Quoted from t2:I am getting credit dot saying "Turbo error sensor opto error" and don't know where to start. Manual does'nt list a switch #. I am never getting a multi ball in the turbo scoop the 3 green arrow that say Lock never lite up even after shooting up the left side. New to the game and not sure of the rules.
Also, be sure that the switch on the opposite side is making (above upper flipper). You must complete the loop and if it doesn't make, you will never qualify for a lock. I had this problem with mine when I first bought it (loose wire on the switch).
