My Williams Star Pool was playing really well. Now for some reason every time the spinner is hit then another 10 point target is hit it completely resets the machine back to 0 and the ball release coil reacts as if a new game is starting. The spinner has to actually be spinning when this occurs. I can't get it to do the same thing while other targets are being activated. Any help???? Thanks.

New development...maybe related?

I've noticed that the 100 point reel is not being activated by the 10 point reel as it should. I manually pressed the 10 point relay and the 100 relay never moves. I tried this on all four players and the results are the same. It simply keeps moving through 10's and never causes the 100 pt reel to move.

I tested continuity across the switch on the 10 point relay that pulses the 100 point relay and I'm getting continuity when the switch closes. Anyone know the next step in tracking down the reason the 100 point relay is not getting pulsed?

I'm starting to believe there is a short and it has something to do with the 10 point relay......

Here's what's happening: (remember this thing was working great 2 days ago)
Player number 1, score reel will not energize the 100 pt reel when on the 9 switch. I've clean the switches and check to see that they are working correctly, still just keeps giving 10 points and not scoring up to 100.

Player number 2, same as player 1 except will finally begin scoring up. After a few rotations of the scoring reel, it will finally energize the 100 pt score reel.

Player 3, works correctly. When 10 pt score reel gets to nine switch, it energizes the 100 pt reel as it should.

Player 4, same as player 3.

Biggest problem.......when the spinner is activated and the 50 pt switch is hit it resets the machine. Or, if any other target is hit that gives multiple pulses and then another is hit before it completes it pulses the machine resets. Resets everything back to zero for all 4 players and also tries to kick out a ball. The only thing that doesn't happen is it does not advance to the next ball......so not doing a full reset I guess. Again....this only happens when the 10pt relay is involved. To try to make this less confusing, basically any time there is a switch hit that gives multiple points in 10's, there is a chance the machine is going to reset.

Not sure if all this is clear. I'm in a holding pattern....not sure my next direction. All tips / advice is appreciated. Hoping someone can relate to some of this. Thanks.

The game over relay stays pulled in......does not change during the reset.

Just went down and simulated it several times with the playfield up. The reset relay is energizing. I did notice that it did not do it everytime, however it did reset probably 8 out of 10 times when I simulated it. Maybe more than that.

Will do. I'll report back after work today.

Update. I cleaned and checked A switch on the reset relay. No change. What would be the next "go to"? What would be causing the relay to energize just because (2) point switches are hit at the same time (or time it takes the ball to travel from one to the other). Again, it only resets if the score reels are still turning when the ball hits the next switch.

Did the test. With the card in the switch, the machine acts really strange, gives points at the 1000 and even the 10,000 reel. Acts like it trying to do weird things....score reels jump. Seems like its still trying to reset.

Forgot to say, the reset relay is still getting energized.

I'll get to it this afternoon after work. Update to come. Thanks!

I'll load pictures of the reset RE, GO relay, and the coin relay. Anything else?

I placed a piece of paper in switch C on the game over relay and tested....no change. I then took the paper out and placed it in switch B of the coin relay. Again, no change.

Somehow that reset relay is getting energized to reset the machine. Could it be a switch on the scoring motor since it is occurring when the scoring motor is running? Thanks.

That is correct. In fact, if I hit the switch on the side that pulses 50 points and then hit a roll over switch near the ball drain that pulses 30 points, the game resets as well. Basically, anytime a 10 point switch that is hit and pulses along with another 10 points switch being hit while the first is still pulsing, it resets. I first noticed it after hitting the spinner as if you hit the spinner hard it will spin several times pulsing the 10 point switch several times. I had hit the spinner then it hit the pulsing 10 point switch on the side. I know I may be confusing you.

The ball count does not change and neither does the player. It just resets the scoring reels to 0 and tries to kick out another ball.

Yes, if I hit something that scores a multiply of ten and hit another switch that scores a multiply of ten before the first is finished scoring, it resets. Does not change the ball count or the player 1, so not a compete reset.

yes, I have a DMM.

Yes I am getting continuity between the black wire and the other wire on switch A. No continuity from the black wire to the switch stack bolts.

One thing that's confusing to me about pinballs, seems like you get continuity everywhere. I checked continuity across the entire relay with the black wire and I seem to get continuity on all of them. I also did the same thing on a couple other relays with the same results.

Problem solved..........one of the switches on the score motor was out of adjustment. Thanks for all of the tips and help!

I placed a piece of paper between the bottom 2 leafs on the 4 switch stack on the impulse side (second from the end) The paper was actually between the base leaf and the leaf above it. I tried to recreate the problem and it worked as it should. I believe the leaf above the base leaf was hitting on a rivet on the base leaf. I took the entire stack off and adjusted the base leaf. Could also have been that I ensured all the switches were straight when I reinstalled them. (possibility that 2 of the solders could have been touching). But at any rate, the paper test took me to the area that it was occurring.

Yeah, not sure either....remember it was the bottom leaf of the bottom switch that I believe was making contact with the rivet on the base leaf. I wasn't smart enough to figure it out, I was advised to do the paper test.
