This is a wreck from someone's garage when he moved. No batteries when I got it, so I'm figuring it out. The problem is there's a red terminal, a black terminal, and a WHITE terminal. Someone tied the white wire over with the red one, doesn't have to have happened on the assembly line. I"m just wondering if it should hook to the positive battery the way it looks as though it had been. But the blurry picture in the owners manual looks like maybe it's connected on the negative side. The problem is, maybe not, this is really hard to base a decision on.

My gut instinct is that an extra line is an extra ground.

Anyone know how this bike works?
