I had the good fortune to trashpick a little 25" Toro Wheelhorse sit down rider/tractor. It's got a 8 hp Briggs on it. Here's what I need help with - the battery for the electric start was missing. When I went to hook up the new battery, I could only find one red battery terminal cable. There's no other cable (ie. black/ground to be found and no signs indicate it's missing - like it never exisited). I followed the red terminal cable back and it junctions into what looks like some type of switch (maybe). A white cable exits the other side of the switch and goes to the starter motor. It appears to be the only lead into the starter. My question is, how does the battery hook up to this model. If any one can tell me I'd be very appreciative. I tried just hooking up the red lead to the pos. battery terminal - however, that didn't seem to work. It seems that something needs to be hooked up to the neg. terminal too. Someone help me please. I know if I can get past the ignition problemI can get this unit running. Thanks.
