I have a go cart with a 110cc chinese engine on it. It's the same engine that is used on the atvs. I am not getting fire to the coil. I have replaced the cdi box and checked all of the wires. I'm getting power from the stator ignition and timing wires but there is no power coming out of the cdi to the coil. The new cdi box i got has an led light that does not light up. Could it be the new cdi is bad or is there another problem?
