I first posted here about a month ago and had some very helpful people direct me to some beginner's resource material. I've checked these out and have been trying to educate myself to the point where I can begin to talk (semi) intelligently on this forum. I'm hoping that I'm at that point now.
I'm trying to breathe the kiss of life back into a Space Odyssey machine that's been dormant for many years.
I've taken it about as far as my limited knowledge allows and am looking for some guidance on what type of things I should be looking at next.
I've done a lot of visual inspection on all of the switches (while manually activating the relays, solenoids, etc.).
I've also rebuilt the 3 main stepper units (which definitely needed it!) and am 99.9% sure these are functioning normally now.
The status of the machine right now is as follows;
-Powers on and most lamps light up (I haven't yet started testing/replacing bulbs - waiting on a parts order).
-Credit unit steps up when I manually activate the coin door switches.
-When I press the START (reset??) button at the front to start the game, the credit unit steps down, the RESET and COIN relays activate and the score counters reset to zeros. At this point, none of the scoring functions, flippers, bumpers, etc. are working.
-If a ball is present at the drain area, the description above applies plus the score motor rotates continuously and the BONUS relay activates once per cycle (twice per revolution).
That's where I am right now. I'm hoping some generous soul will have pity on me and give me some direction on where/what to be looking at next. I've got a fairly strong background in electro-mechanics but none of it on pinball machines. With limited time available to dedicate to this, I'm finding it a bit overwhelming to get into it further.
Any help would be most appreciated. Thx in advance!!
