Would someone with access to an Old Chicago be so kind as to identify the mech board relays for me? The one I'm servicing only has a couple labels left.

1- ? _ Score
2- 5K Bonus Hole
3- ?___
4- Does not exist: counted a gap
5- Over the Top Delay
6- ?__ 500 Point
7- Target Down
8 & 9 - Game Over Interlock

10- 2 ?___
11- Coin
12- 2nd Chute
13- 3rd Chute
14- Credit
15- Lock
16- Reset
17- Delay
18- Outhole
19- Ball Index
20- Tilt
21- X ball
22- ?___
23- ?___
24- 3 Coin Unit
25- Ball Count Unit

Now I am questioning the reference photo on IPMDB for Old Chicago's mech board as the pic doesn't match what this game has. I only need 4 relays identified:
Left column, last one and third to last.
Right column, last two.

I will be able to figure it out eventually but was hoping someone could help me out. I'm making new labels and don't want to remount the relays until I get the labels stapled down.

Any OC owners out there?

Give these a shot. If you need more high res let me know

Hey, bintzknocker, these are GREAT! I think they will fill in the gaps entirely. Awesome. Now I can re-create them and get them stapled while I have the mech board out for servicing. Lots easier.

No problem.

One question. What is the first one on the right side? The second one is COIN, then 2nd CHUTE, 3rd CHUTE, etc.

What's the first one? It has a wire over it.

Ah, 2nd COIN SET UP. Thank you so much for the pics. That relay coil has a brown/yellow wire and I couldn't match it on the schem...63 I think. Anyway you saved me a lot of time and effort. It is greatly appreciated!
