Thanks, had another go at the 3 way point today. All 4 solenoid coils are getting power, but they will only set the straight direction. One suggestion is that because it is a symetrical 3 way point, when trying yo set the left or right direction, the two sets of point blades try to move, but because they are moving against each other the point will not change. Anyway, I’ve removed one of the 3 way points from the layout and one of my more electrically competent friends is going to try and get them working.
