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.

here . . .
