OK so to make this as quick as possible (still going to be lengthy) I did an Sr swap, the engine was bad, so I had to put my Ka back in so I can drive the car until I get the Sr fixed.
When I got the Ka back in, the alternator wasn't charging and my tach, speedo, and coolant temp gauges didn't work. I've tried 4 different alternators, 2 batteries and multimetered everything.
Yesterday I discovered that my 75A fuse was grounding out. Skipping all the details to that, I have isolated that the 75A fuse is getting ground from the driver's side floor board fuse box.
Like so:

I found that the large white wire with a blue stripe is the one that has ground continuity. Traced it back here, and found that in the FSM it powers the 3 relays down here. Well the place where that wire plugs in is what's grounding it out.
It's the 2 big prongs on the top of the panel in the picture:

Those 2 prongs are what that large black plug clip into. They are supposed to be the hot side that feeds the relays. I need to know what would short out to cause them to be grounded out.
Can anyone help me?
One more pic.

OH! One last thing, I also pulled all of the relays out and checked them. All of them have continuity on pins 1 and 2, that was it. Also none of my fuses are blown...
