Machine was in shambles paid 100$ back glass and playfully are decent, after 4 hours I have the pinball machine playing well for the most part except ball count stepper is not resetting from 5, I have to open play field and rotate the fingers back to one which is s pain counts up no problem just does not want to go to zero from five. Game will end and restart with start button but will be stuck on five, I do not know if it is lever not lubed properly because I think it wouldn't count up if that was the case, SOMEONE please help. Last time I work on a pinball machine was thirtern years ago when I was thirteen and found a bally four queens in the woods wrapped in a tarp at my neighbors house he said " if you can move it you can have it " my skills are rusty at best! No schematics:(thanks in advance

Hi Anthonyb
I have never seen the inside of a Chicago Coin Pin. You do not have a schema - we might have to look at the schema of "Skyrider" http://www.ipdb.org/machine.cgi?id=2201 .
Maybe the "Problem on Ball Count Unit" is mechanical, lets have a look at the Manual of "Jukebox": http://www.ipdb.org/machine.cgi?id=1324 -> Parts Manual: http://mirror2.ipdb.org/files/1324/Jukebox.pdf -> page-25.

The "Ball Count Unit" is a "Total-Reset Stepper". There is (hard) work to do when stepping up - Coil (26) moves plunger (28) - against the pulling force of "Spring (3). The Coil let go and "SPRING (3) does the WORK, the step-up.
When the Unit shall (be) reset: The Reset-coil (11) pulls and move an arm to un-latch so the reel (25) "whoaaaamm" the reel is turned counterclockwise (down to 0/1). This work is done by the SPRING mounted on the axis. In the picture: Arrow-34 points to "End-of-Spring hooked-on".
You might detach the spring there and twist the "End of spring" a full circle around (counterclockwise, tighten) and mount the "End of spring" at the same place.

I SUGGEST - FIRST try: Manually step up 1 -> 2 -> 3 -> 4 -> 5. Then imitate "Reset-Coil starts pulling" - You Yourself move plunger (8) -> Question: "AAA" the Unit does reset ("whoaaaamm"), "BBB" the Unit does not reset.

If the answer is "BBB": You can try "Tighten the spring (34) and / or cleaning.
If the answer is "AAA": We have to look for "Why does the Reset-Coil not fire". Greetings Rolf

What you just said to me makes very little sense at this current moment as I just woke up, but in approx. Three hours I will have studied this. I and will have mastered Rolf's directions. I will be in my shop until 5:30 pm after that will go home and get to the machine and give all of this a shot, I really appreciate you replying promptly thank you! - Anthony

What do you mean by “rotate the fingers back”? I wouldn’t think you could not be able to do that, without manually firing the reset coil.
Can you post a picture of both sides please.

Galaxian,
You wouldn't have the back box metal door by any chance? I have a Juke Box missing this. I assume they would be the same size?
