    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?

    I think these hacked up wires are supposed to go to the J3 connector.

    it's hard to see where the wires are going to, there's one underneath that appears to be a ground hack.

    can you remove all the plugs, J1, J2 & J3 and post clear pics with wires separated/not bundles so as to possibly advise further?

    I really would say: It's the other way round. I havn't seen a single piece of this board surviving until today without any of this sort of hack.

    Just some examples:

    Haha! Holy cow. I guess my issues are pretty minor.

    I must be lucky; the only issues I have run into is some toasty/burned GI pins.

    I can supply you with more photos of hacked Bally rectifier boards...
