I have a few segments out on the display of my Whirlwind. I pushed the Advance button to begin the test and something strange happened. The coil for the left slingshot began firing, about twice a second continuously. I was unable to back out of it so had to turn the game off to make it stop. I have no idea where to begin looking for the solution to this. Any ideas? It should be said that I am a novice at pinball repair...

zacaj That was totally it. I'm a dummy. Thanks for your help.
