Newb here, having a weird problem with my gun. When I start it up, it usually plays fine for a few games, but then the gun won’t stop rotating back and forth and the game won’t use it anymore. The weird part is, other aspects of the game change too after the malfunction- it auto plunges, the ball save gets very generous, and if you start any of the hurry ups the timer doesn’t count down. Disabling the gun in the settings makes the other issues stop. After the malfunction there’s a credit dot and the test message says “gun broken.” Before the malfunction there’s no credit dot.
Another time after the malfunction, the test message said to check switches 44 (gun chamber), 45 (gun popper), 76 (gun position), and 77 (gun lockup). When I run a test on each individual switch, 45 is closed and displays an (A), while the other three are open. I'm not sure what any of that means. There is also a gun test, but that looks like it's just testing whether the gun will move and rotate properly, which it does.
Any suggestions- especially bearing in mind that I know almost nothing about pinball repair, tools, etc. I'm trying to learn as much as I can and have learned quite a bit in the past couple of weeks, but am still getting started. So, idiot-proof explanations would be appreciated. Thanks!
