If anyone that has a DH would check in their switch edges test and pull the trigger. This is switch 11 on the matrix. When I pull mine it also activates switch 12 on the matrix but there is no switch associated with this on DH. I get the little dot all the way to the left on row 2 when switch 11 is activate. This happens even when I pull the J207 and J209 and short the 1 pins together so playfield is eliminated. Just want to see if anyone else's activates the dot on row 2 so I can eliminate other issues.
The issue I am having is I keep getting switch 44 gun chamber switch credit dot. This switch checks out in the test. In game when the gun is loaded to start multiball it rotates slowly as it should. When I pull the trigger it starts rotating fast and the ball never gets shot out. I have logic probed the circuits for switch 44 and swapped in a new ULN2803 bu no changes. That is when I noticed the issue with the switch 12 being activated by the trigger button. I socketed and installed an LM339 at U18. No changes.
