81 Wiring Alternator Help
Hello, I am new to this part of the forum. I recently purchased my first squarebody, an 81 GMC K2500. Due to a recent sale of my DD, I am in a hurry to get this thing running consistently. I have killed a battery or 2 (I'm not very mechanically inclined, but learning) and have done the voltage tests on the battery and have confirmed the battery isn't getting any charge. Atleast up to 2500 RPMs. So I need a quick fix to get the alternator running. It looks like to me that the battery charge post (?) on the alternator isn't connected to anything. See attached photo below. There is a loose red wire just hanging there. In theory if I hook that back up it should work correctly, no? Or, for now would it be possible to run a 10-12 gauge wire from the battery post straight to the alternator? Should I fuse it? I apologize if this should be in electrical, I'm just hoping to get it sorted out. Thanks in advance.
