I have an issue with EBD, the outhole kicker does not have enough power to serve the ball into the shooter lane. Any and all suggestions welcome and appreciated.

However, when I manually short the transistor tab or coil lug to ground it works fine. (I do this by putting the game in lamp test so that the expansion “lamp” is lit which also pulls the relay on for the solenoid expander board).

Here is the video that shows the three tests, and two slow motion videos of the mech firing in normal test mode.

What I have tried:
-new outhole kicker solenoid (AO-26-1200)
-Reduced spring tension on solenoid kicker
-cleaned and bench polished kicker mech, new coil sleeve.
-Rottendog driver board
-Alltek Mpu
-Alltek lamp driver board
-Repinned J3&J5 on driver board
-Gulf Pinball Power Supply Board
-Gulf pinball solenoid expander board
-Repinned connector on expander board
