2003 Bombardier DS 50 lost spark
 

We have a 2003 Bombardier DS 50. We were out riding one day and everything was fine. Got the quad out the next day and it wouldnt start. Turned out it had no spark. I checked all the wires and the kill switch and even disconnected the killswitch but could not get a spark. I ordered and replaced the CDI and still no spark. I am at a total loss here. Does anyone know what may be wrong?
