I have trouble with the drop bank of my Sword of Fury. Sometimes it work, some time it doesnt work.
When the target drop down, they are not taken into account in the score, and they stay down during all the game (someime they goes up after a long delay : a few minutes).
I have run an auto diagnotics and then all the 5 target solenoids are well powered and goes up during the tests.
It's probably related to the detection of the target drop down.
I have distmounted the Drop Bank, and check all the components of the board (mechanical and electrical parts) and also clean the optocouplers
and i still have the same problem. Some time it work and sometime not.
I refurbish all the connector welds of the drop bank boark but still the same issue.
Any idea will be welcome.
