No + voltage at B terminal on alternator!
The SA suddenly has lost it's Positive voltage at the B Terminal post on the alternator side. It's currently running an S5 alt too, so now there's a huge drain on the battery.
I'm currently just running a jumper from the positive battery post directly too the alternator's B terminal. This lets the car run, but the battery still gets drained after a cold night.
And just to be sure, the Black wire with the eyelet that bolts onto the Alt's B Terminal should see a 12 v+ with the car off, right?
And what is likely to be the cause of the wire not having voltage? I need some help on this pretty badly.

The B terminal should have voltage even when turned off. It is a direct connection to the battery's Positive post. If you do not have voltage, then you have a bad wire somewhere. Start tracing. I don't believe the stock wiring has a fuse in there, but who knows for sure. Maybe a burned up thermal link if you still have them.
