Put games on the Bingo counter and see if it will play. Maybe the coin switch is messed up.
If it powers up............. use this link to help you T/S the bingo.
Go to 'how things work" to explain how the Bingo works.
Then others should be able to help you.

Manually add games to the Credit counter.

Manually actuate the plunger to step it up to put credits on the counter.
I never use the coin slot to play games, but that's just me.
See photo...... @ Red arrow.

I would guess possibly the credit counter (step-up step down stepper) is at maximum & there is a decrement plunger you can operate
..........................................
The picture in post #15 shows the Counter at 0000.
You can move the counter both Up and Down. Maybe you are moving it in the wrong direction!
Just a thought.

WoW......... lots of 'Negative comments" .

There is a lot to learn with these Bingos. Take your time; after you fix one, you will be looking for another one
or two. I know........I have 12 of them!
Enjoy the 'learning process".

Mark,
If you look at the schematic and manual, you will see that the Red/green wire is labeled #14.
You need to know the wire # when you are trying to trace wires.
See attached Pics. You need to have a copy of the Schematic and manual to T/S your Bingo.

You can see info on your 'Miss universe" at this website.
Just click on the game functions. They explain what each function does.

Mark,
Jeff Lawton ( Mr. Bingo) did a video on "Miss Universe" at the York, Pa. show a few years back.
The audio is not very good, but maybe you can learn something from it.

Do you have Credits on the Counter ?
I'm not familiar with this bingo, but if you power the Bingo "Off' and then power it 'ON', the Credit counter
will reset to 0000.
That is why I put a lot on Credits on the Bingo when T/S.

Where can you buy these and how hard are they to replace? This thing is becoming a real piece of work.
Thanks again,
Mark
............................................
Actually your Bingo looks very clean. Don't get discouraged, you won't learn everything in a week
or 5yrs.
Nick mentioned a Jim Holder who brought a Miss Universe to the York show a few years back.
Maybe he can help you with the 'game play' of this Bingo, if he still owns it.
I don't know his "handle" here, so I can't contact him. Maybe Nick knows how to contact him.

Keith made a Nice short video on cleaning stepper units.
Maybe it will help you or others. I always clean all my stepper units before I even power on a Bingo.

I believe the 'Before 2' relay energizes when the 2nd ball is lifted...... then there is no ball on that trough sw.
**** Hence you have a play choice before shooting the 2nd ball.
The relay is energized thru contacts 7 & 6 on the Timer......see manual page 29.
likewise relay "Before 3" gets energized when the 3rd ball is lifted ( not shot), and the timer should
have advanced one step to connect contacts 10 & 9.
**** Nick is correct........ you should check that the Timer is advancing, and the trough switches are
switching properly when the balls are lifted.
*** See schematic at location A 18.

All you need is a hand truck and a table cart ......
The table cart is very convenient for moving your bingo inside your house.

Its hard to believe that the 'Spider wipers' were misplaced, since they are on two different sections of the Bingo....
Its more likely the previous owner worked on the Timer and got the wrong part as a replacement.
Its always nice to know the previous owner, but in most cases that is not the norm. He probably couldn't fix the bingo and gave Up on it.
If you don't find the 'Spider", I would try to get another complete Timer unit in case you have
solder issues with the Timer wiring.
Its a learning process.......
**** Just my 2 cents worth. *****

Normally when you work on something, you verify everything lines up and you operate it manually.
Especially in this case where you check the wipers are all in the correct position and the Unit
reset properly. Whoever worked on this previously didn't do a good job.
I would bet the Spot unit wipers are correct, and its just the Timer that is messed up.
Just a Guess......
**** I believe you can unscrew the lock mechanism from inside without trying to ruin the lock.

Ok........ so you have no knowledge of the previous owner.
I'm looking at the wiring location on the unit and it doesn't match the picture in the manual.
The manual shows the wiring on the right side by the large and small holes on the card.
Your wiring is on the left side . So to me the manual and your timer unit don't coincide.
**** Also you have an extra wiper.... maybe that other poster can check his Bingo and see
what is on his unit.

ScreenHunter_203 Mar. 05 18.21 (resized).jpg

We still don't know why the Manual for the Timer doesn't match your Unit.
I'm thinking bally made a modification to this Bingo ( maybe a later version), and you don't have the
latest manual or schematic. Your bingo may be wired correctly but the manual or schematic does not
include the latest modification. That would explain that 7th wiper on the Timer.
I had this problem with one of my bingos and "Baldwit' helped me with that problem.
***** Did you ever verify the ball trough switches are working properly ? They tend to be a problem.
***** If "Xeneize"'s picture of his timer matches your timer, and his Bingo works ok; then I would say
there has been a modification to your 'Miss universe" and you don't have an updated manual or schematic. And, you still have a problem somewhere.

Your steppers are definitely fudging things - you may have some dead bulbs or funky sockets, too. The first image none of the odds are lit, this can happen if the odds units didn't make the initial step. If that happens, there are no credits to be won! So it might have behaved appropriately (for what it expected).
..............................................................................................
Easy job........ I would start by cleaning the Green, Yellow, and Red Scoring Units.
I use fine sand paper and Isopropyl ( 90%) alcohol; just to do small areas if I'm lazy!
Otherwise you can take the wipers off and use a green scrub pad like Keith did in the
video I posted in Post #97.

If I remember I broke the inner black retaining clip off with a large screwdriver. That way you can get
to one side to remove the glass.
You can always buy a new set of locks/key if you want; but since its in your house, I wouldn't
worry about locking it.
It won't be the last time you take out the Backglass to work on something!

That is why I did not recommend drilling it.
What ever works........
*** Nick....... Best wishes.

Just thought I would post something....
Did you ever get the lock open?
**** best wishes ****
