Quoted from PinballManiac40:I only ever add jumpers if the related through hole to both sides of the board look sketchy or has an issue. Otherwise, seems like overkill and it makes me think when I look at a board with all these jumpers that someone did a lot of damage taking parts out.
I agree!!! The Kahr daughter board is wonderful. Had power down resets on my Indy 500 and thing of the past now. Thought about adding to all my games to avoid future issues.
