I picked up a Dolly Parton some time ago and started working on it. I discovered that a previous owner did some modifications on it and wanted to find out if anyone knows what the heck they were doing. I'm not sure if they had attempted some sort of mods on the solenoid board and rectifier board, it's not pretty... My initial take is that I should figure out how the machine was originally wired for these two boards and take it back to the way it shipped from the factory unless there is a reason for some/any of it... I'll post some pics below. The first one is a drawing that I found in the coin box when I got the pin.
