ohk ive been riding this thing for over a year now, very strong and reliable little bike. the battery is totally dead. i actually ride it without a battery, as the battery is only for the lights, and signals i believe. would the battery also be somehow related to the horn? cuz theres a horn on it that doesnt work as well as a speedometer. do i need a battery to run those or would that be more of a problem due to wiring thats not hooked up? cuz when its running my lights will light up as well as a little light on the speedometer that will tell me if my highbeams are on.... theres a bunch of wires under the seat running all over that confuse me because some run to the lights, some to the speedometer etc, but the lights still work when its running... so would that mean my speedometer and horn would work as well if i had everything hooked up properly? what exactly should the battery do on this bike,?
