About 6 months ago, the ball eject system increased in force. It really pops out! Now with push of start button, the ball pops out and there is a sharp thud or clank in lower right hand corner of cabinet and Thor target fires with multiple points given without a ball being launched. During 1st ball launch and play, there are multiple times the game automatically goes into various Avenger vs. Avenger modes, even without them being collected.
I went through all tests and diagnostics. Everything is find except for a switch alert: D-15: shooter lane; "out of service." There are FIVE switches under the ball trough. All solder joints appear intact. Can I assume it's one of the switches? How do you test them? Do you use a volt meter and if so how do you test them? I'm not an electrical whiz!
