I will be the first to admit that I dont know much about ATVs. I am working on my bosses atv and it will crank but will not start. It cranks but no spark. I found that the wires on the ststor were melted off so replaced stator. Still no start. Since then we have replaced regulater and ignition coil module. Still nothing. We checked the kill switch and found corrosion at the plug in. Replaced switch this morning. Still no start. Found it will start if I disconnect the black wire from kill switch to coil. As I dont have any manuals to look at I am totally lost. Can someone please point me in a direction to look?. Thank you in advance.
