My space mission has been working fine. It has always done a weird thing where when it starts and the score reels reset... even if players 2-4 are all on zeros... some of the 2-4 reels (100s and 1000 I think) also spin around in unison. They all eventually stop and everything is reset. Why are all these reels moving when it should only be resetting player one? No issues in in scoring while playing.

Yup that did it. Thx! There were so many reels doing the same thing that I thought it might be something else.

Can you answer another schematic question for me? The points rollover 100,000 light on the backbox randomly will turn on for player 1 and 3 sometimes. It still turns on like it should when going over 99,999 but sometimes it is lit at the start of the game.

Also, the player turn 1-4 lights sometimes work and sometimes don't. They are either all working or all not.

Can you direct me to the switches I need to clean or adjust for these things?

Thanks I got it! Just 2 more questions...

I took the 100 unit score reel (3rd player) out to clean something off it and now it doesn't work at all. Like nothing. When you try to play a game with player 3 - and hit a 100 pt target on the playfield. The 100 pt relay activates and holds and wont let go until it moves on to the next player. As long as it is on zero, everything resets and the game starts and even all the other reels on player 3 work... just not the 100 reel. I looked at the wires and nothing looked loose.

Also, the Shoot Again light on the backbox goes on and off. There are two lamps that light it and I dont think they both can go in and out at the same time. Seems like another switch I need to find.
