I just acquired one of these last week and the original bike calls for a 6v battery, which didn’t power the starter at all. I then got an 12v and started instantly. originally I don’t think this came with an electric starter. I think somebody converted it, but none of the lights work and there’s a separate cable that goes from the negative up to the starter button and there’s still the two that go on the positive terminal of the battery. But no lights work at all, no turn signal or nothing, not even clicking when you turn the blinker on.
