New Brake Lights and now bike getting no power.

[mjs91882]

I went to put on the back off for my braking system for my klr 650, but while doing that now nothing seems to have power. I hooked it up he way it said then realized it wasnt working so played with the wires in the back by the brake light. Now im getting no power on the bike. It wont start or nor will the blinkers or anything come on. Im thinking the Battery might have died due to a short or something from my mech uninclined self. Any suggestions? 2008 kawasaki klr 650 thanks
