I took your advice and had cut the diode prior to install. It works now, but only with the A2.17 set to yes.
With A2.17 set to no, I won games via score, HSTD, and special, and no knock, no twip.
Strangely, I set the match percentage to 50% and had to complete 8 games before it matched. Odds of that are 1 in 128, or black coming up 7 times in a row
before a red at the roulette table.
The knock isn't classic Bally/Williams "THWACK" loud, but way better than the twip. I'm going to experiment with different knocker assemblys.
I'm going to do my IronMan now (S.A.M. system) and will document both of these methods in the PinWiki.
