I’m working on a Skateball with the early Bally AS2518-18 rectifier board. I planned on replacing it but it has some weird hacks going on that I want to figure out 1st.
It has one thicker red wire and one thick orange wire and one thin orange wire coming out of the wiring harness and soldered to Test Points 1 & 3.
It also has a thick green and a thick white wire from the wiring harness soldered to the bottom face of the rectifier board.
There is also wire soldered from the bottom of the capacitor just above fuse F1 to the ground point on the solenoid driver board.
Anyone see this sort of thing before?
