Hi. Have a Jumping Jack that won't start. Every once in a great while pressing start will cause motor to turn and stop but reset process never occurs. Score reels do not move or even attempt to move. (They will move once playing a ball) At power on game shows game over and tilt. If I press start relay I get same thing as when start button actually registers. I can manually move the long bar that controls reset relay bank and get game to play (after manually pushing tilt hold relay). It goes to a 2 player game automatically. Also game stays at player 1 ball 1 infinitely. I can manually press stepper in head to get game to progress. Another thing I noticed is some 10 point switches will only score when lit for 50 points. (Maybe a setting? Those points setting plugs never make any sense to me). Nothing happens on its own essentially. I will say this game is pretty damn clean inside. Steppers move nice and smooth. The only other stepper is the bonus stepper under the playfield that I could find anyway. Both are continuous steppers. Oh there is the credit wheel too which seems to function correctly. Ideas? Also...does this game have a switch stack chart (NO,NC,etc)? Can anyone send me pics if they have access to it? Thanks guys!

After looking at my pics the top switch on the right side of the motor looks off doesn't it? I will look at that tomorrow.

If anyone has a switch stack chart could you email me a copy? Gonna dig back in next warm day we have...want all the info I can gather. Thanks!

Thanks for all the info so far guys! I will report back.

Yeah the chimes are missing. Will definitely replace them if I can get running. After messing around with it today the HOLD relay no longer gets pulled in. Can no longer manually start a game by manually pressing reset bar. Ideas on this?

Before this happened.
Pressing start almost always did nothing. If it did anything the motor would move to next spot and stop and credit would come off the wheel (game would stay in tilt until I manually released tilt hold relay). Same thing when I press start relay...motor moves to next position and stops. Score reels will not reset no matter what I try. They will score though. The only way I could get playfield to come to life so I could play was manually pressing in reset bar. Once I could play it would not advance player or balls. Bonus stepper and drops and pops and flippers and outhole and kick out holes all seemed to work fine at this point. If I manually actuated the player stepper it would change players and balls. Game would never end though. The game just won't do anything on its own. Most things seemed to work once manually activated. The game will never come out of tilt unless I manually press tilt hold relay.

Like I said earlier now hold relay is not activating and I can no longer start a game even manually...

So I just read that the tilt switches can cause hold relay to not work. I was messing with tilt switches when this happened. Have to look at them again. I have read start up sequence many many times. The start button doesn't do anything most of the time and start relay doesn't either...So I guess the problem is there or at least starts there? Or is the game not coming out of tilt on its own the issue?

Does anyone have time to walk me through how to do this?

Alright I will try the alligator clip method. Will this work through the insulation of the wire? Dumb question? Lol...

Attached jumper wire from orange wires on start switch to red and black wire on fuse near bounce switch. Turn game on and no change. Stays in tilt, game over. Manually push in tilt hold relay, lights on playfield come on start switch still does nothing. Manually push in hold relay (which then stays locked on) and start switch still does nothing.

What should I try next? I wish I could get the startup sequence going. Can't do anything else until it starts! Is it a given that my problem lies under the playfield and not on the playfield or in the head? Please any ideas you have no matter how unlikely I am willing to try. Thanks!

I will also mention for whatever it's worth that if I manually push in the reset relay bar I can press the start button and the motor will turn one rotation.

Also some 10 point switches won't score correctly. Could one of these be my issue? The same 10 point switches that score when lit for 500 will not score for 50 when unlit.

Could relay C be causing the scoring and startup issue?

Hi. Sorry wasn't ignoring your advice. I have read through it many times. I am not very good at reading schematics so I am having trouble knowing exactly what to do with that info.

I thought that's what I was doing in post 22...did I not do it correctly? Lol.

Haha...figures...this one then?

1519192578021609302270 (resized).jpg

Oops. Just saw your post...I will try that one.

On the left?

1519193359037419099266 (resized).jpg

Still a no go. Tested with my meter and have continuity between that fuse and the orange wire on start button.

This may or may not mean anything but I have continuity from start switch to several relays too. Outhole, start, tilt hold, hold, several reset bar relays, NOT game over or 2nd player relay.

Found a broken wire on left hole relay. What's weird is that the kick out hole still worked... I will solder this back tomorrow. Any chance this fixes my issue?

Looks to be a white with purple wire.

1519195354581548906637 (resized).jpg

Thanks! I will report back.

Where is the v coil?

Press start relay and hold relay pulls. Stays in tilt. Press tilt hold relay and comes out of tilt. Press control bank relay and reset bar coil fires and starts a game. Score reels do not attempt to reset but drops reset and playfield comes alive. Then when I press start it actually works and subtracts a credit off the wheel.

A lot of repetition in my posts I know just want to share what I am seeing.

Just noticed activating the coin drop switches activates start relay and motor and hold relay and credit wheel but nothing else happens.

Pics of my reset bank.

See the far right relay? The left switch is closed on both sides and looks like only one side would open (front side) when activated. Should the back side be open when front is closed? It shouldn't always be closed or why would there be a switch right?

If I reset relay bank bar by hand then turn on...
1. The game over relay QB energizes.
2. The start button will work and when pressed one time the 2nd player relay PB energizes.
That's it. Nothing else happens.
Stays in game over and tilt. No reset process occurs or even tries to.

Just noticed that the game over relay is constantly energized. From the moment I turn it on. If I reset when off it energizes when powered on. If I try to reset when powered on it just stays energized and buzzes at me angrily...

Alright so measured resistance across all the coils in the reset bank relay and all are 3.5 to 4 ohms...EXCEPT QB and ZB at 0.5 ohms...those 2 coils are shorted right? Please tell me this could be my issue?

I don't think ZB has ever actuated. I will check on this and see what QB does when I do these things. I will report back tomorrow. Thanks for your time!

Power on and QB actuates. ZB does not. Pressed start and motor turned once and bonus stepper under the playfield reset. Hold relay is on game is in tilt. I manually actuate tilt hold relay and it stays actuated. I manually press control bank relay and QB is released. So apparently QB is functioning correctly? At this point it appears nothing is actuated on the reset bank at all...pic is of reset bank at this stage.

So what are we thinking? Should ZB be actuated at this point? Could THAT be the issue?

15197926010281709027901 (resized).jpg

Also I pressed start again and PB actuated. ZB is still not actuated...

So I manually actuated the ZB relay when powered off. Turned on and game actually tried to reset. The motor kept turning and the AX relay in the head kept turning round and round...At this point SB2, SB1, QB, ZB, LB are all actuated while AX and motor are constantly spinning.

So some times it does what I said above and sometimes the reset bar will reset everything (except score reels which never even try to reset).

No matter what the game will never advance from player 1 ball 1.

When I do exactly as you described....
Game resets to player 1 ball 1.
Playfield gets power and ball is ejected.
Game will score points.
When ball drains it stays on player 1 ball 1.

During a game no relays on reset bank are actuated.

ZB never actuates. Even after points are scored.

Just wanted to you are AWESOME for taking the time to help me out. I really appreciate it. I will try what you said and report back tomorrow. Thanks!

When I do as you say above...QB will actuate when powered on. ZB does not actuate.

I turned on game and QB actuates but ZB does not...so I manually actuated the ZB relay after starting a game...score points...drain ball now moves to ball 2...repeat process ball 3 etc...(the whole time ZB stays actuated)...when ball 4 drains the game makes a horrible buzzing sound as LB actuates but ZB won't release. Turned off and on and both relays still actuated (along with QB).

ZB has to be the issue! Right?

How do I go about trouble shooting WHY ZB won't actuate on its own? Motor switches? Wiring? Shorted coil? SB armature(this game have one?)

Couldn't get a great pic but ZB is the only coil that is toasty brown where it should be white on the end . All the other coils are white.

20180320_224615 (resized).jpg

I am so bad with this. When you have time could you let me know where to place each side of the jumper. Maybe using one of my pics? What do you think about the toasty coil ZB?

2 more reminders in case it somehow means something...Score reels NEVER reset...some switches (50 points I believe) cause motor to turn but points are NEVER added for 50 points relay.

Did some re-reading and it looks like score reels should be reset after ZB is activated.

1. ZB coil is toasty. Tests at 0.5 ohms.
2. ZB never actuates.
3. Score reels never reset.

Would ordering a new coil for ZB be a good idea? I need to order another coil for a different game anyway. Also need new rubber for this one...

This is what I do to get the game to start. Activate (plunge) ZB while power is off then power on. But the score reels will not reset, they do not even try. Ball kicks out player 1 ball 1. That is where it stays. Points will score and bonus will count down when ball drains. If I manually activate (plunge) ZB again then the game will advance to ball 2, ball 3, ball 4, then drain and get buzzing sound.

So could ZB bad coil be the cause of my problems or just a symptom of another problem?

When a 50 point switch is activated the score motor will turn but points will not score. Problem with the C relay? (50/3000 point relay)

The eject holes seem to function fine and score correctly when lit. No buzzing.

Any additional help is welcome. Anything you have to offer I would greatly appreciate.

Progress!

I replaced the ZB coil and sure enough the original coil was bad. Now when I power on the game QB and ZB actuate. Then I press start and both SB1 and SB2 actuate. The motor then just keeps spinning around and the AX relay in the head just keeps spinning around. It does this forever until I turn the game off.

So the score reels still do not try to reset (Maybe this doesn't happen until we get past where my game is currently stuck? ).

I checked the AX switch and I think it is working correctly. It alternates open and closed with each actuation. I cleaned it's Jones plugs too.

Under what circumstances does AX constantly spin around? What should I look at or try next?

Apparently my AX relay is known as an AS stepper...

Screenshot_20180330-005509 (resized).png

Also found this...

Screenshot_20180330-010831 (resized).png

And this...remember my game won't score 50 points (drop targets won't score for example).

Screenshot_20180330-012001 (resized).png

I manually stepped the player stepper and AX relay stopped spinning. It did not start spinning on it's own but eventually it kicked out a ball. Player 1 ball 1. It does progress through ball 2, 3, 4, when it gets to 5...LB relay is pulled in and a horrible buzzing sound occurs.

I tried several times starting new games. One time the motor just kept running and I let it go for a while and noticed that the player unit was trying to move but the coil was barely pulling the plunger in. After a while it moved one or two spaces...

The score reels will still not reset or even try...

One thing to note is that sometimes when I powered on the game LB would instantly pull in and I would get that horrible buzzing sound.

It sounds like it is coming from LB or ZB. Somewhere in there. When it happens I turn it off real quick so nothing burns up.

I adjusted the switch on LB and the buzzing stopped! Thanks for your help on that one. I was able to play a game from start to finish for the 1st time. Of course I had to manually step the stepper in the head until it reset the pin and kicked a ball out. And of course the score reel is not reseting.

I am going to read through this a few more times and try to dig in. Hopefully a dirty misadjusted switch or broken wire. Thank you so much for all of your help so far!

We are getting closer! So SB1 was not making good contact when plunged. Adjusted it and here is what we get now...

Press start stepper in head and motor run. Thousands place of score reel resets. Then startup process stops as ax relay spins round and round. I manually plunge the stepper in head just once and it completes startup sequence (except score does NOT finish resetting) and kicks ball 1 out ready to play.

So...
1. Thousands score reel resets. Others do not.
2. Startup stops at ax relay spinning round and round.

Little more fiddling and now the tens and thousands reset on player 1 and all reels reset on player 2.

Feel like we are close.

So what switch or step is supposed to happen to reset 10 thousands and hundreds reels?

If I set 10 thousands and 100s to zero position game starts right up! So close! It's killing me...lol.

I just don't know what to look at next...motor, player stepper, or what.

The player unit stepper stops after tens and thousands are reset on player 1. Then AX relay just spins. One manual push of player unit stepper lets game finish resetting (except 100s and 10000s score reels for player 1) and kick out ball 1 ready to play.

So from the highlighted schematics the problem could be score motor switches 1A or 4A? I see a blue spark at what I believe is 1A. I tried cleaning with flex stone and adjusting gap to be closer...no change so far.

What/where are those other switches? (Runout switches and P switches)

And does this apply if player 2 resets just fine? Could the problem be in the reels themselves? Zero and Nine switches seem to be functioning correctly.

It works! I adjusted the runout switches and it starts and plays all the way through!!! Whooooooooo! Thank you Howard and Rolf for all of your time and help!!!

Next task...scoring issue. This seems to be the only issue left. The 50/3000 relay doesn't seem to pull in long enough to score 50 points on rollover switches and for drop targets...it will sometimes score 10 points and sometimes not score at all. The 3000 point switches work fine (kick outs).

The motor always turns. Just no points/not enough points. When I look at 10 point relay in head it barely pulls in when activating the 50 point switches.

I tried adjusting the 50/3000 point relay it went from no points...adjusted it...to locking on and not releasing...adjusted it...to scoring maybe 10 points then releasing.

Where do I start?

Sorry was tired last night...haha. It is the C relay. 50/3000. Edited previous post.

One clip on C coil? And other on motor 2B switch? Is that right?

So I read those articles a few times. One clip to C coil on left side of the coil (looking at schematic the side opposite of mar-yellow wire) and other clip to side of 2B that is opposite yellow-green wire. Is that right? I am really not good at deciphering schematics.

Or does one clip stay on the red and white wire like the article states? Does that apply to my relay too?

Reflowed solder on coil C. No change. Tightened switch stacks and now relay stays pulled in for motor rotation...BUT still no 50 points and now 3000 points won't score. There are only 4 switches on this relay...how hard can this be?!

Which switch does what on this relay? Best way to adjust?

Holy hell I got it! The switches on C needed adjusted. Wow there is like zero tolerance for gap errors on this thing. Working all the way! Thanks to everyone who has helped me along the way. Now on to painting!

Ok. Sorry it appears I have another question...Haha. Played several games and never really looked at the rules before. It appears as though hitting the last of 10 drops on a single ball should award either extra ball or special depending on what is currently lit. My game doesn't appear to be doing either. Ideas?

Going to be looking at the drop target series switch in the middle of the drops and all the other drop switches tomorrow. Any other ideas are welcome.

Targets score bonus and come back up. Just won't award extra ball or special.

I will check it out tonight. Thanks guys!

Man ... I am having a tough time with this one. I have looked at A, E, F, BX, 4E, 1C, drops series switch (it appears one side is for starting bonus countdown, I guess the other side tells machine to award extra ball or replay?). It was set to medium ( the replay award) conservative seems to alternate between extra ball and replay at the same rate as medium for some reason. It is currently at liberal. Under no circumstances has the award ever been awarded. I tried following wires on the schematics. I just can't really make sense of it. Can someone tell me what other relays, motor switches, stepper switches to check? If I leave in liberal mode?

Just to be clear the award lights are lit and alternating correctly when playing. It is after all 10 targets are dropped that the actual extra ball and extra ball light and replay award are what I am not getting.

When I manually close the top of 2 switches on drop series switches the bonus countdown occurs. When I manually close the bottom switch nothing happens at all...I feel like it should?

You know I think the drops are supposed to be worth 500 points after knocking them all down the 1st time...That doesn't happen either...the 500 point light doesn't light up. I assume this is somehow related.

I have it set to liberal. The lights for extra ball and special alternate correctly. 50/50.

Just not actually getting the reward once all 10 drops fall. Get drop target bonus...no extra ball or special. Also after hitting all drops and they reset...the points for drops stay at 50 instead of going to 500.

G relay does not activate. So that is for 500 points per drop. Will check that out this evening. Thanks!

Thanks Howard! Adjusting F relay fixed it! Game now plays fantastic! Chimes came in the mail today so sounds great too! New backglass should be here Tuesday then paint cabinet and new rubbers, clean, wax...

The one and only issue left...match numbers don't seem to be lighting. Now could be all those bulbs are out (not likely) or maybe a setting? Ideas?

I would attach jumper during game over right?

Got it! It was the back switch on XB relay not closing all the way. Thanks so much for all of your help Howard! You are a great asset to the pinball community!

I even figured out the points plugs in the head and matched the score card to award 3 free games based on what the score card states.

Yeah so it appears I have yet another (albeit minor) issue...Where it shows 1 or 2 players on bottom right of glass...it seems to stay on 1 player until end of game (even a 2 player game) and then at game over seems to at least most of the time light 2 players...where should I be looking?

I am not even sure what the correct functions of the 1 or 2 players light is. Alternating or 1 player or 2 player lit depending on 1 or 2 player game?

I feel like someone at some point in the past just went in and started bending switches any which way just for spite!

It was indeed the back switch on PB! Thank you! Unfortunately I have found another issue...never ending it would seem. The far right 3 drops only intermittently score bonus when ball drains. I spent probably 2 hours trying to adjust the switches (the ones in front of the drops that stay closed when target drops and lights 100. I could get them to work more often than not when playfield was lifted but as soon as I lowered the playfield they would not score the bonus the majority of the time. If I pushed hard the switch together with a wood rod while ball was draining I could get bonus to score on right 3 drops. Problem is if I adjusted them any closer (already way closer than the other drops) the switch would be closed when it should be open. I also just for fun widened the gap far apart like the other drops and no joy. I tried tightening the screws on the stacks the ones near the blades I could get to but not really the other screws away from the blades. I even tried making a sort of u shape for extra tension when closing...no improvement. Am I going about this the wrong way? Oh Hell I just thought of this...could it be a dirty bonus stepper?!

Grrrr...I bet it is the bonus stepper. I once replaced tons of what I thought were faulty light sockets and it was a dirty stepper!

There is probably a rivet for each drop target right? Probably an intermittent connection due to dirt or misalignment? Am I on the right track here?

I got the last 3 drops scoring bonus correctly! It was the runout switch for the bonus stepper (didn't even know there was one until I studied the schematics). It was gapped too wide and was opening before drops 8 to 10 could score bonus (they score last...right before runout switch opens). ENORMOUS thanks to Howard who took the time to teach me about reading schematics earlier today over the phone!!! He helped me narrow it down to the bonus stepper. You have seen me post this before but I think it is finally time to move on to painting, cleaning, waxing, rubbers (the "easy stuff"...lol). My new glass is coming tomorrow (redelivery as I was out of town the 1st time). Thanks again to everyone who has chimed in along the way. I hope this thread helps someone in the future.
