Sparking off the secondary problem

Hi, I finally got my Tesla coil working.  It was going good (about 2
foot sparks) Until I took the toroid off to try just a aluminum pan.
This worked, but not well. anyway, I put the dryer duct back, and
instead of working normally, it shot sparks 2/3 of the way up the
secondary, and smoke (nothing from the toroid).  I turned it off,
checked the connection between secondary and toroid, and tried again,
same problem.  Any ideas?  Is my secondary ruined?  It measures 55 ohms
from ground to toroid still.  I'm afraid to turn it on.
Thanks.
