Check this circuit for good contact and cleanliness.

What about the make/break on the Outhole relay? Check sw. C.

Hi seanduffy
implicit (implied ?) currieddog asks "Does the Double-Bonus-Relay pull-in and stay pulling when the feature "Double-Bonus" should run / take place. Greetings Rolf

Hi seanduffy
(most likely) the Double-Bonus-Relay has two threebladed Make-and-Brake-Switches. Toggle-off, unplug the main power cord (Safety Reasons) - when You manually actuate the relay: Do these M&B-Switches actuate properly ? Greetings Rolf

This switch on the motor may be gapped too wide

For a switch to work 3 things are necessary
1) When open, there should be a small space between the contact points (duh)
2) When closing, the long blade's contact point should push the short blade's contact point enough to move the short blade
3) The contact points should be clean, which they usually will be if #2 is happening

Hi seanduffy
single bonus works in Your pin - see the upper half of the JPG - stepping down on the Bonus is fast (Score-Motor-5-IMP-B) and also the making 1000s of points is fast (Score-Motor-5-IMP-C) --- five times per turn of 180 degrees (half a revolution) - synchronuous stepping.
Both the stepping (synchronuous) on double bonus should be slower - around half speed - see lower half of the JPG. When the "switch encircled red" is faulty - means still there is connection to Score-Motor-5-IMP-B: The Bonus-Unit is fast stepped down - the making points is "half speed" - the feature ends when the Bonus-Unit is stepped down completely. Greetings Rolf

Check the related sw. on these two relays? I also see that sw. C on each of the A, B, and C relays is tied into Double bonus.

Hi Sean
where are You at problem-solving ? I struggle with understanding the logic of sequence in reality in the pin / in the schematics. I do have the four Player Space Mission - similar but not identical sections in the schematics. Today I tried on my pin "working with Test-Light(s)" - but I messed up, got false results, must do it again - but need daylight (and this has gone by now). In the JPG I show in the schematics what (alike) I wanted to test in my pin. "D-B means Double Bonus action", "S-B means Single-Bonus action also does simply shows 'pulsing five times on a turn of 180 degree (of the Score-Motor)' ".
I do have some "SteveFury Testlight"s - see https://pinside.com/pinball/forum/topic/reading-gottlieb-schematics#post-2634425 two cheap 12Volt-car-bulbs put one behind the other sums up to 24Volt-Test-Light. See in the JPG how I wanted to hook on my Testlights.

My problem of understanding, top of JPG --- in the schematics of Space Odyssey it says "Bonus Unit is stepped down on 4th and on 5th pulse (compared with the pulses 1,2,3,4,5 on the Impulse Cam) - On the points the cam 2-L does suppress some of the Impulse-Cam pulses. I do not yet understand.
With some imagination I partly understand "Space Mission" --- Bonus-Unit is stepped down on pulse-3 and on pulse-5. If I let suppress (in my imagination) the cam-2-L on the first pulse I'd then have "1 is suppressed, 2,3 give points and 3 steps down the bonus-ladder --- 4,5 give points and 5 steps down the bonus-ladder". This is a nice hypothesis but does not match with the drawing of Cam-2-L ... So I wanted to use my Test-Lights to learn about " what pulses does the Cam-2-L suppress - but I messed up.

Sean - anyway: Test-Lights are a good tool - want to buy some cheap 12Volt car bulbs and make You some Test-Lights (?). I hope within some 24 hours I can write about results of "my testing again having daylight".
(((Of course - as usual: The Double-Bonus-Relay (especially the solder-lugs on the relay) in my Space Mission is/are hard to get at))) Greetings Rolf

Hi Sean
what I do write here about my Space Mission is not much help on Your Space Odyssey - the interesting stuff might be wired different. I call for owners of an running Space Odyssey to look up in their pin and write about.
See the JPG "my Score-Motor" - there are some switchstacks with an off-set (red dot, blue dot) but the Cam-2-Long-Dwell (green dot) does not have an off-set (in my Space Mission). I did use my Test-Lights to find out about WHAT pulse(s) of Impule-Cam is/are suppressed by the actuating of motor-2L (?). I did not really see it so I toggled-off the pin, unplugged the main power cord (Safety Reasons), lifted the motor on one side (on the left in the JPG) and slowly turned the motor the way the motor runs on its own --- watching the timing / actuating of the five times on Impulse-Cam and the actuating of the suppressing cam-2L. The result I show in the second JPG - it is "fake drawing". On Double-Bonus my pin steps down the Bonus-Ladder on impulse-3 and impulse-5, 1000 points I get on impulse-1, impulse-2, impulse-4, impulse-5 (impulse-3 is suppressed by switch on cam-2L opening). I hope for help from an owner of Space Odyssey. Greetings Rolf

Any updates on this?

I’ve been doing a lot of schematic reading while working on my Space Mission logic lately. The double bonus was a little bit of a mystery as alluded to by Rolf above - from the schematic drawing of the long dwell cam, it seems like it would only open up for two of the five impulses (causing it to fire the 1000 pt relay on the other three impulses). But clearly it works .. so is the long dwell actually open for three impulses? I’d love to see a comparison of the actual cams (or a graph showing the toggles) relative to each other. Wonder why they didn’t just use a combination of other cams (kind of like Super Advance on conservative setting).

Anyway, it’s a curious issue indeed. Without knowing more about the exact cam timings, it almost sounds like it’s missing one of those two impulses (although I’m not sure realistically how that could have happened). Probing around with a test light seems like a good next step .. luckily you’re already zeroed in on the right area.
