I obviously don't know what your kit looks like, so I'm kind of guessing here...
If the cases on your ballasts are made of metal (the McCulloch kit is), you can try connecting a suitable size wire between the case and a good grounding point to see if it make any difference. You could also look at getting a pair of noise suppressors from an auto supply haus and installing them on the power leads to your ballasts.
One thing is for sure. The Crossfire has something like 5 computers on it and computers like nice clean power or they can become very unhappy. It would be in everyone's best interest to find and eliminate the source of the noise.
