My NGG has had a reset problem for quite some time.
I've replaced the rectifier diodes previously, which didn't fix it.
I just replaced the capacitors at C8,9,10,11 and 12.
Good news: I can activate both flippers without the game resetting.
Now when I turn the game on, 50v fuses 103 and 104 blow. 102 is fine (coils 9-16).
Nothing blows with the J133 connector unplugged.
Any ideas on where to start looking? It doesn't seem like the capacitors I just replaced would have an impact on the 50v.
