Could it be a switch somewhere need love? Do you get any items popping up during the test mode?

check the batteries on the CPU board.
write the date on them and change them once a year.
if you are lucky the battery holder won't be corroded with leaking battery acid.

I'm with Tsj on this one..... I'd bet the bank it's the batts.... If it's still attached to the board cut the holder off and relocate the batts..

Batteries on cpu board, or a cold/cracked solider joint on the battery holder itself.
Anound 30 years of vibration/ heating and cooling of circuit boards = lots of wierd problems popping up. Hopefully the batteries didn't start to leak.

If you changed the batteries and the problem is still there, remove the cpu board from the backbox and check those solider joints around the battery box. It can really only be one or the other.

Usually the "adjustment failure" is due to batteries... Have you checked the battery holders themselves? Any signs of fatigue or anything?

It could also be a bad memory chip the batteries power and keep alive .. something I have not heard mentioned. I think this is U25 on that machine. It could be flaky.

If it's like alot of the Williams I have worked on it's a 5101 RAM IC. These are getting hard to find (obsolete) and go bad alot. You can still find them at places like Jameco Electronics. I bought a dozen myself last time.

Here is a link: Most of these are pulls off of old boards anymore.

Hate to pile on......but batteries .Batteries may be fine, but not circuit. My F-14 is that way as well. Previous owner had remote location.......the length of a cheap radio shack design. About 3 inches away from original. And it could also be what BD brought up.....I'll just shut up now!

That is a good point Twizz. Don't discount yourself. Could be any of these problems, or none of them.

Exactly .. we make intelligent guesses. But if you are gonna collect older Williams machines get a few 5101 RAM IC's while you still can.

I'll throw my hat in on batteries as well. Well, not batteries but the battery holder itself probably. Definitely go with a remote holder. It happens to all of them eventually I think. Good luck!

I like this for B/W games. It is quick, easy and non-permanent.

They are used in all the older Williams SS machines (system 3-7) to store high scores, system settings, etc ... the batteries keep it powered. It's an old obsolete memory chip that hasn't been made in over 20 years or more. So finding them is getting more difficult. I have some brand new ones but can only find used "pulls" anymore where they take them off old PCB's.

Go here and scroll down to section 3a for more info:

I believe they are also used in Gottlieb System 80 machines as well. Also Bally machines like Star Trek. Just a good thing to have a few of if you collect machines.

Help me out here others ... did I miss any ??

Mousin' Around is an 11B, does it still use 5101 RAM IC?

the batteries on a system 11 power a CMOS RAM Chip at U25 on the
MPU.
Part number: 5340-10139-00.
Part description is a 5517-2 2k x 8.

but first verify you have 5volts on the other side of D2 when the power is off.

I don't think so donjagra (only systems 3-7 Williams)
Here is the part number various manufacturers used for it:

# Williams: 5A-9017
# Bally: E-00620-0042
# Gottlieb: XO356

It is U25 on that machine but look above for info on that. It's Toshiba TC5517 and even harder to find. I think I've heard of people using a 6116 in it's place. It rarely goes bad.

Longspur-- Easiest and most productive check you can do is relocate the batteries. That's the FIRST thing I do on all my machines. If the board mounted holder shows signs of leakage REMOVE it, If not let it there.

Here's a link on how to do it and what causes the error you have.

ITS ALIVE!

Getting the "adjust failure" on my SOF
Lotta good info in this thread. I replaced batteries and managed to get to this screen, but cannot select yes for free play. Is my right black button faulty? Thanks in advance
20220710_112217 (resized).jpg

Start button changes the setting on most system 11 games.

DOH
THANK YOU!!
In defense of my dumb fuckin ass, this is my 1st System 11 and 1st problem in 2 years with it.
Thanks man!

This thread caught my eye.
Interesting how many inactive members in this thread.
And broke dad, retired pinside hero?
Old moderator?

I think he passed?
I think he was on here when I 1st joined and everyone seemed to love that guy.

Just to reiterate, to get OUT of the service menu, you just keep scrolling to the end? I got it playing but unsure how I actually got out of the adjustments...

Yes, you either have to go to the end, or go reverse till you pass 1 and onto the last number.
I think it's 72 for mousin.

THANK YOU GUYS!

I remember the name too. I lurked on pinside for 4 years before giving in and joining.

I just Googled "adjust failure" pinball and this thread was the 1st one to pop up.
Brokedad seemed extremely insightful and helpful too. I mean...look at his 3 posts...

This is all very strange, that game had NVRAM, should never need batteries… I wonder if the NVRAM failed.

I never bother the seller.

Ar least you weren't dealing with adjust failure in a foreign language like I am with my pinbot reiimport. I'm sure it's a battery issue but when I get it in English and factory reset it goes back to German or Dutch. I think a jumper has been added to the board to permanently convert it to a specific language. I'm not certain though, need to investigate further

Hey Doc if you need someone to go through the menu simultaneously I can try to help.

Are you sure brother? Looks like standard board battery placement to me. But again, I've only seen this System 11 bb

I guess so…. I meant to replace it before I sold it. I owe you a beer

Brokedad was a fountain of knowledge, but then some major drama. I think he was forced into retirement by the mods.

Well, as I feared, every boot up I have to clear the adjust failure. I can work around it to play, so atleast they made that possible.
Still want to properly fix.
Aint mad atcha Matt
I'll have that beer, and a NAVRAM thank you drive thru
20220711_201624 (resized).jpg

Hey man, one of your batteries is in backwards

Edit- maybe not. Looks like one is a different brand, I can't see the + end on those 2

Top right (-) battery connection is missing the contact and bakelite. NVRAM would be the best way to go!

I'll look for it thanks mang

Yeah Hunter S one is not like the others but I appreciate you anyway

Scavenged batteries

Measure the voltage coming from the battery pack. it certainly looks like a terminal is missing (probably corroded away).

A meter will tell you straight away.

That was actually one of my questions.
Looks like on the board they're all + facing down. Is this the correct battery placement?

correct

Seems like easy fix thanks folks

This is an awesome alternative to nvram and regular batteries.

I have one. I just forgot to open it last year.
