I fixed the coil with the broken contacts and now the score reels are working properly I think,but the drop targets, kick outs and stand up targets are not scoring,almost thought the chimes were going to work,heard one chime and that was it. It seems that sometimes I have to reset the AX and other times I don`t. Only first ball is lit up now,does not advance any further,but keeps serving the ball. The coil that had the dodgy contacts in the head box is also making a buzzing noise almost like shooting sparks sort of noise,but no sparks...
