I have a NBA fastbreak where the backbox ball/coil fires only when the pass 3 coil fires.

I orginally had a smoked coil on the pass 2 coil . I replaced the coil and put in a new transistor.

Now the backbox coil only fire's when the pass 3 coil fires.

The backbox ball/coil used to work before I removed the board to replace the transistor.

I think I plugged everything back in correctly but I guess could have missed something.

Short on the board you worked on ?

Next up, figure out wire colors for the coils and follow to driver board and look for errors.

It doesnt always fire at the player 3, but if it fires, that is the only time i fires...
