Mine is a Lamar unit and it was pulled and bench tested (after a 'jump start' followed by losing electrical in flight). The alternator passed but as I said the 40amp breaker got fried so I could not reset the Alt bus after total electrical failure.

Is it a 40 amp alternator? 42 Amp? What is the breaker protecting? If the battery was dead and the alternator was going full tilt to charge it, plus the electrical loads, it is possible it was putting out greater than 40 amps. If the breaker is upstream of the battery, the breaker may have been right on the edge of tripping for a while and melted instead of opening. Take a hard look at the alternator/battery circuit design as well as the alternator sizing.
