Great Guns Driver board problem- schematic enclosed
So my solenoids in the guns are being constantly energized as soon as I apply gnd and +5v to the driver board.
Here is the schematic, looks pretty simple but I cant figure out why.
Both solenoids are energized. I have disconnected the input from the game PCB and the problem remains. As soon as I disconnect the +5 or ground to this board the solenoids relax.
Thanks!
