that I can see. Tried a few things I've seen on forums. I don't know what else it could be. I'm stumped and I have worked on multiple 400exs and never have had this problem before. If anyone could help me out, that would be great.
