I have quite a few issues on this one. Not sure where to start.

1. Cannot start a 2 player game.

2. Will not go to game over after ball 5.

3. Gate to shooter lane will open but closes right away.

4. The 100 point relay will stay energized longer than I think it is supposed to when only 100 points is scored (can hear it buzzing). When 500 points is scored, it works much more smoothly. The scoring in general is confusing me. (If I manually move to player 2, same behavior is seen).

4a. 100 points scored when targets are lit and not lit, 500 points scores when targets are lit and not lit. Seems random.

4b. Spinner triggers the 10 point and 100 point relay...what the Hell? Sometimes 100 points per spin sometimes 500 points per spin. This is in addition to 10 points per spin. So confusing.

Where should I start? I do have the schematics. I can usually use them to figure out the problem if I know what to look for, which I don't.

*I have cleaned and adjusted the 100 point relay and I THINK it's ok.

Some good places to start. Thank you. What about the scoring? What are the spinners supposed to score?

So hours later and zero progress made...why do I do this to myself? Lol. I don't think the shotgun approach is working for me.

The 100 point coil will hold too long sometimes. When it does, game will not score 500 points. Just a long hold of 100 point relay and 100 points. Also missed points in pop nest as instead of 100 points per pop it's 100 points per 3 seconds or so (however long 100 point relay is pulled in).

Sometimes (Usually ball 4 or 5) 100 point relay will work just fine. 100 point relay pulses instead of holding. 500 points will score fine, all pop hits score 100 points, etc.

Just looking at this one issue (so I don't loose my mind) where should I look? What would cause the 100 point relay to hold instead of pulse like it should?

Are those normally closed switches in the red boxes on the score reels?

Thanks so much for your time and help. I will dig in and report back. Thank you!

So...I have cleaned both EOS switches on both 100 point score reels. Problem still remains. I let the score reels hang down while scoring 100 points so I can watch them in action. EOS is wide open after plunger is pulled and 100 point relay is still active for a few seconds! Any other ideas?

Yes. It stays active even when I block that switch on the 100 point relay.

Progress! I just went through the entire relay bank and lots of adjustments were needed.

I can now start and play a 2 player game!

100 point relay is now working as it should!

***At the end of the game (ball 5 drained on player 2) instead of going to game over the motor just kept running.

***The ball return gate still won't stay open. It opens and closes right away. Adjustment to the shooter lane switch made no difference.

On a roll now. Misadjusted switch on outhole relay was keeping it from going to game over. Fixed!

2 things left for now.

***The ball return gate still won't stay open. It opens and closes right away. Adjustment to the shooter lane switch made no difference.

***First ball for player 1 will only score 100 points (no chime) even if ball rolls over 500 point upper rollover. After any switch is activated, all scoring works correctly.

Ideas?

ZB (1st ball relay) doesn't fire until a switch is hit. Is this correct behavior or should it fire at game start? Wondering if this is the issue?

That's what I gathered from the schematics but what's weird is the first switch hit does not activate the chimes regardless of score value and the lit 500 upper rollover only scores 100 points (again with no chime) when it is the 1st switch hit. Once any switch is hit and the ZB relay trips everything else scores correctly...

Asking for more help on my scoring issue. I cannot get the 1st rollover to score 500 points until any other switch is hit 1st or I hit the 1st rollover for 100 points 1st.

The only relay I see that stays active after the 1st switch closure is ZB 1st ball relay. But that is correct behavior for that relay.

Here is the schematic.

G is the 500point and add bonus relay. #1 top rollover is the switch in question.

Fixed! Was a normally closed switch on P that wasn't closed.

Last issue is in the previous post. Any help is appreciated!

Boom! Got it! Make or break on SB1 not making. What a rush figuring this stuff out while listening to some good music (punk rock) in my shop!
