Bill, Terry, all,
It is also interesting that static gaps often stop firing for awhile (when
the total gap spacing is wide) and
then start up again, by themselves. I would think that if they are firing
at a reduced voltage as they heat, then they would not tend to stop
firing once they start, yet they do. Another mystery.
