I have a 500CC Chinese ATV which is a 2007, I have had it for around a year now and bought it off someone down the road. Just about a week ago, I took the rear fender off to clean it and to use some engine shine. But I did use quite a lot of engine shine. And I then put the entire fender back onto the ATV, and when pulling the battery wires into the battery box I was pulling on the wires. And then I attemped to start the ATV. It will crank but that's about it. I tested the spark plug, and it turns out there is no spark. So I replaced the spark plug with a new one I ordered a new spark plug tested that one, still no spark. I then tested the ignition coil with a multimeter and it is reading that there is no power getting to the ignition coil. I am completly lost with this!!! Any help is better then no help!! I have the owners manual and the wiring diagrams if needed. Thanks,

Well if it ran until you were pulling the wires back to the battery box then their lies your problem. You have probably broke a main power wire to computer or jiggled the fuse loose. Start following your power wires. One will go to starter and one will go to computer or fuse box.
