PK, I'm sorry you had the trouble, and I'm even more sorry you didn't let me know about it. I've had extremely few failures over the nine years I've been making ignition units, and would still be happy to send you a replacement or replacements. If you email me to remind me of what you have, I'll be happy to get it/them on the way.

Sending the failed unit back to me would be helpful, since I might be able to determine what failed.
