UPDATE- This problem mysteriously resolved itself once. It started acting up again 8/16.
I got my first pin, Space Invaders, several weeks ago. After replacing some bulbs and fuses it is (was) fully working. Now I have this weird problem.
My thumper bumpers and slingshots seem to effect one another and I cannot figure out what changed or went wrong. Here's a rundown of all the problems that popped up at the exact same time.
-Left bumper triggers right bumper and left slingshot, but not itself.
-Lower bumper completely dead.
-Right bumper triggers self as it should.
-Left slingshot triggers self, but also triggered by left bumper.
-Right slingshot doesn't trigger at all, but it still scores.
-My right drop target doesn't reset.
-My ball kickout doesn't kickout anymore.
All the above symptoms appeared at the same time. Everything worked fine one night and went bad the next time I turned the game on.
So far I checked all the voltages on the rectifier board and they are good. I've also looked for obvious crossed wires and found none.
I'd appreciate any help you guys can give this pinball newbie. Thanks!
