Hi all, During a recent run of my 3" coil the line filter did some odd things. First it made a popping sound then shot out a 3" flame until I shut it off. The flame came out directly under one of the output posts. Any idea why this happened? Coil Specs: 12kv 60ma neon 120v pri 3" x 10" sec wire primary .008uf cap RQ gap max arc: 20" The line filter was rated at 20A 240v
