So I had a perfectly working Spring Break, decided to move the machine from basement out to garage to make a little room. After re assembly of legs etc, fired it up and poof , smoke and burnt smell from boards.I lifted the playfield and found the A12-J3 connector had come unplugged from the transformer board (very loose fitting), and I assume pins had come in contact to the wrong terminals on start up. I also blew 2 1 amp fuses on the top front of the pf. The game will boot but several coils are locked on, the left drop target, the 2 lamps under the ramp,(theses are coil driven flash lamps) the knocker fires. I just started checking driver transistors, so far only found q13 to be bad and q56. Does anyone by chance have a list of driver transistor assignments?. I have a manual, but not very good at figuring out schematics. Thanks.

I should add if I remove the fuse for the coils, game boots and starts fine...
