First thing, all four work the same way so if all for are not working we should look for something in common. But let’s start simple.
So to get No# 1 to flip, we need to make sure the No#1 flip Relay is not energised and then close the No#1 target Switch, this should energise the No#1 Target Relay, and in turn energise the No#1 flip coil.
So Below, the red line happens first. We close the target Sw, than though a Sw on the #1 Flip RE with Orange/Red wire and Grey/Yellow wire, this should energise the #1 Target Relay and it should stay on by its own hold sw (Purple line below).
Now the #1Target RE is energised , the Target RE SW (Green line) is closed, at least should be. Then we go thought the #1 Flip RE Sw Grey/Red wire and White/Blue wire, energising the Flip coil.
Hope this is as clear as mud, but let us know what you fine, and we will take it from there.
