Hello everyone! Firstly thanks so much to anyone who's already helped me on this machine prior. I'm brand new to EM pinball and I can't tell you the confidence you folks have already given me to fixing my own machine. Without your help I wouldn't be as far as I am already. Thanks so much.

I have several issues that have occurred in my game and I was curious if anyone could offer a suggestion.

1) (and I think I'll just start here because it's the most annoying) I have a loud buzzing sound that continues throughout all play of the game. I'm not entirely where the buzz is coming from but it's not like a hum or electrical sound. It's a purposeful buzz that typically in the game just sounds (I believe) when the ball rolls over the two rollover targets that changes points to 100 to 1,000 points during game play.

2) My game typically upon starting a game with kick out the first ball but will fail to kick out the next ball for the next game.

Here's my schematic. https://images.pinside.com/f/11/b5/f11b5fb1e63f1b7998e72535a1b7bad9d162ef9c.pdf

I'm super knew to this but I do have a deep desire to learn how to work on em machines.

Thanks so much for any information anyone could provide. How do I stop this sound!!

Thanks so much for this tip! I’ll do right when I get home.

Would you say this under the play field?

Ok found the change relay . It doesn’t sound like that’s we’re the the sounds coming from. It actually sounds like it’s coming from the first player drum unit (score reel) in the back box. Certainly sound like that’s we’re the soundbis the most intense.

However with that said what does the schematic say what the switches should be doing? Closed or open on the change relay?

Thanks so much everyone!!

Also I’d more than happy to take a video so you can hear that sound and where I think it’s coming from.

Furthermore it really seems like the buzzing is coming from the relay coil on the 1000 point reel in the machine. I pulled out the reel and the bracket holding on the relay was super hot. Way more than the other brackets over the other relays on the score reels.

Thoughts?

Can you tell from the schematic if the 1000 point relay switches are supposed to be opened or closed?

Also what’s strange is the score reel cycles through and gets to zero and then the buzzing starts.

It fixed the buzz!! I did have a blade out of whack on the outline!! Thanks so much

Any advice on checking c1 on the score motor? What’s the switch supposed to be doing?

Thanks so much. I hope I can type this next question clearly in a way that makes sense. How do I look at the score motor on my machine. Do I face it at the top of the machine by the flippers. I'm having a hard time knowing which direction I'm supposed to be facing to make it match the chart.

So when I'm looking at the game from the front of the game (at where the flippers are) right in front of me should be stack A?

Ok I found it. It was already open so I took a file and started cleaning the switch. However it’s still not fixing the problem. Actually now when the game starts the ball doesn’t kick out at all. It used to kick out on the first ball and none on the other balls. Any other thoughts? Is It possible I don’t have it clean enough? Or is it possible there’s something wrong with the coil?

What does jumper it mean? Still in the process of learning all the lingo.

The score reel cycles through like normal and stops with no ball kicking out.

Hey everyone thanks for the help on this. I’ve recently stopped working on this out of fear I was making the problems worse but now we all have a ton more time at home!

Any ways can anyone look at the schematic and see Whitehall switch controls the motor running? Now whenever I push for a new game the motor keeps moving cycling through without stopping.

Any thoughts?

Thank you! Judging from looking at this would you say these switches are on the cam?

Ok great! I see what you guys are talking about. Question then on understanding reading the schematic. On here I see that it’s indicating that the switch needs to be opened and so forth but when I look at the relay I see up to four switches to that one relay. Does it mean they all need to be open?

What does change state together mean?

Ok so I got the game to stop cycling but now the game won’t motor through at I got the start button (basically I push it and nothing happens.)

I’m suspecting the culprit is the “a” switches on cam one. I see that a1 is supposed to start the motor. Here’s a picture of the a switches,what they control, and what my switches like.

To me the outlet contacts don’t appear to be making proper contact.

What’s your guys opinion? Am I off the track?

Good morning everyone! Hope everyone is well and healthy. First thanks everyone for helping me. Is there a chance someone could help me?

I’m now in a situation where my Game has been down since December. Right now when I push the start button the motor doesn’t start to start a new game. Could someone look at the schematic and tell me which switch starts a new game?

Thanks anyone fir any information!

Ok update! I just adjusted c4 on the first cam and now the motor runs but it doesn’t stop. It just keeps going! This is progress! Any suggestions?

First off thanks so much for always trying to help! To me it seems like A1 on the first cam. It seems like the smallest adjustment is what makes it turn on and unfortunately for me right now it doesn’t stop running. For what ever reason it has stopped again after another adjustment.

Now this picture of the schematic you sent I’m not sure I see where it is under the play field. I do see a collection of switches over a coil I believe that says start relay. Is this where I should be look as opposed to the cam switches?

I’ll send three pictures of what I’m talking about. Is

I’ve recently had something weird pop up. I’ve recently had the game serviced and it was working great. Sadly out of no where the game has started doing this thing where it’s like forever starting. The drop targets keep trying to re pop up. Any thoughts on what I should check?
