Thanks everyone for the advice. I still get no digital display unless I hold the little white button on the coin meter. After checking the coin box door I found the switch jumpered and bare wires touching the metal, Fixed that and did the ram clear with the hopper in. There was never a ding after pressing the test switch. After closing and latching the door I turned the Jackpot key and reel cycled after a moment. Put the right chip back. Still not working right. No display, it will show 0 credit if press the service credit button but goes out. I think this is progress and will probably do another ram clear. I attached a better photo of the board in the top of the case and 1 of the last error I had.

[Stayouttadabunker]

Put that Clear chip away....you're only causing MORE PROBLEMS with it.
It fixes nothing right now.

[62-1] means you need to turn off the power switch, remove the MPU  and check the pins on the Reel PROM.
You probably have a folded, bent leg under the chip body.
Take a close up photo of the reel chip in it's socket.

That green board in your photo is nothing that you will ever use.
It's a switch for a Bally player tracking system.

Greetings,
 I put the clear chip away and checked both chips. Everything looks good under magnification.

Power on:
No beeps, nothing from BV, Reels lock, and denom is lit.

Press test button by power switch once:
 No beeps, Bet 1 credit button lights up. Nothing else. Wait a moment then press test button again. Pull handle solenoid releases and Spin Reels button lights up.

Close door:
Both buttons lights go off, Reels cycle and stop from right to left.
Insert Coin display is on.

Turn Jackpot key once:
Pull handle released, Bet 1 credit and Spin Reels buttons light uo for about a minute and go out, handle locks. Insert Coins light up after a moment.
Inserted several coins and nothing changed. Coin did go in the hopper and I turned the adjustment on the coin meter to lowest setting.

Opened door and pressed little white service credit button on coin meter and the blank Coins Played display changes to a 0 while the button is held down then goes back out.
Insert Coins stay lit.

Jackpot key again:
Bet one Credit and the Spin Reels light up.
Press Spin Reels button 4 time and reels spin, then stop right to left. After a moment the buttons go out.

Any Ideas? New MPU?

There are several mechanical meters inside the machine.
Did you remove these when you were cleaning up ?

If so pull them out and leave them out.

[Stayouttadabunker]

I was hoping you would gently take out the SS and SP chips, to see if a chip leg was folded underneath a chip body.
Could you try something?

Open the door.
Turn ON the power switch.
Watch the [Coins Played] window, while you press the little white Test button, about 9 times.
Stop when you see the number 4 in that window.
Tell us what you see in the [Winner Paid] and [Credits] windows?
Thank you.

There are 3 meters inside on the right. Should I remove those?

[jay]

Did you have them out previously ? and if so the answer is Yes. If you haven't touched these - leave them alone.

I did remove the chips with a proper chip puller. They were not bent or damaged in anyway.
I will do the test when I get home from work tonight. About 8 PM. Power off ,then power on and press the Test button next to the on/off switch. Am I looking for the number 4, or everything in the brackets?

[Chet]

I have never touched the counters but have no idea what has been done in the past. I'm don't think they are counting. I watched them awhile back to see if they were do anything and they weren't. I bought this not working a few weeks ago.

[Stayouttadabunker]

Yes, stop pressing the Test button when you see a number 4.
Then tell us what you see in the other windows on the display.
I want to see if the machine will tell us what chips it's "seeing".
Take a photo of the display when you get to the #4.

oh, the mechanical counters use a harness that has about 7 brown wires running down to a Black 7-pin Molex connector on the motherboard.
Just pull the black connector out of there...they're NOT very accurate( due to age) and you don't need them anyways.
Below is a drawing of the motherboard connectors.
The mechanical meters should be plugged into [J5]

No codes on any display is the short story.

I opened the front and turned on power. The reels spin after a moment and stop right to left.
On the front the denom lit up and Insert Coin displays.

1st press of Test button Insert Coin goes out. Bet One Credit lights up.

2nd press Spin Reels lights up, soleinoid for handle lock drops, Bet One Credit stays lit.

3rd press Nothing changes.

4th press Spin Reels goes out, Bet One Credit stays lit.

5th press Bet One Credit goes out, Spin Reels lights up

6th press Bet One Credit lights up, Spin Reels stays lit.

7th press Spin reels goes out, Bet One Credit stays on.

8th press Nothing changes

9th press Nothing changes.

I pressed the test button numerous times. No codes appear anywhere. I pressed the lit Spin Reels button with the front open and the reels spun and stopped the correct way. Right to left. closed door light on Spin Reels went off.  Opened the front and pressed the Service Credit button on the coin meter and the Coins Played displays 0 but only while the button is held in. I also put coins in while the Insert Coins is lit and the coin drops in the hopper but no credit is registered.

[Stayouttadabunker]

Did you pull out the brown mechanical meter harness from the motherboard or no?

Your deck button lights are working correctly....you're just not seeing numbers change on the display because you said nothing happens when you hit the Test button the 4th time....we see the 5-2 change to a 10 1 in the Winner Paid window on the display.

However, when I press the Sevice Credit button on the coin-in optics board, I get a number "1" in the [Coins Played] window, and the Coin Accepted lamp comes on.
That is what is supposed to happen when the door is open.
But...but...if the door is opened, and the optics are bypassed, the machine THINKS the door is closed.
When I push the Sevice Credit button, even holding it in, I get the briefest zero in the Coins Played window ( it goes out almost right away) but a solid number [21] error shown in the WInner Paid winow which means the Service Credit should have been able to be accessed by anyone...why? Because the machine THOUGHT the door was closed with bypassed door optics.
The question now is...did you leave the bypass wires together, then pushed the Service Credit button to see that zero come on your display?
I'm wondeing why you didn't get to see the [21] error.
I wish you had a spare display to try with your machine because for some reason or another, that display isn't working correctly.

Also, because you cannot see anything on the display, you don't know if it's registering credits when a coin goes thru and falls into the hopper.
Drop a coin in, then press the spin button....does it play?

[Chet]

I think the brown mechanical meter harness is pulled from the mother board.

I haven't done anything with the door optics. I think it is working because when I have the door open and deck lights are on then close door deck lights go out.

It does not play or show a coin registered after putting one or several coins in. I posted video on YouTube of last night. Here are the links:

[Stayouttadabunker]

Your door optics are NOT working.
That's why the machine won't accept coins, and when you turn the key, you are actually in  Accounting mode.
When you press the Bet One Credit button, that's the same thing as pressing the litte white Test button to switch between Diagnostic pages.
So when you press the Bet One Credit once, you're now in the history mode...pressing the spin button spins the reels to where they stopped on the last gamep played.
Pressing the spin button 4 times is actually giving you the history of where the reels stopped 2 games ago, and so on, and so on.
If you leave it alone for about a minute, the machine will exit itself out of the accounting pages, and reels will spin to where they were on the last game played.
I've always found that creepy! haha
Solution: You need to get a new set of door optics or bypass them.

Also,your display may be okay...check right away...>>>
Your top 6 amp fuse is blown on the main power supply underneath the cashbox.

Solution: Get a 6 amp quick-blow fuse from an auto parts store.
Make sure it has the thin wire inside the clear glass tube, not a thin flat filament.

[Chet]

The fuses are good and correct, I jumpered the door optics like the YouTube video you posted. Then did a visual inspection and tested most of the wires on the door back to the female plugs above the mother board with a ohm meter. That and finding power on several locations on the front door I think the harness is good. Since buying this machine not working a few weeks ago. I have checked the battery on the back of the board to confirm power was getting to the back, cleaned the connections with Deoxit. Put in new game and reel chips. jumpered the cashbox microswitch. The reels spin, hopper works, speaker beeps, Insert Coins is lit, the BV cycles once in a while. Good progress I think for a newbe. Not sure what to do next. a different MPU? Clear CMOS? Replace coin meter? Go Step by step with the flip cards is on todays list. Here is a link to a YouTube video That will help explain where I'm at.

[Stayouttadabunker]

Do NOT run any Clear chip...it fixes only one thing, a "61_1 Loop".
You were able to get to page 4 with the Test button and the MPU shows on the display that you have an SP731 GAME PROM and an SS6624 REEL PROM  chips...awesome! The MPU "sees" your chips....that's good.

I don't know why the display is flickering...might be camera shutter speed?
Wiggle the two black molex connectors underneath the back of the display.
Disconnect & econnect a few times.
Might be just an oxidized ground pin giving a flakey, bad contact.

Also, it looks like your door optics are okay.

You need a coin comparitor harness in order for the coin comparitor to work and accept coins...lol
Use one from another S+ machine if you have one....they're all the same.

Your "Insert Coin" lamp is lit up....that means the machine is ready to accept coins.
Drop some coins into the slot...tell us where they go....>>>into the hopper bowl, down into the drop hole, or returned down to the coin tray.

Stop pressing the Test switch...lol...you keep going into setting, options & hitting the deck buttons and changing settings...I'm sure it's ALL messed up by now...lol
Let's get your machine to accept a coin first.

[Chet]

The coin comparitor has no power to it. It goes by weight alone. No connector on the door for it. I have tried moving the harness around but haven't unplugged the connectors. I used my meter and can read cotinunity from the solder points on the board back to the female connectors above the MPU but not down to the mother board. I have tried wiping the coin meter adjustment. When I press and hold in the Service Credit button is the only time I can read the codes. Maybe it's the issue somehow or the wires from the mother board to the plugs above on the back of the case. I could build a coin comparitor harness if I new where it went.

[Stayouttadabunker]

The harness connector could be behind the coin comparitor unit.
Pull the CC off of the clips and remove the two Philips screws holding coin mech bracket, remove the bracket from the door.
You will see the white Molex on the door harness.
I'll try to find a pcture for you.

You you don't have a CC harness, then you can remove the magnetic rake behind the coin comparitor.
Once removed, the coins will fall directly into the coin-in optics board underneath the CC, and register as credits back to the MPU.
But really, you should get a CC harness.

Finally, the Service Credit button on the bottom of the coin-in optics board under the coin comparitor ONLY works when the door is in an open-state.
Open the door, press it twice (Your game is a 2 coin game), and press the spin button on the button deck without closing the door - the reels should spin to play one game.
Below is a couple of photos CC harnesses...the connector you're looking for on the door harness, would be 3-pins and white...>>>

My Service Credit button never gives me credits or credits coins. It doe not matter if the door is open or closed. I put my feeler gauge in it and did get the 21 code. I can only see the codes if I hold in the Service Credit button. I think the MPU and Motherboard needs to be checked out by a pro.
