When the target is hit, the relay pulls, but won’t engage the Ball Release, but will eject the Ball when I manually push the relay. Not sure what this could be caused by?

How is your bonus unit? Does it rest in the 1000 or higher position?
Because when you hit that target to release the ball. The sequence is that score motor operates, first the bonus is awarded (but bonus unit doesn't reset), then the ball is ejected from the saucer.
So maybe a false bonus unit position can disturb this?
Bonus Target is the relay that lights up then when target is hit, it is supposed to engage the Bonus Relay that ejects the Ball.
It could be a contact on your 2nd ball relay too. If that one isn't closed or making contact, and your target is hit.
It doens't activate the sequence for the bonus award and kick out.
Check contacts on 2nd ball relay, the activating relay when you hit the target and the bonus stepper unit.
Quoted from PinballGurus:it is supposed to engage the Special Relay
I don't see a Special Relay on the schematic, do you?

Let me check. Thanks for your help.

I have the Bonus unit set to off. But I did try manually cycling thru to see if I could get it to kick out, but no luck.
Quoted from PinballGurus:I’m looking at the 2nd ball now.

Care to explain what you mean?
I actually got the hole eject working by turning the Bonus Unit to a different position. Not sure what this does though? I made a video.
The Bonus Score Relay is doing this now?
At this point I’m pretty sure you’re right. Any idea what is causing it based on the video above?

I got it fixed last night. It turned out to be a contact on the Bonus Score relay for the Ball Release that wasn’t making contact (hard to get to). I ended up pulling the unit out and checking it over. I’ll add a photo soon.
Now the only issue I’m having is I cannot seem to get the Player Unit adjusted properly. If I tighten the clock spring and other springs just right I can get a perfect one player game, but it won’t advance to player 2. If I adjust it to where it will actually go to the next player it has a habit of skipping balls and won’t advance to player 1 after player 4. When I manually engage the unit, there seems to be a hitch in the movement that isn’t allowing the reset solenoid to reset to the next player, etc. or whatever it is. I’ll attempt to make a video of what it’s doing next. I checked the coil stops and they are both in good shape and both coils fire.
I appreciate your help.

Here’s what it’s doing now. Randomly not counting drained balls. I’m assuming it’s the Player Unit causing this...??? I doubt it’s the Ball index.
So even with the Ball Index pulled it will occasionally/randomly skip balls. Any ideas? I’m assuming it’s the Player Unit at this point. Does anyone agree?
The Ball Index pulls when points are scored but doesn’t always release when the Ball is drained, which is what appears to be causing the skipped balls.
Any ideas what would cause the Ball Index to not release randomly?
Perhaps it’s not the Player Unit after all?
Anyone know what would cause the Ball
Index to not release on occasion? Is it just an adjustment on the Ball Index relay?
The point relay switches initially send power to the ball index relay coil. Check the following:
10 point relay switch - white/brown wire and yellow wire
100 point relay switch - white/brown wire and yellow wire
1000 point relay switch - white/brown wire and yellow wire
Make sure these switches are clean and adjusted properly...
That makes sense. I’ll do it. Thanks.

I think that stepper is missing a spring. Since it's a 4 position stepper, you can compare it to another stepper on the machine, like the coin unit. These steppers will advance three times to a different position via the step up solenoid. Then it will reset back to the first position when the reset solenoid is energized.
It looks like the spring you're adjusting is damaged and it will need to be replaced. These springs are not designed to be adjusted...
I replaced the coil stops. Both coils measure as good. Sounds like I need new springs. Anything else?
It "looks" like the player unit stepper is working properly when you manually press in the solenoid plungers. I would push in/release the step up solenoid plunger quickly one time and then pause for a few seconds, and the then push in/release again to see if the disc will properly click into each position. Do the same thing with the reset solenoid plunger - push in/release quickly one time.
From the video, it looks like the reset solenoid plunger is working properly mechanically. When you release that plunger, it will release only half-way. When the step up solenoid plunger operates again, it will make the reset solenoid plunger move out to its full resting position.
From the game play video, it seems like the player step up solenoid is working, but the player reset solenoid is not energizing during the game. Set up a 2 player game again and play the ball for the 1st player and then play the ball for the second player. Then go to the player unit and look at the player reset solenoid plunger. If the reset plunger is still in its full resting position, then the solenoid is most likely not receiving power. You can manually push in/release the reset solenoid plunger to see if that will get the game back to player 1, ball 2... If the reset plunger is half-way in the solenoid, then there might be a mechanical issue with the stepper... Here's a video of a Bally stepper in action:
