You should definitely coat the secondary with 3-5 coats of (non-flammable) varnish. That helps reduce corona loss on the secondary. I would start there.

after doing some more research online, i found out that my coil is over coupled. i will just have to adjust the hight when i have some free time. thanks for the tip derstrom8. i have at least 10 coats of enamel coating on it
Over-coupling makes it arc from the bottom of the secondary to the primary (or vice versa). I don't think it would make it arc from higher up on the secondary. Have you looked at where the coil is arcing from? Are there any obvious blemishes on the secondary, like bumps in the wire (or kinks) or scratched insulation? That could also cause the problem.

Go ahead and lift the coil, but check the secondary first. You might find something that you didn't know about ;)

Good luck!
