I was prepping the electronics for the next flight of my rocket yesterday, and when I attached the igniter to the electronics terminal... POOF!!! The igniter fired. Needless to say, something was malfunctioning. I checked th manual, and one thing I saw was that if you switch the battery polarity it would result in the immediate firing of any attached igniters. So I checked and triple-checked the terminals, and they were definately in the right order. So I have a puzzle on my hands.
This was a very dangerous situation. Had I stuck the igniter into the motor first, a G71 would have fired in my bedroom!
Things will probably work out, however, because the launch for today got postponed because of rain and thunderstorms, so that gives me time to order new electronics.
