Default good alt, empty stud 2000 bonneville

I replaced the motor in my 2000 bonneville sle non super charged. As i brought the wireing harness and started making all the connections everything matched up and lined up perfectly. No connection for the empty stud on the back of the alternator coming from the wireing harness. I had the alternator tested twice. Once at an alternator starter shop, and again at autozone. Both tests declared that it working fine. The car will only run until it drains the battery dead. Autozone and the alternator shop both said the empty stud feeds the battery. The alternator has a three wire plug. I cant remember taking anything off the stud during disassembly. The stud looks like it never had anything on it. I assume if there was a connection for it, it would have came out of the wireing harness next to the plug. I am completely stumped. Any help is greatly appreciated.

i dont have a 2000 but i would assume since the battery is in the back you should have a big wire that goes to a terminal stud to distribute the power where it needs to go. regard less yes you have to have a wire there so you need to find yours.

You should have a big (heavy guage) wire red in color. That goes on there.

Default found the wire!!

Found the wire, after pulling it out from between the valve cover and the coils, i tucked it into the fender wall. It looked like just another wire dissapearing into the body... embaressing! But now I am back to my original problem. The car still wont start with the key. I had jumped the terminals three or four times friday night and then it started all weekend as i needed to move it, i found the wire and hooked it up, I am getting good voltage back to the battery now. Now, it just wont start with the key again. The saga continues......

Thanks again for all of the help gentleman. I really appreciate it!

Default car starts again!

bonneville starts with the key again. for the second time I've unhooked the battery, did some work, hooked the battery up and it wont start with the key. after turning the key multiple times and jumping the terminals to start it, it decides to start with the ignition key. is it possible the the system is relearning or something along that line after unhooking the battery ? thinking about giveing it a female name like stephen king would!!!
