Happy Saturday guys, I'm replacing some sockets in my Bally Strikes and Spares board and some of them are tied together, is it necessary to do that on the new socket too? It seems like the obvious answer is "yes", but why would they do that in the first place? It looks like some of these don't even make a connection to anything.

Diodes are cheap and easy to replace... If it was mine, I would replace it. Also, some of the pins on U8 look like they are barely making contact because of the corrosion or the decaying solder, if they are currently working normally, that is. It is a problem just waiting to happen when you never expect it and least want it to fail.
Yeah, I'm starting at the worst part on the bottom and working my way north on this board, U8 wasn't nearly as bad but replaced that too after an acid bath. The game was in a garage for 12 years when I got it - some lights worked but it never actually played.
This is my first serious foray into board repair, did all the recommended cap and header pin repairs and ground mods on the driver board and that went fine (Thanks for the guides Vid). Battery corrosion is another animal though, I'm finding, some of the traces and pads are lifting on the first header I'm trying to replace. And, I can SEE surface corrosion on lots of things but does that really mean they are bad...i will replace that CR44 diode, thanks. I hate to surrender and just get an Alltek board, I'd like the satisfaction of bringing this back from the dead. I'm going to keep at it.
Quoted from Tuukka:The bridges tie CMOS RAM data in and out together, which is OK for it to connect to 3-state data bus.
But as said, looks like there is severe battery damage, so try to neutralize the corrosion before installing new sockets.
Thanks, I gave it an acid bath and rinsed w water then 91% alcohol prior to installing the new sockets. Wish I'd taken a couple more pics to share but before I knew it I was halfway done -
I got this game in August 2018, and, my actions being dictated by Michigan weather, started with the cabinet first. Sanded and stenciled it. Moving to the play field this summer, sanded that down, put on an overlay and clear-coated it ( 5 coats to level the thing, learned a lot there), started replacing parts. So this winter, the final piece is bulletproofing these boards and reassembly.
