I'll get to it. I have a spacelab that worked until recently which I am sure is a normal statement for pinball machines.

I am following this sequence:

When the start button is pressed, the credit unit is decremented. This is done through the credit unit zero position switch and the 2nd coin relay (and the ball count zero position switch).
The end of stroke (EOS) switch on the credit unit decrement coil will energize the coin relay.
The coin relay will trip the game over relay.
The coin relay will energize the reset relay. The score motor will run.
The reset relay will energize the ball count unit reset, through the score motor.
The reset relay energizes the 2nd coin relay latch and game over relay latch coils.
The reset relay will energize the score reset relays, through the score motor.
The score reel reset relays will zero the score reels, through the score motor. The score motor will continue to activate the score reset relays until all the score reels reach the zero position.
The reset relay activates the bonus unit coil until the bonus unit zero position switch is activated.
When the bonus relay drops out, the outhole relay is energized through a different bonus unit zero switch and score motor switch.
The outhole relay will run the score motor. The bonus unit will step up once. The ball will be kicked to the shooter lane.

The last step is my issue:
The outhole relay will run the score motor. The bonus unit will step up once. The ball will be kicked to the shooter lane.

I have found other posts where the outhole switch is not working properly preventing the ball from being kicked out. I have tested and cleaned this switch to ensure this is not the issue.

I have bypassed the lock relay with a basic manual override for the time being.

The machine:

Resets score, bonus, ball count
When it gets to the outhole relay the relay just cycles rhythmically in time with the 5th cam in the score motor
This is where it is stopping
It does not add the S (first bonus) to the board. The bonus will clear if I manually add bonus letters before restarting.

I have included a video

I have exhausted my troubleshooting ability to where i am getting a little spun out on sources of the issue

Any advice appreciated I will follow steps and see if something I missed stands out

Thanks
