I bought a wells auto ignition coil at Auto Zone, so I don't think they're
out of business. That was just a couple weeks ago and it was for a DC tesla
coil as well. Are tw auto ignition coils reall nessaccary? Mine runs with
one and uses a 12V SPDT relay to pulse the current. It's the first coil I've
built, and so far it's been runnint fine. Sometimes I need to give the relay
a tap to get it to start running. Good luck.
