I have a Bally 'Delta Queen' that seems to be almost running, but I'm having trouble with not getting any points when the center saucer is lit for 5000 points:

When the ball goes into the saucer, it is recognized. The 'Center Hole' relay energizes, the score motor turns, and the ball is kicked out of the hole - but no points are awarded.

I'm trying to trace through the schematic in an attempt to figure out why the 5000 is not being awarded. I'm not understanding how the 'Center Hole' circuit is linked to a 5000 point award. Any help would be appreciated.

So there are two saucers on this game: 1) the 'Bonus Hole' and 2) the 'Center Hole'. From the schematic above, I see how the 5000 RE. switch associated with the 'Bonus Hole', but it doesn't seem to be associated (again, I could be reading the schematic incorrectly, the answer might be right in front of me) with the 'Center Hole''.

Here's part of the schematic concerning the 5000 point relay:

I just don't get how its all linked together... I can manually enable the 5000 point relay, so I know that's working as I'm awarded 5000 points. Again, the 'Center Hole' saucer eject is working... just not being awarded any points.

Here's the whole schematic:

Thanks in advance for any help!

Quoted from Studentprince:

Have a look at the schematic at about 29 G to H. Score motor switch 2E pulses the 1000 point relay 5 times.

Studentprince - Thanks for pointing me to the correct place in the schematic. I just jumpered across that circuit and now score 5000 points. Its a bounded issue now to find the intermediate problematic switch. Thanks again!

@Miguelcerca... There was a problematic switch in between the two test points. I don't remember exactly what it was in the end but the smart people on here helped me out and are now helping you too
