Hi everyone! First time posting here. I have worked through some electrical issues on my recently purchased 78 or 79 xs400e (TL0) with the use of the wiring diagrams found on this site so thanks for that! When I got it, my main ignition switch was loose so I pulled it off to take a look and it pretty much came apart when I unscrewed it. Now I can't get it back together with all the parts that were in it. There's a little copper washer that I can't factor in. If I leave it out, the whole thing goes together fine. But if I put it in, then the whole thing binds and I can't turn the key. I couldn't find an exploded view of the assembly anywhere online so I'm hoping someone can help me out. Thanks!
