Quoted from CUJO:Ok, shorted Ground TAB on Q13 to game gnd for a few milliseconds which caused BANK #3 to reset.
So not a coil problem.
I pulled the driver board out of the game and tested the transistor and it seems to be ok.
In diode test, I get .494 on each outer leg to the ground tab.
That sounds correct, granted the others test the same way. In some rare cases, they will test okay but are still internally failing. They're cheap enough to replace, may want to just shotgun replace it if you have one and see if it fixes the issue.
