Electrical Short Blowing CDI

I have read about people having electrical short issues that tend to blow a CDI. I worry about that with my sled. I have had two CDI's go out on me during a ride. Where would I look? I have just recently replaced the Stator thinking that this would most likely be the root of the problem. Are there other places that I should look before putting another CDI in this machine? Thoughts on how to narrow that down?

Also, is there anywhere to go to get a CDI rebuilt?
