Error Tracing - NDSolve

 Hi, 

is there any possibility in tracing an error in 
NDSolve ? 

I get the following message:

In[2]:=     sol =  NDSolve[ Union[equation, condini] , {y1,y2,y3} , {t, 0., 20.},
         MaxSteps -> 2000 ]
        
                                 1
Power::infy: Infinite expression -- encountered.
                                 0.

.... and unfortunately, the system seems to be well defined. 

 Thanks,

  a + andrei

PS I can send the entire file if there is a more precise interest
in the question.
