I have done emergency repairs several times with good success. Just unwind
damaged turns + few turns and scrape at least most of the black stuff off.
Then connect the wire by soldering and make sure the joint is as smooth and
as close to wire diameter as possible. Finish the job by brushing some 5
minute epoxy over the damaged area and the coil is good to go again.
Tesla coil secondaries are surprisingly tough, i had one small drsstc which
had 4 or 5 repair spots due to trying to beat 5x secondary length spark
record.
