I am trying to figure out if my FH blanking circuit is working correctly. LED D19 comes on at startup but only for like half a second. After it goes off some of the low power coils occasionally fire for a few seconds (especially if the game is cold). I compared to my Fish Tales and it's blanking circuit stays on for a full 3 seconds but I can't be certain they should be the same since it's WPC-95.

Hey John,

Thanks, didn't realize Fish Tales was that old.

Seems coils 09-16 are the culprits, those are the only ones I've seen fire during startup. I guess that may eliminate the blanking circuit as it would probably cause other coils to fire as well? Looks like they all share U4 on the power driver board but I didn't want to go shotgunning parts without having a good idea of where to start.
