Seriously? The one that you've been told to check multiple times by 2 people.

Couldn't get my multimeter to work on the wire... it was just showing 0.L when I put the one lead on the connector that shows battery voltage on the voltmeter, and the other lead on the starter terminal. (Slightly bent the pin trying to keep the lead on the alternator connector) But while I was messing with that, I cleaned off the two chassis grounds (didn't look bad) and I fiddled with the battery to starter wire that had some blackening at the terminal and the plastic covering the ring connector was chipped off. So I took the rest of the plastic off the ring connector, wire brushed it a little, and tightened the three nuts on the starter and put it all back together. Now it's doing it every start, throwing code p1637. Do you think me messing with the battery to starter wire set it off more meaning that's the problem?

I was told to check a few wires. But I'm assuming you're talking about the one in the harness that is supposed to get battery voltage. Checked it today, and I couldn't get any kind of steady voltage. Bounced around from mV to .7v... rechecked the big power wire to make sure I was doing it right and it was steady at 12.3v. Used the same ground for both. So next step would be change the fusible link? I'm not exactly sure what it looks like and where I'd get one. Electronics aren't my strong point with cars, so I'm learning as much as I can as I go.

the fusible link is rather obvious. It's a piece about 6" long attached spliced onto the end of the wire. You can tell it's different then the rest of the wire.
You can check a fusible link by pulling on it. If it stretches then it's bad.
You can get a piece of fusible link at NAPA. You'll want a 20 gauge piece. You probably broke it completely when you worked on the starter terminals.
Get some double wall heatshrink tubing to cover the new connection splice you make.

Alright, let me asknow a weird question then. I found the fusible link I believe. Bought some replacement wire and was going to do it but it started raining. But i did notice that two wires seemed to be connected like an h pipe connects an exhaust. Is that normal and should I leave it alone? I'll try to take some pics when I can.

And if you look closely here, you can see where the two fusible links were stuck together:

First pic shows just a broken ring connector. Second pic shows a fuseable link at the top of the pic, but impossible to see damage.
Good job finding it.

Yeah, first was the culprit, second if you look in the middle to the left of the brown wire, you can see the other link. They were stuck together pretty good
