[Restoration] Gauntlet - warrior needs food ...

[Superully]

today i checked the voltages on the pcb, was a little bit low at 4.99 volts. turned that up a little bit, but the graphic issue on the title screen still remains. however, as i've said before, no graphic error at all appears on the other attract mode screens or during gameplay, it really is only the title screen. any ideas?

one more thing came up: i also found a coin counter, which was missing on my gauntlet. quickly installed it and gave it a test: you can hear the clicking sounds of the meter, but the display doesn't increment a bit, it stays steady at 35400. you can also see that the counter is trying to move one number up, but somehow it fails to do so. could this be a mailfunction of the meter itself or isn't it getting enough power?

Did you connect it to +12V?

well, here's a photo of how it was connected on the machine where the coin counter was pulled from: the right two pins of those four pins on the sound board



don't know if that's +12V or not (my schemativ reading skills are still limited)! as i've said: the clicking sound and the movement is there, the numbers just don't "flick" over, as if they aren't being pushed enough ...

could be that its stuck, i dont know your mechanical skills, but i managed to "reset" once a simular counter in a copymachine (which i did for a living for some years)
so if you dont feel like you are losing something if you destroy it , open it up !

that's the problem: i don't know how! this looks as if it came in one piece from the start (which of course it didn't, but i can't seem to find a crack to open it up)!

as far as i remember it can open like a cover so maybe there is some line in the bottom ? (wireside)
can you make a pic from the bottom ?

or if youre very carefull you can maybe saw it open with an ironsaw:

Measure the voltages at the connector. And maybe you can test it at the other two connectors (for the second coin counter)?

I might have a spare counter...

first of all: i don't think there was a second coin counter, because no matter which of the four coin inserts i use, the coin counter clicks - i guess this means that one counter measures all four slots. have you been able to judge from the schematics why there are four pins?

I might have a spare counter... 

for the same voltages?

Because the wiring diagram shows a second counter connected there

AFAIK they pretty much all run on 12V.

can you post a picture of that and explain it to me?

the ones i have in my "collection of spare parts" all run on 10 volts!

btw, how do i measure the voltages on those pins? one lead of the multimeter on the left pin and one lead on the right pin? if that's the case, the meter measures 3.72 volts!

Check the game wiring diagram, sheet 21 in the schematics pack. Lower left corner.
According to this it's AC not DC, try that.

thx, found it! where can you see that it's AC instead of DC?

and if i measure it with the multimeter set to AC, one lead on pin 3 and the other on pin 4 i get the following results: 0.0027 volts

[Laschek]

It says 12VAC at the input connector.

[Superully]

and what about those measures i took? do they make any sense at all?

Obviously not 
Surely the voltage is too low, for whatever reason 

Why need a coin counter anyway? I mean, it's just a friggin coin counter??
