Try reseating all the connectors on the sound board and the lower left connector on the driver board. The lower left connector on the driver board is where the signal is sent to the sound board to tell it what sound to play.
You should plan on reflowing solder to those connectors (might be a bad connection there) or actually reflowing solder on all the header pins on all the boards. Games from this era are prone to bad solder joints on header pins.
Which side of that coil has the banded side of the diode? The dual wire connector should be on that side.
Quoted from Pintor:Is the banded side the side in the right in the pic? The end of the diode with the metal?
Thanks!
Based on those 2 pictures, you had the wires reversed on that coil. Connecting it up that way basically makes the diode a dead short to the driver transistor which will blow a transistor in a heartbeat.
The diode could have survived but no way to tell without testing it. Better just to replace it like the others have suggested.
Also, if you haven't ordered already, get 10 or 20 of them. They are used all over pinball machines.
