Battery terminal bolt seized.
#16
Yes it is bolt #1 thats seized. I had the terminals completely free of the battery. Even had the battery removed at one point. I used a vise wrench to hold the bracket portion of the terminal while i tried to break the bolt loose with a socket. Nothing! Wont budge.Trying to keep the cable stationary while turning is also an issue because theres nothing to brace the cable to with battery removed. I may try grinding the bolt off with a grinder. Not sure how it got so seized.

Judging from the severity of corrosion, I'd suggest to replace the cable as it's very likely that corrosion has propagated into the cable under the jacket. The positive battery cable is just a short run away (see diagram below) into the J/B immediately in front of it.
You will have to open the J/B to get to the connection. Take a look at this post to see how to take the J/B apart.

You're welcome!
You mentioned before that you can remove the battery from the car. One thing you can try is to soak the entire terminal assembly into a cup of baking soda and water mixture. Let it sit for about 5-10 minutes and then see if you can brush the corrosion off. You may have to repeat the process a few times. The baking soda solution will neutralize the corrosive action, and as long as the metal parts are not severely pitted, you may not have to replace anything (and thus eliminates the need to break free the seized bolt/nut). The key is to stop future corrosion. I brush on some dielectric grease to all exposed metal to prevent corrosion.
