Yuri,
My guess is the coil is not tuned. If you're just using one leyden jar,
that's probably not enough capacitance. You may need 30 jars depending
on their size (capacitance). The primary has to be tuned to the same
frequency as the secondary. You can add turns to the primary to reduce
the number of leyden jars needed.
