Changed back to "In Progress", as I thought I better go through the backbox and learn more about that side of things.
I think working a little on the old CPU made me hanker for more understanding.
I had a connector that I could see had been cut up and a connecting block added with a different kind of 3 pin connector
I'll zoom out a bit, so you can see the orange wires come out to a connecting block onto the bigger yellow wires with a blue jumper.
Removing the connector uncovers shinnanigans. But I can see what's going on here, so that's cool.
I guess it burnt? Someone didn't have the right 12 pin connector to hand, so chopped things up a little bit. I do worry about dicking about with this header, after seeing the through-holes disappear on the CPU PCB giving no conductivity. Wouldn't want the same to happen here.
I need to find a header for this. Surprisingly tricky at the moment, but I have a spare connector on hand already.
J115 is the GI, goes to GI fuses on the board, connects up to J120, which also has some jiggery pokery, look like this plug also had the last 2 pins chopped off and a quicky 2 pin connector used. I'll clean that up too if I can. Put a new connector on there.
Question, if the board is on the bench, do I replace the caps while I have it off? They don't look particularly bad so why replace something that ain't broke. Other than, if it does, it's a ball ache later.
Dunno what to do about that one
