Noticed an odd problem while playing last night. Was in the middle of a monster game (of course), had all passengers picked up, and hit the lit "carry passengers target" (Yes!), ball came firing back and hit the slings back and forth and then rocketed down the out lane. I plunge the next ball, and suddenly I notice that the gorbie shot keeps getting rejected? I continue playing, and also notice the slings aren't firing either (when they were before). I pull the glass and hit the wireform gate switch that opens the gorbie gate temporarily, and nothing. Slings not firing when I trigger them with a finger. Carry passengers switch not registering when activated, but the pops ARE working when triggered (they're all in the same switch column).
I put the game into switch test mode, and none of the switches in the column were registering, but the associated coils all fired in coil test. I look under the playfield for a broken wire, and can't find anything. I then pull the switch matrix connector off the board, reseat it, and no change when the game is powered back on. I power the game off again, pull the connector back off, and punch the associated colored wire firmly back into the connector with a jeweler's screwdriver. I power the game, and get a message saying "Factory Restored" or something like that, and everything in the column is now working correctly in edge test and in actual game play. I had to reconfigure the setting to freeplay, and I lost my high scores.
I never touched the remote battery pack (yeah yeah, I know, at least it's off the board), so I'm not sure what would have caused the factory restore? Anybody ever see this happen before? Admittedly, the batteries in the pack are old and the ones that came in the game when I got it a couple months ago (I'll swap them to lithiums this evening). Is this purely coincidental? Can the batteries being dead or low cause a switch column to go out? The whole thing is very strange...
