Talon claw machine keeps resetting

Not sure how I missed all these updates. Nice to see there is someone that can maybe fix the issue. I got conflicting information from someone that sells an upgraded motherboard but is no longer in business mentioning the problem is a transient power issue by the original motherboard design. I will reach out to the person mentioned for sure to see if I can buy the parts for the repair. I hope to post an update soon. Thanks.
 
ive had this issue on many talon and treasure chest cranes. Its never the board as in an issue with a bad part, its a bad design. ive swapped power supplies and connectors over and over and tried multiple working boards and the same stuff happens a few weeks later.
the board resets due to its programming. it looks for a volatge drop and resets.
What we need to do is figure out how to put an update on the board or something to make it not care so much about the +5 being perfect voltage to reset the game.

Interesting thought I will run it by my step dad. He has a chip programmer and has hacked some code before on different projects to do what he wants. He is pretty busy though so not sure how much of an interest he will have but it is worth an ask. On another note as a last resort I want to basically make a conversion kit for this to use an Arduino board. So basically you buy all the components and drop it in place. Any schematic or wiring information would be very helpful in making that project come to life if anyone has something please share. This claw has been sitting around my house for 2 years and I am willing and ready to make something work for it to get it out of the house. lol
 
I just picked one up He told me it was doing the reseting thing and took it apart. I put it back together now when plugged in the only thing that powers on is the bill acceptor. Any thoughts.
 
That does seem odd. Verify your connections. Did you remove the control panel from the machine? 110 connects in the back. Also plugs from the machine plug into the outlets in the control panel. I will wire mine back together soon so I can try some suggestions for the reboot issue.
 
Here is what the back looks like. I bypassed the switch at the bottom since I always want it on. Hope it helps some.

Thought I would give an update. I have run into a bit of a catch22. I have a running repair history on this machine at the below link (I will be using references from there):
https://www.fabozzi.net/talon-claw-machine/ (click the troubleshooting tab after scrolling down for test points)

Video Please Help Me Scott Explained:
  • Test Point 1 is around 5.25v
  • Test Point 2 is around 5v
  • Unplug machine and plug in it boots properly
  • Randomly reboots
  • While machine is still on crank up voltage
  • Machine is stable no reboots
  • Test Point 2 is around 5.4v
  • Unplug machine and plug in it does not boot up at all
    • No claw movement, no coin lights, bill reader has red light
  • While still on turn voltage all the way down and slowly turn up
  • The game boots up properly but will randomly reboot
  • Catch22
I have emailed Scott to see his recommendation.
 
FINALLY!!! This appears to be fixed!! I have said it before and it wasn't but this time it is looking very promising. Machine has been on for 24 hours with no reboots as far as I know (I need to review some overnight video footage). In the past if I left it on "reliably" after about 4-5 hours it would start rebooting continually until I unplugged it. This time like I said it has been on for 24 hours and is still acting normal. I will be doing a full write up on my website but for this forum here are the highview steps I took:

  • 12v pin on jamma connector at very bottom of board can get burnt (I fixed it by globbing solder to extend the pin to allow connection on the connector)
  • At J1 solder the last two ground pins together for better ground (I soldered a thicker cable here going to the ground of the power supply as well)
  • Check your 5v cable going to the power supply (this was the reason for my voltage drop and the final fix for mine, connector was black)
  • Check the connector at J1 (I bypassed it for the 12v, 5v, and ground by soldering a wire straight to the pins on the board)
  • Zip tie the lockout coils (mine was already that way)
  • Once all that is done I dialed in on the voltages at U9 like so:
    • Turn machine on and at pin 10 and 20 at location U9 it should read between 5.3v and 5.4v (turn the knob up on your power supply till in range)
    • Unplug the machine and plug back in and it would not boot (Voltage at U9 randomly changed which is odd. Dial it back down between 5.3v and 5.4v)
    • Unplug the machine and plug back in and for me so far it is good to go.
Huge thanks to Scott (http://www.aslex.net/) and people guiding me on this 2 year fix

Hope this helps someone and let me know if you have any questions.

Okay so I went back and everything is hooked up like it could be. I'm only getting power to the bill receiver. It's getting random voltage at U9 when the power is turned down until the reading is steady the highest voltage is 1.4. I did like what you did in the video with the power supply but the power never cut on like it did for you. I also reached out to Scott but never got a reply
 
That is way too much of a drop. I hardly have any voltage loss from the power supply to the first test point. Check the J1 connector (first pic) and check the Yellow wire. Unscrew it from the power supply and examine the end.

In the second picture I soldered the cables to J1 to create a reliable connection because I wanted to bypass the connector to see if it was the issue and for me it made a big difference

You still need the connector plugged in though for 110 (black and white cables next to each other) but you don't need to connect the yellow and orange wire if you solder them to the board

The black cable soldered in my pic is the extra ground cable going to the power supply. Those two pins are recommended to be soldered together for better ground but I made a cable coming off as well going to the power supply to be sure of a good ground (probably over kill)

This machine is extremely picky about the voltages. If they are out of range the machine will not turn on properly or it will randomly reboot.

Let me know what you find out.

So I must not have used a good enough enough groud the first time I checked. the test point I got it in range power supply is 5.38 and test point 5.31 this time.
 
7959.jpegis this where I'm supposed to test from or does it matter what terminal? Also just went back and tested the power supply is 5.60 and test point is 5.53 now
