KINLON GY2- HELLPPPP!!

Gday guys,

I just bought a new kinlon road trail and it has gotten to my place which I am now putting it all together. I have completed everything up until connecting the battery.... Seems like a pretty simple task right? Well There is a red battery lead which is thick and has a rubber cap which goes over the battery terminal (clearly this is the positive Battery lead), My issue is I cant see any other battery leads which have a rubber cap or anything that looks to be the Neegative battery lead. If anyone has a Kinlon Rt 200 (Purchased as that but it says GY-2 on bike) that could help it would be great!. Im assuming the green wire on the other side of the bike is the earth; However there is a black wire under the seat which has been nut screwed to the frame which I have no clue what it is...

I did mine last weekend. I thought the green wire would be the earth as well. The dude I was putting it together with suggested it was the negative, so we just went with that and everything works fine :thumbsup:

Or, just pull a fresh wire from the battery negative to nearest suitable frame opening you can find.
