actually they go to the positive post on the starter relay/solenoid, but essentially straight to the battery.
and no, a 4gauge wouldn't go from that post to the neg terminal. you could run it to the pos terminal if you wanted to gaurantee charging. those 2 blacks have an inline fuse at 140a i believe

ok cool, ill have to try that out tomorrow, that might be why the car isn't running at 13+ volts while running. Just so I understand correctly, essentially as it sits, the alternators (+) that it is producing(the rear bolt post) is going straight to ground?

ok I was just out with my multimeter and tried connecting that rear post to the positive and it didnt change the batterys voltage at all. I did meter the two black/orange wires and they are hot(12v). Im going to bring the alternator in and have it tested when I go buy the plug that I need for the new alternator.

final update, got the plug and alternators tested. The bosch was in fact dead and after wiring the duralast one up everything is working great. Thanks to all who helped.
