I have an old qt50 not sure what year it is but i just replaced a few things on it like a spark plug, and a little metal cylinder that plugs in by the horn and such. I also went through all of the connections to make sure they were clean and tight. I started it up but then i noticed none of my blinkers worked. They didn't work well before because they didn't blink. Does anyone know what the problem might be? The headlight and taillight work fine.
