An alternator requires excitation voltage or it just won't put anything out. If the battery is dead the alt won't put out nothing. If you had a generator the gen will charge up the 100% dead battery but an alternature wont If you hook this puppy up wrong you will cook it or the regulator or both. The regulator also needs to sense the alternator voltage so there should be one more connection for this to work. The alt will work without any regulator at all but it will toast your battery. The alt output goes to the bat and reg bat terminal. I think the STA goes to the regulator sense terminal. Hook up the sense lead and it will work fine.
