when starting a game , everything works perfect except that the score reels for player 1 and player 2 do not reset to zero
The score reels for player 3 and 4 behave normally.
During playing scoring works perfectly ok for all 4 players but the score for players 1 and 2 keeps adding up since it does not get back to zero on start of game.
I did clean Z1 relay and looks ok. Have not checked it for continuity though.
