Hi, I have heard that it's a good idea to remove the green battery. I have a few questions before I start:
How do you remove the MPU board safely?
How do you reseat the MPU board so that it won't break the board in the back?
What tools do you use if you don't have a soldering iron to remove the battery?
What type surface is the best to set to set the MPU on if you don't have a grounder? ( Wood, steel, on the wooden floor, tile...)
How do you handle the board iF you don't have a grounder? Or how do you ground yourself while handing the board such as walking with it to the work bench?
Thank you :)

The steps necessary to remove the green battery depend on the mpu type you have. If you have a 500 series board, you can just remove the battery. If you have an enhanced board, you have to also remove the regulator at position U16.
The mpu is on a tray, you do not need to remove the mpu board from it's tray in order to remove the battery and the regulator if needed.
To remove battery without a soldering iron, you can use some cutters to cut at the base of the pads that the battery is attached to. One side has two pegs and the other side has one peg. Just carefully cut them at the base and you should be good. A lot of us find it easier to cut the single peg, then bend the battery to easily expose the dual pegs.
Since the mpu is on a tray, just carry the tray without touching the components over to where you are going to do the procedure. Set the tray down, and ground yourself by either touching the bare floor with you feet (without socks or shoes) or your hand on something that is grounded and you should be good to go. Try doing it somewhere where there is no carpet to build up static.

Thank you so much for your help, what kind of cutters do you use? I have a set that are really thick for cutting metal earring posts since I make origami earrings for strores, Could you possibly send a pic of the cutters you use so that I can ensure I have the right kind? Thank you
-
Like a cuticle cutters in size, but for metal. Actually, if you have one, a cuticle cutters would probably work fine
-
Thank you, I'll ask to see if my sisters have a cuticle cutter or not, they like to do nails a lot
-
My sisters don't have any cuticle cutters at all , but I did find these clippers in my origami supplies ( see pic below ), Will these work or not? They seem a little thick around the heads
-
If it is a 500 series board and all you are doing is removing the green battery just gently rock it side until it snaps off.
If you are trying to cut the regulator chip off of a 1270 board those cutters are a little too big and clumsy
-
Same deal though, just rock the U16 transistor back and forth till the legs break
-

Those diagonal cutters may be too big for this job. You don't want to damage the board or nearby parts on the board. Your machine is working, be cautious doing this mod. It's not a difficult mod, but be careful.
Nice nails! :garfield:
-
Thank you, my sister's friend painted my nails over Labor Day weekend :) What is the mod that your talking about, I'm a little confused? And I'll look for smaller clippers
-
I also feel a little nervous about removing the MPU tray from it's seat inside the machine, How hard do you have to pull?
I tried pulling it out last night ( with the power off ) but it wouldn't budge, Then I powered the machine on and it still worked ( which is good )
And how hard do you have to push to re-seat the MPU while keeping the circuit board on the back of the machine safe?
-
It takes a little effort to pull it out. It is held there only by friction from the connectors. It is unlikely to damage anything other than you hand if it comes out really fast and you happen to jam your hand against something. I've killed my hand many times pulling things out machines before, so just be careful. To re-insert the mpu, just keep pushing with a little force until it no longer moves. You can sort of tell when it is in. The backplane its pretty safe, you are unlikely to do damage if you push just the mpu in.
-
Thank you so much for your advice :) I'll check the MPU when I get home to see if I have a 500 or 1270
-
1270 has a wire handle you pull on to remove, 50x has just a metal angle to grab.
-
Mine appears to be a 500 because the photos I have of the tray still in the machine show the metal angle that you described.
(edit to fix sideways photo)
-
Yeah, that's a 500 series. Just remove the green varta battery if it's still there and check for/clean up any acid leakage. Be sure to remove the coin tray before removing the MPU
-

I meant this mod (modification) of removing the green battery and the u16 part if needed to be removed.
-
Thanks for the clarification, I am wondering what you use to clean acid from the MPU circuit board?
-
It's actually alkali, the battery is (NiMh) and the area needs to be cleaned with a mild acid solution made of vinegar and water to neutralize the affect. Then use clear water and dry completely before reinstalling. Q-tips dipped in the vinegar solution and rubbed on the board and components followed by the same procedure with just plain water a few times.

Yes - what qbert said.
If a battery has liquid inside, like your car battery, then it is a "wet" cell battery and has acid (usually about 50% sulfuric acid and 50% distilled water). If the battery is dry inside or has thick chemical paste then it is usually an alkaline substance. Both acid and alkali are very corrosive to metal. That's why when it leaks it can eat thru the copper board traces and the legs on ic's. Or destroy your old-style flashlight. An exception to this are the lithium batteries, they are dry cell but generally don't leak and cause problems.
Since people are so familiar with car batteries and they hear about them having battery acid inside that's probably why there is the general impression that all batteries contain acid. Around here some stores that sell auto & truck batteries used to wait until someone bought the battery, then they would add the battery acid and charge them up. And people used to rejunenate weak car and truck batteries by adding a little sulfuric acid.
-
Thank you so much :) I'll do that if the board needs claanjnc
-
White vinegar.

Removed the MPU to get a photo, Double checking, is this a 500? And now I'm not sure what to do because I re-seated the MPU and started up the machine and now I have a reel 3 tilt
-
And I think that I accidentally touched the back plane board with the tip my finger nail while holding my phone when I was trying to get a photo, Will this do any damage?
Edit: Both my feet were touching the ground and my phone was unplugged. Before I moved the MPU I touched the metal cabinet door for 20 second and my floor is a wooden floor

With the amount of humidity we have in the air during the summer time it is not all that likely you can cause static damage to electronics with what you are doing. Unless you really try, like shuffling your feet on carpet, petting your cat several times or rubbing your hand vigorously on the dry hair on somebody's head, you will have a hard time building up very much static elec on your body. In the winter time when the air is drier, especially indoors with heating furnaces running making the indoor air extra dry then you can make static elec on your body much easier. The large repair shop I worked in had big humidifiers that ran all the time during winter, they kept the indoor humidity at 50%. The quality dept checked and kept a log of the daily humidity readings where we handled electronics.
With the machine plugged in to the wall outlet the metal chassis is grounded to your home's elec grounding wires, if you have a 3 prong outlet. That's what that 3rd prong, the longer one, is for on a power cord. So touching the machine metal surface should remove any static charge you have on your body. This doesn't mean you shouldn't be cautious when handling circuit boards, but don't overly worry about it.

Thank you, I live in the west where it's really dry now and I hope that my slot machine will be okay
-
What part of the west?
-
Midwest, around New Mexico and Colorado
-
You'll be fine, just try to keep it under 100
-
Thank you, What does keep it under 100 mean?
-
Degrees in the room where it's kept
-
Ok, my slot machine is kept in my living room and it tends to stay in the 70's ( Blasts disco music in the room )

Long live the music of ABBA ! :garfield:
-
I don't think I've heard of ABBA before, I imagine they must have had some really good dance music :wav: :wav: :wav:
-
Mama Mia, movie that uses the ABBA song as it's theme song
-
Now I remembered, I'll be singing MAMA MIA all day long, "Moma Mia, Moma Mai, Moma Mia"
-
Just thought of this, What could be potential errors from removing there green battery and how would you resolve these errors?
-
There shouldn't be any. Changing the cmos battery trips some ram errors
-
Thanks and what does the cmos battery look like and do?
-
The coin battery that retains ram memory
-
Thanks, that makes sense now :)
-
The green battery is strictly there to let the casino know if the game gets messed with while it's turned off. It powers telltale alarms connected to the casino computer system
-
That makes sense, I didn't know that the telltale alarm was connected to the casino's computer system, I thought it would set an alarm off within the machine if someone tampered with the machine with the power off
-
That would take a much bigger battery
-
No real alarms. The green battery allows the machine to hold in it's memory "time stamps" of what and when something was done to the machine when the power is off.
Things it records: time and date when the main door was opened, same for cash box door, cash box removal, etc.
In that way the casinos could go back to their camera systems for those times and find out who was there. All of that type of data really is useless for the home owner, and we know the batteries leak and ruin hardware, that is why we recommend removing them. I do not agree with " keeping the machine as close to how it was in the casino" The machines are for enjoyment and in the end I would much rather have a functional machine the a non working one that you can say is "Just like it was in the casino " That's crap especially if you install a TITO system, those were never in the casinos either but if you want the "casino ticket in" feel you install them.
For me I want my machines functional for as long as possible and removal of that nasty green battery is the first thing a home user should do.
-
I agree with you and that green battery is so useless for a machine that sits in my house, I don't plan on installing a TITO system because they seem like a lot of work due to needing to get new printer ink and paper
-
No ink, the tickets are thermal paper. TITO is a good addition and if you get one for each machine the ticket from one will work with in the other.
Now get on with it take that battery off!
-
That is so cool, I didn't know that I thought it was ink based all along :o And I'll get the battery out :)
-
Guess what? I removed the green battery :)
-
Good job! As far as TITO goes, it's rather simple to install, just requires a working printer, bill validator and clear/key chipset. Look at bettor tito sold from bettor slots listed on the homepage. Personally I don't give a crap about redeeming tickets, I like the ability to add a hundred credits by pushing the service button on the player panel. There are lots more options available also, like adding credits and controlling other features from your phone or computer
-
Thanks, I may consider one someday and I want to thank everyone who has helped me removed the green battery <3 All of your help has been very appreciated :) And it's such a great feeling to have that battery out of there
