If the transistor still tests good perhaps it's not really shorting out but when you replace it something gets temporarily changed that hides the problem for a while? You could rig in a switch in series with the coil and hang it out the coin door, play till it locks on then quickly flip the switch to open the circuit and keep from frying anything then test the whole circuit in that state, briefly flipping the switch back on for very short periods if required. I did something similar on JP when I had it and couldn't figure out which coil was locking on before the fuse blew (turned out to be the raptor pit). Good luck!
