         You're changing the topic (enamel
scratches) but I disconnect my Beverage
wires with relays when lighting is near.
I've never lost a transformer although
I've had both small reed relays and the
termination resistors completely explode.
I open circuit very small reed relays for this
purpose precisely because they cannot
handle high current and act as fuses
ahead of the transformer itself.  Probably
also a good reason to use small interconnect
wire (e.g. #30).

         My question was about checking
for shorts immediately after winding using
an analyzer.  The same technique would
apply to checking for lightning damage
before opening the enclosure.
