Title: Paging Jim from Ohio - Mustang 62 error code Post by: sbmania on April 27, 2013, 01:25:29 AM I understand you are the NLG expert on Universal slots. I just got in a Mustang which I am having trouble fixing.
When you first turn it on, it comes up and says Inset Coin, although the upper LED display does not appear to be lit. After about 5 or 6 seconds, it shows Tilt and error code 62. I can not find a reference as to what this means and don't know where to start with fixing it. Can you provide any insights as to what is wrong and what components might need to be replaced? Also, I tried the reset procedure mentioned in a previous NLG post but am having problems. I can't find the upper unit reset buttons. There are two units up top - one mounted in the center of the head and one mounted to the left wall of the head. Which one should I be looking at? Where are the buttons? Also, both units are covered with a gray sheet metal housing. Does this need to be removed? The upper display sort of displays an occasional faint line at the bottom of the display but that's it. It never really lights up. Any help GREATLY appreciated! Title: Re: Paging Jim from Ohio - Mustang 62 error code Post by: uniman on April 27, 2013, 01:41:14 PM Welcome to NLG. I found a couple of old threads on the Mustang, they may help;

reset the bottom unit using the method described, then reset the top unit .Turn power off, hold both buttons down, turn power on hold for a few seconds, you will see a red led start to flicker and the three colors should show up on the top display in a test pattern. close the door and lock, machine should ready to play. http://newlifegames.net/nlg/index.php?topic=17312.0 see picture in this thread. P.S. this machine is for sale Title: Re: Paging Jim from Ohio - Mustang 62 error code Post by: sbmania on April 30, 2013, 10:20:35 PM Here's a follow up - still need help. I got a second working Mustang and found the problem is isolated to the top Bonus unit. On the broken Mustang, the LED does not light inside the Bonus unit like it does with the good unit. None of the reset procedures worked - the LED in the Bonus unit still will not light.
Anyone know how to troubleshoot the Bonus unit itself? I switched the bad Bonus unit to the good mustang and the game would not come up. I put the good Bonus unit in the bad Mustang, and it came up after following the reset procedure, so I am sure the Bonus unit is actually bad. What does the lit LED signify? Thanks! Title: Re: Paging Jim from Ohio - Mustang 62 error code Post by: sbmania on April 30, 2013, 10:24:23 PM Just to clarify, of the two LEDs that can be seen in the front left corner of the bonus unit, LED 4 is flashing onthe good unit, but not lit at all on the bad unit. The LED next to LED 4 does not light on either unit.
Title: Re: Paging Jim from Ohio - Mustang 62 error code Post by: Jim on May 01, 2013, 01:30:53 PM like I stated in my reply, there are two units that work the top bonus. the first unit is a power supply, it provides +5vdc to run the bonus unit. I believe the red led indicates that the +5vdc is good,
the second unit runs the top box display and communicates with the lower cpu. when this unit is up and on line the second red led flashes, indicating that it is communicating with the lower cpu. I would start with the power supply, if its bad nothing is going to work. in the Mustang that I have these are two separate units, the power supply is attached to the bonus unit . the power supply is the unit on top. Hope this helps Jim Title: Re: Paging Jim from Ohio - Mustang 62 error code Post by: sbmania on May 01, 2013, 04:50:24 PM I'm not sure I'm understanding you correctly. Let me explain. In my Mustang, there are two gray metal boxes in the very top section of the slot (behind the upper glass). One is screwed to the left wall of the top section and the other is screwed to the base of the top section. The problem is definitely related to the unit which is mounted to the base of the top section, as I replaced this unit with another identical one from a working Mustang and the problem was fixed. The unit screwed to the left wall of the top section is not the cause of the problem. (By the way, this unit appears to generate 24vdc. I don't know what else it does if anything.)
Inside the broken unit, there are two boards - a smaller board on top and a larger circuit board on bottom. On the bottom board, there are two LEDs - in the working unit, one of these LEds flashes continuously. In the broken unit, this LED never lights at all. Can you tell if the problem is related to the top circuit board or the bottom board? Any idea what could be wrong, or what test points I could check? Does the little top circuit board supply power to the larger bottom board? If so, what voltages? Also, the fuse is good. Hope this clarifies my situation. Title: Re: Paging Jim from Ohio - Mustang 62 error code Post by: Jim on May 01, 2013, 08:07:54 PM I doubt they made two different type of Mustang machines. I'll take a picture of the unit.
I have the larger circuit board that has the LED's and the reset switches on the bottom, and attached to that circuit board above it is the power supply. the power supply only provides power to that board and it only provides one voltage and that one voltage is +5vdc. I will dig out my schematics and wiring diagrams for this machine, I am doing this from memory, but I think I am right. Jim Title: Re: Paging Jim from Ohio - Mustang 62 error code Post by: uniman on May 01, 2013, 08:34:14 PM Could it be possible that the unit mounted to the left side wall is a casino communication board and not related to the bonus meter?
You should post pics of all boards in your top box. Title: Re: Paging Jim from Ohio - Mustang 62 error code Post by: Jim on May 02, 2013, 11:31:48 AM I looked at my machine last night, there are two metal covered boxes in the top box. the one mounted on the top left hand side is the logic board and power supply(+24vdc) that run the red LED bar on the top of the machine.
the other metal box on the bottom left hand side contains the logic board and power supply that run the front led display, (display's the numbers) inside this metal box are two circuit boards, the bottom one has an interface cable that goes to the front display (similar to a DB-9) it also has four red LEDS on it . the one in the back left indicates the power supply is good. the top circuit board is the power supply(+5vdc). This power supply also provides +5vdc to the front display(connector on right hand side-pink wires) as well as the operating voltage for the bottom circuit board. my guess (I have seen this many times) the power supply is BAD. Hope this helps Jim Title: Re: Paging Jim from Ohio - Mustang 62 error code Post by: sbmania on May 02, 2013, 11:47:37 AM That makes sense since the LED is not flashing on the bad unit, which it does with the good unit. Do you have a schematic of the power board or any idea which component usually goes bad on the top board? Many thanks!
Title: Re: Paging Jim from Ohio - Mustang 62 error code Post by: Jim on May 02, 2013, 12:14:03 PM not really, for the time involved trying to troubleshoot a switching power supply , for me its cheaper and faster to replace it. find a switching power supply that meets the specs. and replace it. shouldn't cost more than 50.00. I believe its +5vdc @ 6amp according to the drawing.
Check with mouser electronics or MPJA in Florida, they have a line of reasonable priced switchers. you'll just have to incorporate it into the wiring harness, there again not very difficult. Hope this helps Jim Title: Re: Paging Jim from Ohio - Mustang 62 error code Post by: sbmania on May 24, 2013, 03:59:17 PM As an update to the Mustang error code problem, I was able to install a switching power supply into the upper unit and the LEDs on the logic (lower) board now light, showing power is good. However, the upper display still will not light and the game still has a 62 error code. I have made several attempts to clear the error with no luck. I am assuming the upper logic board which drives the upper display is also bad. Any ideas on what could be wrong with that board, or if a replacement is available? I came across a second Mustang slot which also apparently has a bad upper logic board since the 5v is good but the upper display also does not light on that slot either.
Title: Re: Paging Jim from Ohio - Mustang 62 error code Post by: Jim on May 24, 2013, 04:49:46 PM you have to clear the machine in the proper order.
first the lower clear, involves pushing and holding the button while you power up. second, clear the top box unit, involves holding the two buttons down while you power up. there is also a battery on that board,(top box unit) but when it is bad it usually will allow a clear, if you turn the machine off for a few days it will require another clear. Jim Title: Re: Paging Jim from Ohio - Mustang 62 error code Post by: sbmania on May 25, 2013, 07:47:15 PM I did do the clear in the proper order but still nothing in the display and a 62 error remains. Is it likely the logic board which drives the upper unit is bad? I can't find a schematic and would have no idea what to look for.
