Greetings,
Recently, after replacing the battery on the mother board, a nice person here helped me with using the reset button behind the power switch and the master key in getting the error code cleared and machine operating again. A few weeks later it just quit. Pressing/holding the reset button does nothing. Turning the reset key does nothing. Play arm locked. No lights or displays except the three florescent bulbs behind the glass. I did check the three fuses to the right of the coin hopper.
While making sure everything was seated, mother board, coin hopper, etc. I did notice the comparator wasn't seated. Looking closer I could see the clips were broken.
So, number one, is there someplace I can purchase the clips that hold the comparator? Then, could that be why the machine is apparently dead?
Thanks, again.

I would start by checking to make sure you got your MPU board seated all the way down on the connectors on the mother board. As for you comparitor clips you could post a WTB ad here for them or try contacting any of the venders located on the home page. I have seen them for sale on EBay too.
-
I did try re-seating the board and feel it is inserted correctly. I appears to fit snugly all the way around. The unit worked for a a couple weeks after replacing the battery.
-
Apologies for being ignorant . . . found the WTB/WTS sections but I don't see how to post. The "new topic" button doesn't appear for me. What am I doing wrong?

Unfortunately that option is only available for contributing members.

$20 sent. Small price to pay for the help.

Thank you for supporting the NLG website. :cool_thumb_up:
Your WTB request for coin comparitor clips has been moved to the Classified Ads area. Hopefully someone with those parts will contact you.

Discussion regarding your other questions can continue here in this thread. Thank you!

Thank you.
If the comparator isn't seated properly would that cause the slot to appear "dead" as noted at the beginning of this string?

.....If the comparator isn't seated properly would that cause the slot to appear "dead" as noted at the beginning of this string?
I don't think so. The clips just hold the comparitor in place so that the inserted coin drops in properly at the top and then drops thru the coin optic boards below. The wiring harness that attaches to the side of the comparitor has a ground wire. I'm not expert on S+, so let's hear what others say.
Did the coin comparitor work ok at one time? If so it is probably still ok.
Your problem description sounds like a power supply problem. Maybe the power supply connector on the motherboard is acting intermittent. This is a known issue on S+. Examine the power supply white connector that connects to the motherboard. Wiggle it while the machine is powered on, see if the reels or other stuff starts working. Look for darkened or burned places on the white connector.
Post a photo of your motherboard, we may be able to see something that could be causing the problem.
-
If I unplug or plug it back in there is a very momentary audio click and the wheels barely tick. Jiggling doesn't do anything. So now what? Replace the plug?
-
And yes, the comparator was working after I replaced the battery.
-
Don't replace the motherboard power supply connector just yet. It may be ok. With the machine power on if you try to move the reels by hand (gently) do they have a stiffness to being rotated? If so that means they are getting power.
Can you post a photo of the motherboard connector? It is hard to give advice without seeing what you have there.
Are all 3 fuses still good, and do all the fuse caps fit snugly?
Any chance your machine has been underwater sometime in the past? If so that can really mess up connectors.
-
The machine has been sitting where it is for several years. No water. The connector has a brown spot on the back as in your picture. Wheels were loose. So I pulled up on the connector until the wheels firmed up. Closed the door. Bingo. Thank you. So, should I replace the connector?

Definitely. Or you can just replace the electrical contacts inside the white Molex housing. Good job!
I think there are folks here that sell that power supply harness if you want to just replace the whole thing.
-
Also may need to clean the motherboard male pins that mate with this white connector. The corresponding pin may have a bad place on it.
-
That's easier said than done! LOL. I don't have the right tools. I remember replacing a similar pin on a Magnavox turntable that had come unsoldered. I think I used a toothpick and something like an ice pick to get it out. That was on my counter top. I'm not so sure that would be do easy with my head in the slot machine. LOL
-
If you pull the mpu board out of the machine like you did when you replaced the battery you can then remove the motherboard. With it out of the machine you can more easily clean any male pin that has a burned place. Can use a soft eraser or maybe some light sand paper that is folded.
Once those pins & sockets (male & female contacts) get a bad spot it can happen again. A lot of amps goes thru them. The surface of the electrical contacts gets overheated because the connection isn't tight or gets corroded. Once the point of contact gets in that condition it just keeps getting warmer and warmer. And that reduces the electricity that gets thru the connection so your machine isn't getting the power it needs.
-
Your old pins in that plug only contacted 1 side of the contact. Getting a new plug will have 3 sides making contact. Much better. Most people sell them for around $15.

.....That's easier said than done!.... I'm not so sure that would be do easy with my head in the slot machine. LOL
You might be able to get a volunteer to help! :garfield:
-
Lort!
-
send those volunteers this way :I_agree_1:

It looks like that cable is short and goes over to the power supply. Can the cable just be replaced?
-
yes, I think that little wiring harness can be replaced, that's what I meant in reply#14. It should be available online or here on NLG from some of the parts sellers.
-
Ah, cool. What do I call it? LOL
-
We can post your photo of the bad motherboard power supply connector and ask if anyone has a replacement wiring harness/cable. That might get a response. Can you see the other end of the cable, does it unplug, or does it go inside the power supply?
Also, since you are in contact with Spin, inc you can ask them about that cable to see if they have it. Not everything they have is listed on their website.

Ken/Chris have new ones:

I placed a WTB request for you just in case someone has a spare cable from a parted-out machine.

And as Mark said, Ohio Gaming has new ones and you can't go wrong when dealing with them.
