Powered Antenna? Maybe when you hit those things it flips out?
That's really a interesting situation you got there. Like the old TV shows where they turn on the faucet and the water comes out the stove!
If you have one of those powered antenna amplifiers, see if you can notice if the light flickers when you hit the igniter. I'll bet Norty1 is on to something there. Some kind of electrical interference. Hope you figure it out and I can't wait to see the answer!
