Daido Top Gun

[jparis]

Hello!


I’m new to the site and fairly familiar with the machines (Frozen nights, Zak Zak, Aztec, HoundDog and now a Daido Top Gun). I just picked up the Top Gun knowing it has the error.


The previous owner said it worked for a while with quarters. He came back later and turned it on to find the error. He attempted a reset based on what he knew. No luck. So I bought it from him.


All five of my machines are all different with coin mechanisms or hoppers or practically everything. So there went my idea to swap out parts and troubleshoot.


The machine is extremely clean and no evidence of burned wires or electrical parts. No electrical smell.


I took apart the coin mechanism. A piece of credit card was added as a shim I’m guessing for coin usage conversion.


The hopper was taken out and run on a power supply. It rotates and spits out tokens just fine.


The power supply is clean. No evidence of burn damage or shorts. The fuse was good. Someone mod’d the reset key with a rocker switch. I’m not sure if the reset procedure with the push button switches is working. They don’t appear to change anything.


I’m thinking it’s a sensor on the coin mechanism. Does anyone have recommendations on how to test it?


Pics are provided to show the error message. The coin mechanism, power supply and the main board with LED lights.


All LED lights function properly except the one labeled LD5. It doesn’t seem to respond to any button or switch. Could this be correlated to the coin mechanism somehow?


THANKS. Any information is appreciated.

Welcome to the forums !

Where's the picture of the coin mech ?

You can see the piece of credit card wedged in there. I’m assuming that’s for coin usage? No visible damage other than the roughed up screw. Do you know how to test the sensors?

[jparis]

Not sure what happened there. You can see in the above pic the piece of credit card wedged in there. Assuming that’s was a mod for coins. I don’t know. Is there any way to test the sensors on the count mechanism?

[bjab]

Have you resolved you issue ?

[bjab]

Are you getting an error code such as E2 or are you just seeing ERROR on the scrreen ?
Have you tried removing the credit card shim and tried the machine with tokens ?
Are you doing a full reset with the proper procedure ?
You mentioned you think someone replaced the reset key with a rocker switch ? Could it be possible that the OFF and ON switch position is backwards ?
Can you post a couple pictures of the sensor board and also the sensors ?
I believe i have replaced those exact sensors on one of my machines but I can't be sure until I see pictures. I believe it might be the same coin mech though.
Is there another wire harness that goes on the sensor board that has yellow wires that you dont show in your picture?

Thanks for the reply.

No error code as typically found in the payout or win screen. (eg., CJ, HE, etc). Just the error in the video screen with the sound system blasting the “baaaahh. baaaaah”.

I haven’t removed the plastic strip and tried it only because the previous owner said it worked as is and provided video. I have a replacement arriving today that’s untouched and has good sensors.

I’m a token guy. He was not. He said it worked under quarters but then it went into error.

I’ve done the full reset procedure as I do with my other machines. This doesn’t respond to it.

Someone used a cheap rocker. I replacement it with a SPST toggle. I’ve tried, switched wires and tried again. It doesn’t respond to the wire swap.

Pictures to follow.

I’ll double check the harnesses. I do not believe there are any plugs that are not plugged. There are no harnesses or plugs just hanging there not plugged in.

I’ve removed the coin mech. I’ve removed the overhead video screen panel. The main panel behind the reels has been removed and inspected. Nothing shows any signs of overheating. Blistered or popped electronics, etc. There is the one LED on the main panel that will not illuminate. The pic above has the purple arrow pointing to it. It doesn’t respond to any button, switch or lever. All the other LEDs illuminate and respond to some action.

The two fuses I’ve found are good. I replaced them anyway. The hopper was tested on a DC supply and it shoots out tokens like a weapon.

I’m at a loss.

Could it be an issue with the reels? Would they need synced? I’ve never had this problem with any of my machines.


thanks again!!

Here is a close up of the coin mechanism sensors. I removed the card shim (no change).

Here’s also a pic of the mech installed. No unplugged harnesses. No yellow wires visible.

and a video of the main board with all working LEDs but the one.

Looking back at your picture of the power supply I notice the top switch is pushed in the ON position, It should be in the OFF position for Play mode .... but maybe you just took the picture
when you were in the middle of a reset.

Also in the same photo, the red wire next to the word "setting" , looks in ditress at a sharp 90 degree to the black thing. Is the red wire attached to that and if so, is it OK ? Where does that go exactly ?
Just looks funny to me.

Yeah your coin mech looks like the same one I put new sensors on. What is the numer on the sensors ? When I changed those on mine, it was very challenging to do so. Took me a long time
but it did fix my problem of not recognizing the tokens.

Will yours even accecpt tokens and if so does that non lit LED flash each time you drop a token in ?

I'm just trying to help.

Thanks for the reply and good comments.

The rocker switch was just in that position during the photo. I’ve replaced it since then with a SPST toggle.

The red wire next to the power supply is going to the hopper. There is a wire bundle with plug to the hopper. This just happens to be separated from that bundle but it actually goes to a sensor or something. It looks manufactured there. I’ll verify it though. ����

I read on different posts about a super capacitor holding a charge and keeping the machine stuck in Error. It is the small SC on the door behind the video screen. I tested the charge with an LED and then shorted the capacitor to hopefully “release” the error. It worked and the screen no longer displays “ERROR” and the sound effect has stopped too. However it still won’t allow a proper reset with the power supply.

The new condition is it has flashed the “C” on the credit window. So coin mechanism or the sensors.

It suddenly flashes “8” on the payout window and then the hopper ejects eight tokens.

You can hear the coin mechanism relay clicking randomly.

I saw and felt it move and saw it attempt to “sync (?)” the far right reel.

The stop button back plate will randomly illuminate. The buttons too.

It seems like it’s trying to wake up and work. I have a replacement coin mechanism coming in the mail. Hopefully the sensor situation gets fixed.

[jparis]

Oh yes, and the LED LD5 is fully functioning. I found a label inside that addresses it LED. LD5 is for the overflow hopper when it’s full. I shorted the sensors for the overflow hopper and the LED illuminates.

so all LEDs on that board illuminate or turn off with action from a button or switch (or hopper overflow). IMG_9793.jpg

It's hard to tell in your power supply picture , but are the reset and settings buttons near the bottom, ok ? One or both aren't kind of stuck, are they ? The buttons themselves look deforemed a bit.
For example and have you ever had this happen...Like on a new, now a day LED flashlight, the on and off rubber push button is usually on the top end and I've had it happen that the rubber button gets stuck on, under the casing or enclosure.
I had to wiggle it a bit to free it loose to let the actual switch button underneath the rubber, release it's self. . I don't know if you know what I mean though. Are those reset and settings buttons soft like rubber, or are they hard plastic. Your's look melted or something, but maybe it's just a bad picture.
Man.... I'm "fishing" here for you ! hahaha Seems like you resolve an issue and then something else pops up !
