I tried lifting the fuel tank tank and checking the connections. They seemed alright. According to the charger the battery was fully charged. And the starter cranked the engine easily.

I tried cleaning the connections for the ctek charger quick connection and at that stage everything looked alright. I turned the ignition on more times, and everytime it worked perfectly.

After refitting the tank I connected the cdi (I not sure if that is the right name, but it's the black electrical thing under the fuel tank on the left side) and tried starting the bike. And the same thing happened. I heard just a "click" and all the power went. Now I back to where i started and can't get light in the dashboard at all.

What do do?
