I am trying to get my Space Mission up to 100%. There are 3 final things I am trying to fix.
Score reset on 4th player 1000s reel. After cleaning the switches on both the reset relay and the reel a hundred times and trying to sort this out, I ran a jumper between the "0" switch on the reel to the lug on the coil and the reset seems to work fine. My question, is this a hack or a valid fix? I can't figure out why there is no wire that goes through this switch to the coil. It seems like on all of the other reels this is so. I couldn't find continuity from this switch to the lug like on the other reels. Maybe it is a 40 year old wiring mistake? I find no evidence of a wire missing. The wire seems to go from the switch into the wire bundle and back towards the player unit.
No 4th player option from the start button. I cleaned up the Coin Disc contacts and took it apart and cleaned it, and can manually make it go to 4 players. When I press the start button it starts player 1, then on a second push it starts 2 players, third push 3 players, and then I push the start button and NOTHING happens. No score motor or coin relay movement when trying to start 4th player.
When I drop a quarter in the coin slot (either slot) the score motor runs continuously and credits are added until it is maxed out. The score motor continues to run until I turn the machine off and restart it. It looks like the 25 cent Relay is locked on.
Does anyone have any input on these items? Thank you!
