Hello,
First post. I have a Bally Amigo. I have owned it for 8 years been tinkering and learning little by little. I have an issue that I am just stuck on. In multi player, 2,3 or 4. For ball 1 all players no issues, after the final players ball for the round whether that’s 2nd, 3rd or 4th, drains it is switching to ball 2 then 3 and staying on the last player till game over. Player 1 works with no issues. The game resets normally. I have cleaned and cleaned and I just don’t know where to look for this issue. I do have schematics but I don’t understand how to read them very well.

MarkG yes that is correct the ball count increases to ball 2 and 3 but remains on the last player. So after player 4 for example drains their ball, it goes to ball 2 still on player 4, then when that ball drains it becomes ball 3 player 4 then game over.

I will see what I can determine of that EOS switch you have highlighted for me tomorrow. I am not real good at these things in this regard however. I’ll get back to you soon

ArgosySK i honestly can’t decipher which relay is the player reset relay? Any ideas? I’ve clicked all the relays and I identified the one that triggers the next up player from 1-4 but not the one that resets it back to one? The unit does rest with the game reset and start up sequence so I know it works just the in play has some issue holding it up? Again I am new to this and I just stuck here. Everything else to this point has been new bulbs, new rubbers, and cleaning gummed up units and then this issue popped up.....any help appreciated

MarkG j am lost as to what this eos switch looks like and how to properly ascertain if it’s functioning correctly? And tips to help a noob out? I did check all the switches and ran some sand paper between them to shine them up but beyond that I am lost

They unfortunately are not labeled.....some are but most aren’t and none of the labeled are the player reset. I have 2 identified from manually triggering them that do nothing that I can tell.

Ok so when I advance the ball count plunger a relay clicks. I’ve identified it. It has the orange red wires and yellow you mentioned. So where do I proceed from here now?

When I manually advance the ball count unit, it does trigger this relay I added a picture of. But nothing else happens....

Mopar MarkG ArgosySK ok, sorry it’s taken some time to get around to testing theories. So here is what I have done first I lightly sanded every contact in the game. After playing around, on the player reset relay specifically. It fires as it should when it should. Nothing happens but when I jumper it from the first set of switches which is a make break, to the second switch which is a normally open switch. I am doing this which the solenoid energized which then makes the second set of switches closed voila the player will reset to player 1. Now my noob question is: how do I fix this? The points are making contact, they are all clean and touch when they should when it’s energized but the electricity is not making it where it needs to go? Also all the solders are tight and protected with plastic shrouds. I appreciate everyone’s help! Pictures of the switch in its different states 1st pic the switch not energized, 2nd pic energized, 3rd pic is where if I am jumpering/shorting it with a screw driver it activates the player up disc back to player 1. I took the third pic without it energized as I simply don’t have enough hands.

Just to add to this. If I leave it with a jumper between these two, the game will not switch out of player 1.....

ArgosySK thanks, yes when the eos is activated the coil on the player reset relay also activates it was doing that before I shorted the switches to get it to activate the reset coil on the player up disc though

Rikoshay i actually did do continuity testing but suffice to say it was brief. I’ll be sure to do some more testing this way tomorrow and hopefully get back to you thanks for the tip and I’ll explore this rabbit hole for sure!
Mopar great suggestion as I have admitted to I am terrible with schematics and that score motor cam looks to be a treacherous thing. I will try to identify this switch on cam 1 tomorrow as well and explore it hopefully getting back to you tomorrow! Thanks again for everything!

Mopar Here is a picture of score motor cam in test position and then when the cam is rotating. Do you see any issues? I haven’t continuity tested it yet.

Mopar alright so when I manually make the cam do it’s rotation the player reset relay is not being activated by that process. There is one wire I can see that is present on the player reset relay and also in the stack of switches in that stack on cam position 1 it’s a blue with orange stripes.

Mopar ok I reinstalled and plugged in the play field. I hit the ball drain out hole hole. It triggered the cam which did trigger the player reset relay for a second or so. I did a quick 2 player run through by manually hitting targets and the outhole. Player one end. Player 2 up no problem, player 2 end went to player 2 ball 2, reset relay was triggered just didn’t reset to player 1, then after another manual point and manual outhole it did go to player 1 ball 3. It has done this a few times since this issue presented. So I am just confounded and confused. What should I be lookin go at? Seems like a broken wire or solder but they all appear tight.....ugh

Mopar sorry it’s taken some time getting back. On the cam I thoroughly cleaned each contact and tightened the switch stacks. On the player reset relay I also cleaned the contacts and verified contact is being made (visually) and I tightened the screws holding the stacks there as well, while testing the game actually swapped back to player 1 after player 2 ball drain, but then for ball 3 reverted back to the original skipped player 1 and continued to ball 3 player 2. Then has since gone to its original form only switched back once. Any ideas where to go from here? The player reset relay btw it grabs and holds for a solid second or 2 so I feel that’s all doing it’s job correctly. Is there a switch somewhere that sends the power pulse through the closed switches on the player reset relay when it’s activated that maybe is not sending the power pulse to activate that reset solenoid? Hopefully that makes sense? I am asking because the shirt I did that does make it operate is merely sending a power pulse so I guess it seems like everything’s working but somewhere that power pulse is not make it’s way to the solenoid to activate it.

ArgosySK ok, so I thought it was making good contact, but I gave it the slightest bend and that fixed the issue!

However no good deed goes unpunished.....immediately after 2 new seemingly unrelated issues popped up.....

First and biggest issue....now when I reset the game, the normal reset sequence goes into affect. However now the reset relay for the right side of the game, players 2 and 4. That relay pulses in and holds instead of pulsing and releasing to reset all the score reels on that side of the game. Any thoughts here? It’s score reset #2 pictured below.

2nd issue player 4’s scoring is off...seems to be every 3rd 1000 pt target hit the score reels adds 10,000 points but it’s not reliably every 3rd target....oh my what a mess. Any help as always I appreciate everyone’s hard work and thoughts!

As an edit if I use a screwdriver and manually break the contact on the #2 relay and force it to pulse that does reset the game to all zeros and the reset sequence stops.

ArgosySK OMG! You are literally my hero! That link helped immensely! That was exactly where that problem was! Thanks a literal billion!

Now lol one last issue has popped up. No surprise I poked around but could seem to isolate where this one is either. Now when the ball lands in the 3k point kick out hole top center, it’s making a buzzing sound from the bonus step up disc beneath the play field but the scoring is erratic from just that hole. Sometimes 2k, sometimes 4K and generally 50% of the time it scores correctly at 3k same issue across all players. Any thoughts on where this one might be?

ArgosySK Resolved! Your the master! It was the gap on the 9a cam motor switch stack. Increased the gap and problem solved!

Now the last issue, the one I have actually had since the game first became functional as I have worked and learned on it across the years.....it’s very minor but hey why not get it 100% right?

So player 1 ball 1 whether in single player mode or 2,3, or 4 player. The initial 1k pt light on the bonus tree is not active (pictures below) the score reflects it too. Every other players ball 1 begins with the 1k bonus activated. (Also pictured below and I am pointing to the issue in both with the back glass visible for reference).

I am seriously so happy and so thankful for all your help!

ArgosySK assuming in my inexperience here that 7c would be the third leaf switch from the top of the stack? If so 2b is open and 7c is also open. I held 7c closed with a screwdriver during a reset sequence and it didn’t make any difference. Maybe I am not fully understanding?

ArgosySK if I trigger a tilt on ball 1, then drain the ball outhole switch, it goes to ball2 and the 1k pt bonus is pre lit.

Mopar tha is for the insight!

ArgosySK so are we talking an issue with the main reset relay for the entire game or an issue with the reset relay for the bonus stepper unit? Any ideas to pinpoint?

ArgosySK so unless I am eyeing it incorrectly the bonus stepper unit has completed its reset process and then the outhole kicks the ball as the last step. So the relay pulls completed its job then the ball is locked out

Argos I believe it pulls, I am not entirely sure I am looking at the right thing? Is the relay on the stepper unit itself, or is it on the row of relays across the floor of the body? Identifying which one it is without labels has been difficult. The stepper unit completes all its click and then the ball kick out kicks the ball out.

So I believe this is the bonus relay reset? If it is on start when the game resets this does not pull in during the start up sequence. It does pull in on ball 1 player 2 and illuminates the 1k pt light in question here. I hope this helps clear things up? Sorry I am still very much learning here...
