I finally got a Big Guns and can officially join the club! I'm having plenty of issues with both cannons, ball poppers, and the VUK. The right ball popper sends the ball into the right cannon, but that's all it does. The cannon never fires the ball. Same with the VUK in the back. Ball will go into it and will never be sent up. The left ball popper never loads the ball into the left cannon. During multiball, none of the cannons fire and the VUK never works. I've checked every single fuse and reseated every connector. The switch test shows that every switch is being activated that is having a problem. Doing a coil test never fires any of the coils that are having problems. What should I check next?
