ARRRRRRRRRGGGGGGHHHHHHHHH!!!!!
Well then, i did as you suggested Daniel, i manually activated the relay by pushing the arm and guess what!!!! It scored 1000 points!!!!!!!!!!!! WTF....
So i thought i was going mad and did it again.... 1000 points and not getting stuck... so then i hit a rollover and it moved the 1000 score reel AND the 100 point, sound like one of the score reels tried to reset itself and then the coil got stuck!!!!
WTF!!!!! grinding axe now
