ive been having a lot of issues with my jonway 50cc2t since I got it a few months ago with 150 miles.first it was sometimes have the gas gauge working or not.seems like when my gauge doesn't go on the starter button doesn't work but will kick start.i had blinkers and horn and today my horn is barely working and when I turn on the blinkers they don't work and I hear a buzzing sound.i took the dash apart and checked all wires and checked my batt cables they are tight.so I have some kind of electrical problem but don't no where to begin
