So I changed it to a 10 gauge...

Also, 2 years ago I went through and redid all the wiring under the hood with new wire. I used a 10 gauge wire from the back of the alternator that connects to the starter and ties into the main power line to the fuse box and blower fan. My connections were all soldered.

With that said, after my testing yesterday it makes it a bit confusing. So I'm going to remove the connection from alt battery to battery "B" first and then go through the testing Clay suggested.

FYI, my voltage sensing wire on the alternator is a direct connection to the alternator battery post.

That should go directly to the battery, unless the wire from alternator battery post to the battery is very short.
