I pulled our board apart and this is what I found. On CB1 the trace that goes from Q5 to R9 was broken away from the board and folded over. I do not know how this could have happened unless it happened as a factory defect. This board was purchased fall of 2010 and installed as a retrofit to our 2007 machine as a fall training project. This board has never seen competition play and has been sitting dormant since Fall of 2010. I'm thinking this trace was already broken and since it was part of a retrofit of a machine that never really saw much action once the retrofit was complete, we never saw this problem.

My confusion lies in that if this circuit is isolated why would it affect the rest of board when we saw high current draw on another breaker.
