Error Tracing - NDSolve

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 ]
Power::infy: Infinite expression -- encountered.

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

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