Recently acquired Stern EM Disco pinball game. Few issues I had to work thru with unresponsive playfield, typical gummed up steppers etc.
Anyhow I got everything working and the score motors were sticky. Removed player one score reels, cleaned and put back in place. Ran thru a few games and all worked well.
Started two player game and all worked well but the two player score reels were all sticky. Game ended, turned off machine, removed first score reel (do one at a time and test) from two player side, cleaned, put back together and tested. Now when starting a game it keeps going thru the reset sequence (single player/can't get into the two player feature because its stuck in reset sequence). All player one reels reset as normal but the game just keeps looping.
Start game relay stays engaged. If I manually pull it open the ball ejects and game plays fine.
I've rechecked the score reels and all looks good. For the life of me I can find the problem. Is it a coincidence that this just happened after player 2 reel was cleaned? During 1 player game does the 2 player reels also have to reset?
At a loss here and could use some suggestions.
