Hi everyone, I have a S076 that I've owned for almost 20 years that has started giving me problems. Up until now, it's been rock solid with zero problems but one issue that came up recently with the Double Bonus countdown at the end of a game has now turned into multiple issues.

The problem started off with the Double Bonus light only coming on dimly for the last ball. I check the bulb, all good, and then determined that the LB relay was not pulling in all the way. I cleaned and adjusted, and that solved the problem.

Then, while playing a game shortly thereafter, I noticed that the bonus countdown wasn't accurately scoring. It was adding more to the score than it should have. I traced that down to a janky switch in the "E" relay which then solved that problem. I confirmed the Bonus was now scoring correctly in all scenarios.

I played a few more games and everything was working perfectly but then I noticed that at the end of a ball, 10 points was being added to the 2nd player score reel, even though the game was started as one player only. Weird.

Then, upon starting another game, the ball stopped ejecting into the shooter lane. I did some searching and checked switches on literally every relay on the bottom board to make sure they were all set correctly and all NC switches were making good contact, but my problem still persists.

I also checked and cleaned the zero-position switch on the bonus unit. I did the same with the P5A and P5B switches on the Player unit. Neither of those made any difference.

Here's what happens: I press the replay (start) button and everything resets as it should - all score reels go to zero on all players, motor stops spinning, ball 1 shows on the backglass, but the ball doesn't eject.

Now, if I manually activate the "O" relay, the ball return (eject hole) fires, so it seems that particular relay is not firing when it should. While testing, I also discovered that when I trigger a playfield switch to score 10 points, the 10-point chime coil stays stuck on and no score is registered on the score reel. I'm guessing this is a related problem? The 500 and 1000 playfield switches register correctly on the score reels, so I don't have an issue with those.

I'd say I know my way around the game but I'm no genius when it comes to reading schematics, so I could really use some help here please.

Thanks paulace and DaMoib. I did check the AX and most of the switches highlighted in red, but will check again. This is very helpful, thank you. I'll dig in again and report back with my findings.

Update - I used a jumper and traced the ball eject problem to SL+WH switch on the "J" relay, so THANK YOU for your guidance regarding the schematic.

Now, I still have the 10 point problem where I trigger a playfield switch to score 10 points and the 10-point chime coil stays stuck on and no score is registered on the score reel.

I also noticed that after ball #1 finishes , the ball ejects but the game is not advancing to ball #2.

Any ideas are appreciated.

Hi @paulace, thanks for the info. So far I found the switch on the 10 pt score reel that wasn't opening, so the "N" rely is no longer locking on and the 10pt chime is working correctly, but the score reel is not registering the 10 points. Is that another problem switch on the score reel itself?

I'm out of time today but will follow your instruction for fixing the advance to ball #2 and follow up here. Thank you again!

Hi @paulace, I was able to fix both of the remaining issues with your clear explanation regarding the schematics, and I can't thank you enough!

The BL-YEL switch wasn't making on the "N" relay, so cleaning and adjusting it now has the 10 pt score reel registering points again.

The ball not advancing was a bit trickier to solve, but once again the way you explained how to follow the path to the Add Player Unit helped me narrow it down. Your advice about listening to the player unit was spot on (there was no movement), and it turned out to be an open switch on the "P" relay.

Now the game is back to perfect working order. Thank you so much, I am very grateful for your help!
