aerox running live ?

i was riding my aerox the other day and my fuel gauge was playing up and a few hours later my indicators were sticking, my electric start stopped working, my horn doesnt work and when i turn off my keys my bike still runs ! i think i may have to go around my bike checking why and where its not earthing out and running live. i just wondered if anyone had any other help/advice that they could give to help me mend the problem ?????????
