Quoted from chubtoad13:I must’ve worded my question weird. I meant to ask if there’s a benefit to switching if the original board works.
My bad. Thanks for the replies.
I guess the only benefit would be a higher likelihood that you won't experience a failure due to aged or fatigued components.
Hey folks… have a new meteor that’s set to 5 ball. How are the dip switches ordered on the cpu board? I see one bank positioned horizontally in the middle of the board, and three banks vertical on the right side…
Quoted from La4s:Sounds like you either have the AllTek or Nvram.Weebly board. There should be 4 banks of dip switches veritcally on the right of the board. You want to change switch marked 7 to OFF.
The single dip in the middle of the board is for selecting the game ROM.

Yes, it’s NVRAm… it’s just that all of the dip switch banks have a 7 in them.
Here’s what mine looks like. Not sure up from down here. Hoping a Meteor junkie can give them all a quick peek and see if anything is out of sorts… but mainly wanting to get this puppy on 3 ball

Thank you!
Need a little tech help on Big Game.
Yesterday, was playing a game and the right flippers went unresponsive, then came back online, and then permanetly stopped working.
So far, I've inspected for broken wires around the flippers (can't find any), confirmed the leaf switch at the flipper button is making contact and is clean. Checked fuses on the rectifier board... and gave boards in the back of the game a visual inspection.
Is there a bank of fuses I'm missing?
Thoughts?
I own two classic sterns, but really haven't needed to dig too deep, tech-wise. So, a little green here
Quoted from DudeRegular:Check voltages would be where I would start.
Off rectifier board, correct?
Quoted from cottonm4:Since both flippers are not working that suggests the flippers are OK. Try a jumper wire from the yellow power wire on any other solenoid to the power lug on your right flippers and see if that helps.
or
Desolder the orange and green trigger wires from both sets of flippers and jumper criss-cross the orange and green wires and see if the problem follows the jumped wires.
and maybe....(this one is circuit board and I am at a loss) but maybe something happened with your SDU. Since you own two classic Sterns you could swap in the SDU from the other Stern and isolate the SDU that way.
I follow the first suggestion... not the second.
The Driver board is new, so, hopefully that's not it!
Quoted from Mad_Dog_Coin_Op:Did you check the fuse between the flippers on the bottom of the playfield? Sometimes the easy stuff gets overlooked.
The left flippers are working, so I’m assuming that’s not it.
Update. Got it all sorted.
Ended up being a cold solder joint on one of the flipper coil legs. Discovered following confirming power at the coil, and @dotheedo's suggestion of "start a game, hold in the flipper button and lift the lower flipper by hand (assuming that’s the one with the double EOS switch). If that triggers the upper flipper, then your problem is with the double EOS switch or the lower flipper coil."
That worked... and isolated the issue to the coil with the double EOS switch. After wiggling some wires with the flipper button depressed, it became evident there was a solder problem. After some flux, a little reflow... she's back and firing on all cylinders.
Thank you, all, for all of the tech help! Despite being in the hobby for 10 years, it's awesome to get community support.
So, next question.
I have Big Game and Meteor. REALLY really like both of these games.
What's next??? 
Quoted from snyper2099:I mean questions like these don’t really matter. One game is not better than the other. Nothing is accomplished or gained by asking or answering such questions.
Just sparking conversation… not looking for some definitive answer. no need to rain on the parade!
Quoted from DanMarino:Didn't Harry Williams also design Flight 2000? Such a good game with a challenging to earn multi-ball.
Yup. It’s a good one, for sure!
Quoted from Mathazar:Give this video a watch - it set me on the right path when I first got into re-pinning Molex connectors.
Holy f***… that guy’s fingernails need some sanitation!!
Stumped…
Right flippers on my Big Game are out again. They were working, then started to rapidly pulse when the flipper button was activated. Then they died.
Few days later, they were working again, then started to rapidly pulse. No dead.
Reflowed solder. Got no result…
Ideas?
Quoted from play_pinball:27dnast how are the contacts on your flipper button switches, on the cabinet?
I think they’re good to go, but will clean
