You would need to find the circuits that send power to the 100 point score reel and the 10 point score reel. Most likely, power is not getting to the 100 point relay and the 10 point relay during those points in the game. Do you have a schematic for the machine?

one explanation of the resistors is "preheating the coils of AA-, BX-, CC- and DD-Relay(s)" - make them react faster.
another explanation is "suppressing sparks on the Balls Played Unit".
Once Your problems are fixed You may try: Unsolder one of the resistors - then watch the unit when it steps --- do You see on the one step "no more having the resistor" spark(s) ?

Bring Your pin in "Player-4 is playing Ball-5" - then a friend manually makes 10 points on the Playfield - YOU watch the M-10-Point-Relay - big question: Does the M-Relay actuate ? (The M-Relay probably is mounted in the Baxkbox.) Greetings Rolf

Well, it's been a while on this thread, but I have a somewhat similar issue, so here goes:

Game - Happy Clown

Status - got her all cleaned up and working - but two issues:

1) - Balls Played Unit - When a ball drains, the two switches under the playfield activate correctly (ball drain and lifter to allow the ball to be played again..sorry, do not know the correct terms/names here), the "BPU/Change Player" relay activates, the score motor turns (I've checked the switches which appear to be making / breaking correctly) - but the BPU itself does not fire/move what so ever...nuttin. I can manually step the BPU, but even tho it's on one Player, it steps to the next player, balls 1 thru ball 5 - then stops....so it looks like the stepper is working, but not getting a signal from the score motor to activate?

2) Player 1 only - 10's score reel does not roll over the 100's at all. I've checked/cleaned the 9's position switch, but again, nuttin All other players work correctly.

Any ideas ? All help is appreciated. Thanks!

In reference to my last post - Score motor switches verified:

1A - 2nd
1D- 1st (inside)

2B - 3rd
2C-5th

Maybe I'm missing one..or two? Just not getting signal to the BPU??? Or so it seems...

And here are photos of the two switches and the relay I was also referring to I’d that helps ?

If the 100 Point relay (Q) doesn't activate when this happens Inspect and diagnose this circuit with Alligator clip jumper wires

If the Add Balls Played Unit solenoid doesn't get power when the ball drains, Inspect and diagnose this circuit with Alligator clip jumper wires

Will do this evening, thanks again HowardR! I'll let you know what I find out

It was a blade on the BX relay not normally closed. Now it’s stepping thru the balls ok. And for a few it also started rolling the 10’s over to the 100’s. Thought the same issue caused the same problem for a second there.

Back to the score reel...almost there thanks HowardR!

Well I thought I had it. Slightly adjusted one blade in the “M” relay. And was getting it to roll over. But then it would roll over almost every Time the 10’s were activated. So I re-opened that and I can’t get it to work in any fashion now. Even tried to close it again and it’s just not working (don’t think it was supposed to be closed anyhow)

Question HowardR- how / where would I jump for this one ? Especially on the BPU?

Did you read the links I posted?

Read yes. Understood thoroughly no. I see using the jumpers to possibly determine which switch may not be working correctly but not sure on where to place the jumpers?

I’ll review again today and see if it gets clearer.

If you'd like to try a phone call, send me your cellphone number in a private message and I'll make a first reply with a text message

Howard you’re a big help. Let me get home (in Oregon right now) but later in the week I may take you up on that !

“HowardR” - Sorry this one skipped past me. Turned out it was the 9’s switch on the 10’s reel. I had adjusted that I know 3 times. It was working fine. Then it started acting up again. Looked once more and it wasn’t always making contact. Fixed! Thanks again !
