Time to start troubleshooting. Sounds like the NST to me. It's possible one
damaged. See if you can draw an arc from both sides. The gap is easy, just
segments. Another possibility could be a shorted winding on the secondary
burn spot where two or more windings short together - sometimes at higher
entire shorted turn will burn all the way around). My hunch however is the
check wiring - run it with lights out and look for arcing). Just start
