Quoted from KW_pins:SOLVED- Dirty switches on the impulse cam of the score motor. I had previously cleaned all the score motor switches but on the impulse cam I cleaned between the switches not the switch contacts like a noob. It's working like a champ now.
Time to break down the PF, clean, wax, and replace the rubbers!
Thanks MarkG
I know this is an old thread, but...any chance you have a photo of where the impulse cam of the score motor is?
