The game shouldn't be energizing any of those solenoids at power-on. The diode, even if bad/misconnected, shouldn't do anything until the transistor turns on.
How did you test the solenoids on the bench? With the game off and on (with 2J11 removed), do a continuity test from the header pins to ground, make sure none have continuity.
Quoted from troxel:Added a circuit breaker to it, and now F2 blows on power up.
Was the circuit breaker rated the same? I'd think if you replaced a fuse with the breaker, the breaker should start blowing, not something else...
