Sounds like the Palm Springs is really trying hard to work properly now again and maybe be time for a serious workout.
After you clean and manually check the odds unit and it is free up and working fine, then you might want to play the game for about an hour or more. It could be a good idea at this point in time, since the game is operating well now that you give it a serious workout.
By doing this hour or more serious workout you will get a better understanding on how, when and why the machine should be awarding a player features and odds etc. Getting a feel for how the machine is thinking mechanically internally will help with knowing if the game is working correctly or not. The more games you play the more you will notice what the machine is doing and thinking.
Spend sometime playing your bingo before trying to repair it...............?
An important part of owning your first bingo is getting comfortable on what the machine doing inside and knowing if it is right or not. The game has a mind of it own thanks to Don Hooker and you will need to know if it operating correctly.
Now that you cleaned your odds unit it could be time for a game workout and bonding with the machine.
Slide your playfield glass off and start a game. Next manually step up the odds to 64/200/300 and by hand place the balls into any 5 in a line winner allowing the machine to pay you off your 300 replays. Now your ready to give your bingo a good workout.
Start another game by pressing the red start button 50 times allowing the replay meter to move down from 300 credits to 250 credits. Every time you push the red start button, closely watch what features or odds are lighting up on the backglass. Take your time and move slowly when pressing off the 50 replays or credits observing the backglass features and odds and listening closely to the sounds of the mechanical parts operating inside the game.
Play (six) 50 credit games and repeat over again........by manually step up the odds once again to 64/200/300 and by hand place the balls into any 5 in a line winner allowing the machine to pay you off your 300 replays. Now your ready to give your bingo another good workout."
Play at least (two) 300 replay workouts while observing what is happening feature and odds and listening to the game mechanically to learn how the machine supposed to sound. This 600+ workout session should give you some important basic knowledge and learning and get your more inclined with the operation of these magnificent pin games.
Just remember these bingo type pinball machines were really built to be played non stop for hours and days at a time and need/love it too.
