Does the Outhole relay fire when the ball is in the outhole?
Space Time Outhole relay (resized).jpg
Once a game has started, the sequence should be:
- The ball in the out hole closes the normally open Outhole switch to close
- That causes the Outhole relay to fire and hold in its active position
- The Outhole relay starts the Score Motor turning
- the Score Motor causes the ball to get kicked into the shooter lane
- the Score Motor 10A switch opens which lets the Outhole relay relax
- the Score Motor stops

I've seen this before in a 4 Million BC. I chased it down at the time and convinced myself that the wires weren't necessary. Notice in your photo that you have an unused Score Motor switch too that doesn't appear to have ever been soldered. It could be that they shared wiring harnesses or switch stacks between games that were similar but just slightly different.

The extra wires are for games with e.g. more complex coinage options, quite common in Bally EM games. No need to worry about those.

You don't have your location setup on your account. Where are you and maybe someone local can help.

The best way is to be methodical, patient, and logical. Use a solid understanding of how the machine works combined with analysis of the schematic to attack problems one at a time, and you can get it working. The schematics can seem very complex and intimidating, but in the end they are actually logical once you understand them, and even though they are big it is really can be broken down to a bunch of smaller circuits with various jobs.

You can try out my thread here to get some background of how the schematic works. It turns out that this Space Time is a similar vintage Bally machine, so even though they aren't exactly the same, the schematics are very similar in many ways. Many of the concepts in this thread will apply to your machine.

It is best to take things one at a time. The first thing to deal with is this: something is off with the startup sequence. Let's see if we can figure it out. The schematic is online at the pinball database so I have it. Next we have to get the problem(s) defined so that we can understand everything, then attack it. You have to get the startup sequence working correctly first and then go from there.

Are you putting coins in to get credits, or has this been modded for free play?

Either way, when you press the credit button, these things should happen:

- The score reels reset to zero.(If they are all at zero, manually advance a few of the reels to some random number so you can check this. If you don't know how to manually advance the score reels, check back for advice).
- The total play meter will advance by one (you have to observe it underneath through the open coin door).
- The ball count unit will reset, so you will be on ball one.
- The player up unit will reset so you will be on player one.
- The game over relay is energized, so the game over light should go off.
- The ball will be kicked from the outhole.

You already said the ball is not kicked out at the end. Do all of the other actions work as they should? These are all tripped by the score motor, so the score motor should be going through a cycle or two while this all happens, then stop.

Look at the bottom right corner of the schematic and you will see that these are all connected through one common element which is score motor switch 7B. That switch is NO or Normally Open. It needs to close when the score motor makes a turn in order for any of those kicker solenoids to work, so that’s the likely culprit, either that or a wire associated with it. You will need to get in there and check the adjustment of that switch. I believe it should be the second one for the top for #7 on the score reel since it is switch B.
