I was trying to fix my brake lights, somehow touched one of the wires on the hand switch and now have no power to the whole bike.  help please. nothing comes on now.  

You probably took out your main fuse, find the fuse on the bike check it with a continuity tester to see if it is good. If you do not have a tester our you do not know how to do that just go down to the parts store and get a new fuse. Do not over size the fuse.     Good Luck.
