Hey guys new on here and looking for a little help. I have a 220 bayou early one (not a three phase stator). I don't have any spark and when I got it it supposedly had a new cdi box and a new ignition coil. I have good voltage from the source coil, the ohms on the trigger were a little low but it picked up voltage on my multi meter. My question is am I supposed to have a 12v power wire at the box or is it just getting power from the source coil. In other words what is the yellow red wire at the box. Any help is greatly appreciated.
