Hey all. Can anyone assist in what error code "MET 60 MISSING" means on this Maygay Fruit Machine? I'm really loosing my patience with it, as it was perfect when I saw it in the guys house, and it was perfect when I first accquired it. Now, it doesn't come on when I switch it on, and when it does come on this message keeps coming up and it makes the most annoying alarm sound ever. It can't be surely because it's in a garage, there are no windows where dampness can get through, it has a tiled roof, and its warm inside. If anyone can assist, it will be great. I've had other machines in the garage for months, and they've all been fine like I say, I'm really loosing patience with it now :/

met60 is meter missing 

 

check the meter thats a black box normalt found on the top glass

you will probly need another meter

Yet again I've no experience of Maygay, but assuming it was working when picked up, it might be that either a meter has failed, or perhaps the wiring to the meter(s) has come loose during transit? I imagine there's going to be two mechanical meters in the bottom door (coins in / coins out and perhaps tokens in / tokens out too!), and then a refill meter visible through the top glass, normally in one of the corners.

 

Just chase the wiring from these back to the mainboard, remove and refit the plugs, and try again.

 

While you are at it, examine the condition of the battery on the board if possible. Old machines like this it is entirely possible the battery could have leaked, and it wouldn't be the first time an issue such as this was caused by battery leakage. If there's any evidence of battery leakage (normally green or white salt-like deposits), then get the board and and snip the battery off ASAP, and then I believe the general advice is to wash the affected area with undiluted vinegar, and use something like a toothbrush to agitate it a bit, then clean off with clean water and ensure it's totally dry before refitting - had to do a similar thing on my old Cluedo SWP with leakage.

 

If the meters are wired up fine, and there's no evidence of leakage (or damage to the board near the battery), then I guess the simplest solution would be to get another meter, and if you aren't sure which has gone, unplug a meter at a time from the mainboard and plug a new one in until you establish which is faulty, then bin it and fit the new one

 

I know what you mean about the alarms, I seem to recall we had a Homer's Meltdown in the arcade with a knackered battery, and after being switched off for a while and turned back on it would make this awful grating siren.

 

You can unplug the speaker if the alarm is doing your head in, then reattach it when you are sure it's sorted. There's normally two push fit 'spade' connectors on terminals on the speakers, just gently pull (and wiggle if required) until they come free, and be sure they can't short on anything, and they don't run the risk of getting caught in the door!!

bencrest why do you always say check the battery when it has nothing to do with the fault ???

 

like i said if its a front opening cabanet  check the meter (refill meter ) its normaly in the top left corner 

if you have another machine swap them over to test 

[stanmarsh14]

Already replied to this on the mecca, but suffice to say I have come across this problem before, and you would be forgiven to think that it's a meter fault.

However the devil is in the detail of the actual fault code (6.0), which is a general meter fault, and not something like 6.1 which points to one meter.

 

It's looking like it's an IC fault on the mainboard (ULN2803) which is located close to the meter plug header on the mainboard or one of the neighbouring components.

Also possible, is a track very close to the battery area that is damaged (andrew86 at the mecca who is a specialist PCB tech, well qualified to deal with faults like this), which was discovered on another members machine which I was also involved with.

The last issue it can possibaly be (Although I hope I am wrong on this one), is a power loom / PSU PCB header issue, mostly caused by excessive current return on the two ground wires (Black), thus creating a bad contact that does not work 100%.(Often see charring of these two pins at both ends of the loom, but especially so at the PSU end).

Couple of reasons :

 

1) It's an old machine, therefore there's a fair chance of a knackered battery, which if it did leak could cause a serious amount of trouble to an old machine.

 

2) As stanmarsh14 mentioned, it is possible that it's caused by damage to a track near the battery... hence why I put 'it wouldn't be the first time an issue such as this was caused by battery leakage' and

 

3) ... because I can. If you don't like it, block me or put me on ignore, I couldn't care less

As ben has said, on any old machine like this, the first concern as always is CHECK THE BATTERY, knowing what conditions some machines tend to get stored in, how long they have not been powered on, etc.

As it is on one of my FME FB based groups, dealing with a member with a zero-booting ACE machine in JPM's Impact v1 hardware..... first thing I said to him is check the condition of the battery on the processor card..... whilst the current battery fitted looks clean, there are signs of previous battery damage which also looks like it's gone for a diode or two.

This is why we say on ANY repair query, is CHECK THE BATTERY!

20 years in the amusement game and ive only ever had to change 2 batterys on an mpu and we have had machines standing in the stack for over 3 years 

 

if the battery is gone leaking or whatever  it brings up error 53 ram clear when ever you turn it on

Ok, here are some pictures I took of the mainboard (pic 1 and 3), battery (pic 4), meters (pic 5,6,7 and 8) and the lights (pic 2) that come on when the power is switched on. I took the box off, and checked all fuses and they are all fine. The message comes up saying MET 6.0 MISSING (when the machine actually does come on) but I can only count 5 meters (pic 7 and 8), so where is the 6th, and how do I disconnect the one at the top as all the cables go behind some trunking? Someone help please, as I really don't want to have to give this one away

I had a reply all written but must have forgotten to send it!

 

Anyway, errors start with a number, and that designates the type of hardware affected, any subsequent numbers help to narrow down the exact component.

 

For example, Reel errors will always start 2.x - if the error was on reel 3, you could expect to see an 2.3 REEL ERROR or similar. In your case, as stanmarsh14 pointed out above, the fact it is 6.0 means a 'general' fault.

 

It's quite hard to tell from your picture but the area surrounding the original battery location looks a little suspect, like there may be a damaged, possibly burned out resistor(?) above it. May not be causing it, but is it possible to get a better photo of that specific area? I've attached a picture showing the area I'm looking at

 

I've no idea about this particular hardware (bit before my time!) but hopefully a good photo would show up any damage there. I've no idea about that green add-on board, there may be some damage under that but I won't advise you to attempt to remove that, can't tell from here if it's soldered on or just push fit. Best wait for someone else more 'in the know' before attempting to remove it!

Yep, I am with Ben on this as the battery area looks like it's been chewed a bit, along with a possible UNL2803 etal that was pointed out earlier over at the MPU Mecca.

 

Also as you are using the old blue Ni-Cad battery (Would seriously recommend replacing this), it's possible that has partly failed and could be causing strange operating issues..... for testing / repair, you can leave this off although the machine may report a ram clear alarm which will go after a few seconds.

Also whilst running repairs, that wire which goes to the game card is for the speakers, so you may want to unhook that whilst running repairs.

This is a back door opener, with the board attached to it, and can only open the bottom door on the front, where the meters are, and coin trays. The guy has attached the battery to the top of the board and stuck it to the back of the door, and said that he had done that so that no leakage would get onto the board. Can I use one of the new green batteries that seem to be the only ones available out there today on this machine? Can I just clear one thing up, are ALL them red lights supposed to be on when you switch it on, as I saw someone else with more or less the same problem as me, and they put a video up, and all but one light was on, I've got about 3 or 4 lights out when I switch it on (see pic 2).
