Hi
I have had a fair few pinballs over the years but sold them 15 odd years ago to finance building works
I had that itch again and have just picked up a bally xenon in pretty good shape but has sat in bits for near 10 years
And im realising im abit rusty on these early ss games

1st question one of many

Mpu plug j2 the top wire the yellow with red trace ....it was floating about I think im right it goes onto pin 1 can some kind person confirm this fpr me

Also in switch test mode it sits in sw 1 end of tube..but occasionally pops up to sw7 sw8 and jumps around abit....is this somthing thats vommon and hopefully straight forward

Thanks in advance j

Well thanks for that
That answers my question in a round about sort of way...
I thought I cant be that far out! when I just went back to check its actually the white with red trace that was rougue
Which does indeed go into no 1

Thanks for the quick reply

Nope.
It still sits on switch 1
End of tube switch when in switch test mode
And like I say occasionally jumps up to 7 and 8

It has a few more gremlins as it also can jump straight to tilt.

Also credits jump up in massive leaps
But it ignores start button
Like I say its been sat in pieces in a garage for a fair few years

I didnt expect it to work from the off
90%of lamps work
Displays are nice and bright and steady
All solenoids fire strong so I'm hoping when I get these little faults it should be great

Like I say I haven't had a ss for over 15 years .... so I know I need to get up to speed

Any pointers would be real helpful

I'll work through it one fault at a time
J

It actually has an older altek mpu fitted the earlier one with the remote battery pack.
This game looks to have been shopped about 15-20 years ago and hasn't been used much since
Or messed about with

Tomorrow evening ill factory reset the mpu and see if it settles any more
And pop some new batteries in just to male sure everything is happy

Please excuse typos I'm using my phone for the time being

Good morning..
Well it is here
May I ask if the fist mpu diagram was a generic bally diagram or was it xenon specific

I have in pin

1 White Red trace
2 nu
3 grey white trace
4 white with yellow trace....very faded so could be wrong
5yellow red (or brown ) trace

Thats j2 on mpu counting down from top marked 1
Down to keyway

Hi just got home and started again for a few hours
It settled down possibly being in a nice warm house either than a cold garage
More life and bow im on switch 27 tube switch
Switch is working and when I activate the switch 27 the next switch with an issue is 25 shooter lane

I have the manual here but not the wiring diagrams and at the moment I only have a phone to view them and its awkward to say the least

OK cleared all switches
And its now seeing start button
Now pops straight into tilt when pressed

Moving on slowly

I'll have a look
If I activate tilt switches manually in switch test it shows sw 6 ...credit button
So somewhere it must be linked

Answer to removing bottom orange from plug..
It goes straight to tilt on startup

No sits happy

Even tilts on the start switch with no credits
Back to a few posts ago
Looks like someone has already snipped the capacitors off...
The only ones I can see are on the flipper buttons and plumb bob tilt...and I have just removed that one too

It plays up with j3 plugged in
I'm wondering if its in the door

I've unplugged that obviously cannot press start button to tilt it...

But here is what I think is wrong
But I jave no idea why just yet

In switch test all switches seem to be working
But if I short the ball roll tilt with the ball it flashes 07-07-07-06-06-07-06-06-0-6-07-06-06 etc
It seems to be a conflict somewhere and it is triggering both 6 and 7 switch in switch matrix
Obviously why start button is tilting it

It flashes 06 probably 3-1 times

Still i do feel like I'm getting somewhere now

With thanks to yourself

And just noticed if I am touching the ball on the tilt mech
When I earth the door with my hand ....the top right pop bumper pops ???

At this point I will add I am an electrician by trade 30 years ....... didn't known could do that though

Back too it
Just had a game .I think the
Fault was down to the final ball out switch 02.

It was just about on its adjustment I guess a ball has been sitting on it for many years so was on a fag papers adjustment
Just re adjusted and all works really well
Obviously it won't be the end of my problems but its good to see a game unfold .....
And the speech works which is a real bonus

I'm gonna put a few games through it to see whats misbehaving already one roll over button up top is sticky

I'm not 100% its the route cause but I will keep going

I promised the kids it would be done fpr Christmas

Before I hit the sack.
One thing that is bothering me

The centre pop bumper doesn't work but when the skirt switch is activated the top rhs bumper triggers

Is this a common thing
And any suggestions before I go mad again

Back again.

Games playing well...especially considering its been stood for so long
It goes into tilt on first ball of player one if playing multi player ....
Definitely somthing to do with ball release switches as it then goes round all 4 players and balls perfectly.
I think it may be a tad out of sink..

The middle pop bumper fires on the solenoid test
And it sees the switch in switch test....
So why wouldn't it fire in a game mode

Any suggestions

OK very lazy question now.
What diodes shall I order

Much appreciated again
At least my lad can now have a game on it

I'll order some.
Although its just started to work...but obviously and issue somewhere

So as it stands the game is now playing well and all functions are working.
Fingers crossed but im sure somthing else is gonna bite me

The last switch on the ball release seems to affect the game massively

OK all caps and diodes ordered and im on it.
Although the lower ball chute issue seems more like a set up issue

You can play with the skirt off and you can see the 2nd ball bounce back and fowl sw 28 which puts the whole game out of cinc as no ball is showing on sw 2
Not very often but enough to be a pain

Cap fitted diode changed
Minor service and pop bumper is very responsive sharp and strong.

Ball Shute is now working well to date
The ball seemed to bounce back and foul the micro sw in trough ...(think 28 from memory)
So I reformed the wire form a little and snipped about 2-3 mm from end so it was sitting just under half the ball so now when it gets so far it let's the ball free sooner..
To date its been perfect as has the whole game...

Now onto getting all lamps working

Thanks again guys

I'm back...
All has been very well.
This game has been pretty faultless ....Still is..

It must have had 200 games through it this week

The kids were playing all was good.
They stopped and left it switched on in attract mode or the middle of a game for half hour whilst having dinner.

When they went back the sounds gone
You get the small point score beep but no speech or background.

The speech boards work when test button is pressed and go through all phrases
I've reset the altek .
And tried all the sound modes in test 18...

And nothings changed.

Obviously I'm glad the speech is OK but why would the speech and bonus mota release etc just disappear

Any ideas

Thanks again in advance

I'll check but its been fine for weeks
Just shut off when left idle for half hour
No dip switches were touched

I'll have a read of all that later.
Apparently the sound came back for a bit earlier today ..then went out again.

I went to turn the pots..the top one has been replaced already...when I opened the back box whilst it was in play it briefly woke up??

Them went off again straight away.

I would assume the pots are fine as when you press the test button it goes through its whole vocal repertoire

It just won't say a word in the game

And also on a foot note all sounds have disappeared now
So its abit like playing an EM game at the moment
Really frustrating as the game is otherwise playing and behaving really well

It can't be much as the start sound is there
And the speech works on the test button

No scoring at all or anything in play

OK I'm with you on re pinning.
But as I don't have any here I'm still trying to suss out the route of my troubles

Now I'm pretty sure if it was a dry joint...(I have re flowed the header pins )
As When in a game and I went around wiggling poking and generally disturbing everything at some point i would get a bleep on boooohh.....nowt

I have just taken the vocalizer board out and seen this nasty repair .....
But like I say the speech works fine on the test button...

Now my thought process is taking me to the vintage alltek board as the trouble as I am not getting a start up noise on the test button.

And its not getting any sound in the game
I'm obviously getting power in and out of sound/vocalizer as the rest button on the board is working

Its just not getting a signal when scores are hit
Although the scores are all working fine
