This was not “obvious”. Obvious is something you glance at and go “ah I see it”. This one took diagnosing a problem (thanks again @quench), deeper review of the schematic, checking photos of other connectors to make sure I was reading the schematic correctly (not my forte), counting pin numbers, and THEN I got to say “ah I see it”.
I have repinned thousands of connections at this point. I agree it’s a worthwhile endeavor most of the time and I DO repin most games that pass through my hands. To Quench’s point, I don’t necessarily sit there and double check the schematics for the pin locations when I repin (unless the connector is damaged or looks tampered with). Especially on Bally’s where it’s pretty obvious if it’s an original connector or not. I snip the wire, crimp the connector, and insert into the new housing in the same location.
On this one, the pins were holding very firm, visually very clean, good continuity from pin to wire end via multimeter check, and on a board that is rarely unplugged. It’s the unplugging and plugging that raises the need to repin… or general corrosion, filth, etc, which wasn’t present on this game. I’m confident it would not have been necessary to repin this specific connector if someone hadn’t shown up drunk in 1982.
