I have a 2004.5 polaris sportsman 700 with no spark, it has the polaris factory DC ignition system fix, but I found A big crack in the cdi box so I’m going to start with that. I found a cdi box on line for a 2004 polaris sportsman "600" and was wondering if it will work, is it the same as the one for the 700? Looks exactly the same as my cracked one in pictures except it came off of a 600? Please help me.
