Hi all, finally managed to sort out a problem on my Big Show which has been baffling me for about a year now! It was always 18 that spotted and never the 2,all the wiring and relay circuits checked out fine and magic squares stepper all cleaned and working. It was only by chance that I was looking at the diagram of it with the wiper unit on the bench next to it I realized one of the fingers was in the wrong position and would always trip the 2 or 18 relay too early resulting in 18 always spotting after ABC lit. After a little 'modifying' I managed to get the wiper in the correct position and reassembled. Hey presto it worked and now it spots the 2 sometimes! I wonder if it's been like that since 1956-who know's? Morale of the story-check everything!
