Andrew - have you contacted Rottendog to let them know ? It could be a manufacturing or QA issue than needs to be sorted out ?
+1.
Jim seems to be quite resonable to me, always goes out of his way to help me,
when I need to ask a dumb question 
I will contact them.
but as i said the original bally boards needs the inputs to the board to be pulled low to activate the solenoids, also the new revision of the rotten dog board needs the inputs to the board to be pulled low to activate the solenoids. on this rotten dog board all but 3 inputs work as i have mentioned on the two other boards but the remaining 3 need to need to be pulled high to activate the solenoids
