Hi I have an issue with my Daelim Daystar Vl125. The ignition fuse keeps blowing when accelerate. I have done some tests but cannot find the issue. I would appreciate if anyone can help. 1. I replace the 15 Amp fuse and bike start fine. 2. Turn of the ignition and start again fine. 3. As soon accelerate the fuse blow and tachometer , lights all is off. 4. I replace the fuse again and as soon turn the ignition on fuse keeps blowing strait away. 5. If i leave the bike for few hours and replace the fuse same happens again from p 1-4 Many thanks
