Hi!

Now all of my flippers are working, thanks to robertmee and shock_me. Thanks, guys!

But now, one of my drop target is not working, which hasn't got problem before... It falls down, but not jumps up, even I cannot hear the sound of the hit.
Contacts looks good, the wires are not harm... First I thought, I damage it's cables, when I solder the top flipper (they are so close), but I cannot see nothing on it...

Hi guys.

It must be a contact problem only, I move everything, change bulbs, repair my bumpers, and now works...
The service mode not said error code, but now, everything is works...
I think, this machine stands a lot, so small errors, like this will come out slowly... Please stay tuned.
Now only one error, I've got, one lamp on the playfield. The bulb is good, if I jumpwired it's holder, then Ok... Not too important bulb, but good, if works...

Ooooo, I'm so happy.
Now I don't know, what to do with that bulb, maybe the playing will repair it...

Hm, a #555 bulb, what shows, the targets draws X's or O's...

I play 10-15 rounds with the pinball, and the top coil is smells...
I open it, touch it, and so hot, not as the bottom ones.
Can you write me exactly, how can I check it with a DMM, is it well installed, or not?

Vaaaaaaaaaa!

10points to you, guys. The EOS sticks are move a bit, so the flipper cannot split them...
But for sure I DMM it.

Needless to say, that EOS is not in factory condition... :S

Hm, now it goes from 0.04 to 0.315Ohms, when the EOS is open...

Is this can be right?

Ok, ok, now it ends almost in the end position... It opens around 1/8"

Hm, strange.

My new, top right Bally coil 0.004 to 0.315 Ohms.
My left, old, but Bally coil 0.004 to 0.300 Ohms.
But the naked, no-name bottom right coil is 0.005 to 0.016 Ohms. Is that enough...?

But, because the Ohms are changing, means the EOS ok, just the coil has got problem?
Even I don't know its values, nothing sign on it...
I think, I will change it for the new original one...
Or any else can cause this?

So what do you think?
Will the problems solved, when I install the original coil?

My only question, what do you think, these wrong values from the coil means, that coil is wrong? Because if yes, then in the morning i will change it immediately...

Sure, but I don't know, Ohms are wrong because of this.
Then, in the morning I change.
A solder everything to the original place. Means, I follow the thin and thick wires of the coil.

Hello!

I change the coil to the new one, and wonder, the buzz from the relay is gone.
But I still count low Ohms, when the EOS is on... From 0.004 to 0.020 . But both 3 coils stays cold, when I play, and odorless...
I got a few contact problems, at the connectors... Especially the feature board's (needs to move a bit, when 1-2 lamps not lighting), and one on the lamp panel (then few playfield lamp go dimmed).
But else, looks perfect, except that one playfield lamp...

I'm sooooooooooo happy.

So, robertmee, and shock_me...

THANKS!

Today the whole family (5,15, and adults) was here, we plays 4 hours on the pinball, without any malfunction...
Will we needs any test?

You should get a statue, I say...

Thanks a lot.

Here, in Hungary, only one X's & O's flipper here, as I know, and even the world there are not too much...
I try to save it. Tomorrow I make a few pictures from it, you should know, you help on what...
Now, only that one lamp is on the way to be perfect, I hope, in this forum we solve this problem...
The real satisfaction: the family feeeeeels so good.

Hm, guys, when did you plan to go to Europe?

Hi!

I upload a few pictures to my other thread, from the present condition...

Hi!

I've got a question again.
I play with the pinball, everything works. Just 3 ball-trough switches sometimes forget to work, but I think, they just need to be adjust.

But, if I play, the bulbs dims a bit, if too much lit. This happens too, when I use flippert. Not too disturbing, but I want to fix it, if possible. Is there some electical part, what can be wear out? Now, as I see, everything is original on the pinball, just I change a few parts...

Thanks!

Now I test it, all bulbs dims. GI, inserts, even the backbox, too.

I mean a few play,under "test".
All bulbs are OK, just it seems like,if too much things working in same time, the voltage drops a bit...
Should I check the main capacitator somehow?

So, anybody any idea, what to check, what to change?

Hm,ok, can I check it somehow? As i see with DMM, while I play, the voltage is changing +-0.5 volts. Or that is normal...?

Hm, before I order a new capacitator, how can I test it? What is the value, what I should see, when I play?

Thanks,then ok, i change it, if this can cause the dimming... Tomorrow i upload a video,and then you can see, that is normal habit,or not...

So, here it is, not too good video, but I hope, the dimming is visible...

Then OK, and sorry about the vid quality... Motorola can do this. But must use Motorola, because the upside down Williams logo...

So, thanks for the help, if nothing to worry, than I let it. Just I try to prevent further problems...

Hi!

My pin was perfect, until today.
While I play, the F1 fuse (20A) on the rectifier board is blown away. I replace it, but that is immediately does the same. I think, it must be a short circuit, or something there. Everything is working, except the playfield's lamps. The GUI and PF too, including the feature board. The bacbox is OK, so as the displays, flippers, solenoids, scoring, sounds... So, just the lamps are wrong... Any idea, how can I find the problem, and how?
Thanks

Mal

Can I check it, or test it somehow?

Hi!

My past post was wrong, the GI laps are working, just the playfield lamps, and the feature lamps are wrong...
How can I check the rectifiers? And which can be the wrong? A read the pinwiki, but not not clear, how to test it...
Thanks!

Sure I plan to repair it, I does all the repairs on the pin before... Just that is not clear, how to test them... On the pinwiki there is a correct writing, but not matches with the pictures, next to the text... I should follow the text, or the pictures...? That is not correct for me...

Hm, i try to test both of them. The 4 poles are " + ", "AC", "AC", and the fourth one must be the " -" . I follow the video, but the values are totally different, then here. For example, the values between ac and + are the same, both ways. Or one way 0.6something, reverse 1.something...
Is that possible, the 2 rectifiers goes wrong at the same time...?

Means, I should replace the fuse, and unplug all connectors(2 backbox, cabinet and playfield) from the rectifier board, except the two transformer input connectors, and then turn on the machine?

Now, I connect only the transformer input, the fuse blown immediately after power on...

Both of them?

Oh, thanks, I see, I can follow on the panel's back.
What do you think, if I change one, should I replace the other one, too? Or these parts not wear away at roughly the same lifetime? Because it's cheap, maybe worth to change both.

Ok, thanks a lot! I will buy 2 piece...

I de-solder it, and now I found the error with the DMM.
Between the "-" and one "AC" both ways nothing happens.

Thanks, I change it soon!

Until I will buy the bridge rectifier (tomorrow), I start to repair the shooter rod. The spring was broken, the rubber was old, the rod was deformed... I will buy the parts tomorrow, and fix it.

More pictures tomorrow, after repair...

Kbpc35-02 was the old one, Gbpc3510 is the new... What do you think,it will be good? The shop said,they are the same...

Thanks!
Wire leads? Means,i can solder it?

Thanks,I bring the old one to the shop.
I solder it to the board,and works perfect!
Is that possible,now my lamps are brighter? Or maybe that is just an illusion...
Thanks for the help,guys!

Thanks for the detailed answer!
Looks like, I need to rebuild that panel soon...
The black thing on the fuse holder is something paint,or beer... Before I clean the board,the whole panel is covered with it. I will clean it properly soon. Can I use the pinball,before I change the other rectifier?

Hi!

Looks like the pin is ok, I play 1hour today without any problem...
But I found a strange thing... If I push the start button any time,during play,the game restart imediately...
What can be the problem?

Ah,thanks,i tought that is a malfunction...
Then i just need to adjust the button a bit,now too loosy...

Today I does the last two cleaning on the machine... The kick-out hole, and the targets.
I forgot to make photos from the first one, but here are the pictures from the targets... And I made good hi-res photos from the horse shoe, if anybody needs repros...
