You may have created some new problems doing that, but the kickout problem is likely caused by score motor sw. 4A. so check that for cleanliness and good contact.

And check these circuits for your ball count problem.

Sounds like there's an unreliable connection somewhere in the Coin relay circuit:

I'd check those five switches carefully along with any jones plugs, solder tabs, etc.

Sorry but that was a mistake. This forum is full of posts from people who tried shotgun cleaning & adjustments, and caused more problems than they were originally trying to solve.
What to do instead: Slowly and carefully diagnose one problem at a time and then fix only that.

MarkG is right. Check that circuit with Alligator clip jumper wires.

As the score motor is spinning, does the outhole relay pulse on each revolution or does it engage and latch?

Hi - my first post to Pinside. I'm the person helping Pintor with this machine. I have been a pro audio electronic technician for 30 years, and I have been also servicing Jukeboxes since the 1980s. But Pins are a recent thing for me, and there is so much to learn. The EM machines are especially frustrating to learn on, because of the complexity.

What has been done to the machine so far was indeed necessary. It has sat idle for decades. All of the score reels, features stepper, credit stepper, coin motor ware locked up solid with dried out grease. The EOS blades on 2 of the score reels were broken off and gone. Every contact was black as coal with tarnish. Someone had buggered up the stack switches on a number of relays in the backbox.

After putting everything back together, I successfully played the machine - racking up about 160K points. Everything was working great, that is, until the last ball dropped and game was over. At that point, the machine went into tilt. Would not reset. When I got it to reset, the ball release solenoid no longer fired, and the score motor ran continuously. I confirmed the circuit to the ball release solenoid was good back to the cam switch on the score motor. From there I traced it back to another set of relay contacts ( can't recall which ones now ) I told Pintor that if I had been working on pins as long as I have been doing jukeboxes, that I would know exactly the problem. I wish that was the case. I was tired at that point, so we wrapped it up for the day. He is getting close. I'm confident that there is either an intermittent solder, cracked wire, bad coil causing the problem. I'm sure that is obvious to those of you that are seasoned with these. I have to pour over the schematic soon and trace out the rest of the circuit. But so far, the problem eludes me.

Any insight toward a solution is greatly appreciated. I have a lot to learn.

I would check the make/break on score motor Index-E, and perhaps the rest of these circuits.

Thanks - will do.

Hi Jukester

Welcome to pinside!

Can you have Pintor stop posting endless pictures? They don't add anything to our understanding of what's going on and just make it slower to find relevant posts.

Meanwhile, if the Ball Release coil doesn't activate when the Outhole relay is activated, inspect and diagnose this circuit with Alligator clip jumper wires.

Thanks Howard. The problem I believe is somewhere after the outhole relay. I traced the the blue white circuit back to the C 4 score motor stack, then the grey green circuit back to the outhole relay. I didn't have time to dig farther. but up to there it's solid. The red side of the Ball release solenoid shares the circuit with the flipper solenoids - and those work fine. So I have to just keep digging until I find something. Thanks
