Bob,

curiously enough mine's a Europa too.  Could it be something to do with composites?

  no . . it would have happened in an RV too

Another Symptom which might help the discussion.  The CB tripped ONLY at the moment of switching off the ALT.  It could be reset immediately after with no ill effects suggesting that it was something to do with the switching off itself that caused the CB to trip.

  Yup . . . that's how the transient event is
  created.

  When the controlling switch opens, the magnetic field
  in the relay collapse very rapidly (~3 milliSeconds
  in the plot above).

By the way you all have completely lost me on the technical stuff - but I am reading with interest,

  No problem . . . that's what the List is for. Advise

  nobody is going to blow smoke blown up your pant leg
  here . . .

Bob:
With the screen shot of the O scope...  
What signal did you use to trigger the scope (capture the screen shot)?
The 'M'...  Is that for Manual Mode?
Where do you have the leads attached?
Where are you measuring the ~3 ms from & to?
What is your definition of: "Fire across contacts" and Fire goes out here"?
