Hello all,

I am new to the forum. My 9 year old son saved up his birthday money and bought himself a Baja 90 ATV. I had to replace the carburetor and after this it ran great, for a couple weeks. Now it does not have spark. The black with yellow stripe wire going to the coil has around 7 volts while cranking but only when it is disconnected. When it is connected it reads 0 volts. I have searched the forum and read all of the threads regarding no spark in these quads but none cover my specific issue. Any ideas?
