Picked up 2 complete games, but been sitting for 15+ years according to the seller. Anyways, picked the better of the 2 from all the components (cabinet, head, playfield, relay board) and made one good clean one. got it all plugged up and it's working...ish. aside from the small things, the first big things I noticed are as follows
1) ball count never ascends. it always stays lit at 1. if I go on the relay board and manually rotate the spider by hand, or even trigger the coils manually by finger; it works. both coils check above 2 ohms. When rotating by hand & it gets to ball 2 and it just keeps spinning the score motor and cam, resetting the playfield, and if I click it again to ball 3; it stops going bazerk.
2) when on single player for "number of players", it still advances to 2nd player, 3rd player, and 4th player on the head by the score reels, but stays lit as 1 player on the lower right for "number of players". play 1 ball through all players and once player 4 is done, it doesn't advance back to player 1; just stays on player 4, so player 4 could keep playing as many balls as they want.
3) each and any player only gets 1 ball to play before advancing to the next player.
any suggestions where to start or what area to work on first?
