First up the motorcycle in question is a Skyteam V-Retro 250 (V-Raptor in some countries). On the way home last night I noticed that my tail lights weren't working so I bought a new bulb like I had done before and when I opened the tail light housing a few screws fell out and a wire (presumably earth) and after I changed the light bulb non of the electrics are powering up when I turn the key.
I wasn't sure what to connect the earth wire to and tried a number of places and just from looking at the old light bulb I am thinking that it was not the reason for the rear light not working as it looks fine.
Now when I kick start the bike all the lights apart from the tail work but as soon as I kill the engine none of the electrics work, I can't turn on lights or use the electrical starter etc.
I have had a look at the battery terminals and cleaned them and they look in order but as much as I don't mind tinkering with the bike I don't know anything about wiring or the electrical bits so not even sure where to start.
Any ideas would be very much appreciated!!
