============================================
Mark,

The self destruct fire item is the only reason that I see to go beyond
interrupting the B lead.

Interesting my ND alterator does shut down when I shut the power field
off and it is internally regulated. I thought that was normal, but there
were potential internal failures that could trigger the runaway
alternator and then I would not be able to shut it down. Is that confused
thinking or why am I able to shut it down while running?
