Buly,

Sorry for the brevity. "NO" is for Normally Open, "NC" is for Normally Closed. The injector relay has an "NO" terminal which the contacts are open when unenergized, and an "NC" terminal which is closed when unenergized. When Tracy did the snubber upagrade, he instructed me that the wire connected to the NO (or NC) terminal needed to be switched from how it was before the snubber upgrade. Sorry, I don't remember which one is the correct one. Check the schematic furnished with the new manual. (Not the one showing only the injector circuit as it is incorrect. Use the more detailed one towards the back of the manual, it is correct.)

If I can find his NO vs. NC email, I'll repost it.

Tracy did not mention it, and my unit is from 2002. What is NO
terminal? I'll check the schematic tomorrow if I have time to get to
the airport?
Thanks Mark.
