My Bally knockout has been broken for 3 years I think it's time to fix it. The coil closet to the playfield on the bonus unit got stuck on and burnt out. I replaced it a few years ago and I got it to not stick on. But the outhole bonus does not work. The "bonus coil is buzzing a bit and when I manually actuate it it doesn't do anything. I am really lost when it comes to em troubleshooting. It's probably a stuck switch somewhere? Where should I start?
