Triumphrat

Hi all --

I'm a new Triumph owner -- just bought a 2007 America. About a week later the battery died. So I managed to get the battery out to recharge & test it, but just barely. The screw on the negative battery post has almost no clearance and was a royal pain to take out. To get the screw back in, I think I'll need to take the seat off. How do I do that? The manual offers no help. I can't find anything online, either. Can anyone give me advice on how to get the seat off. Or better yet, is there some way for me to get that screw back into the negative batter post without further dismantling?

thanks in advance.
