I have a 2000-ish Honda SH50. The battery is absolutely dead but I wouldn't mind because it starts easily with the kickstarter. However, I noticed that the indicators stop flashing and start lighting continuously when I hit the brakes. Tail light works but brake lights doesn't work. (I checked the bulb but that's okay so the problem must be something else.) What do you think can cause this kind of problem? Can it be the dead battery?
