Alternator Wiring Noob Please Help

Hi, I've got a 1972 240z that I've been refreshing and I decided to change the alternator.

I bought a duralast alternator from autozone and am having trouble with the wiring. Installed the alternator and messed up the wiring somehow. after rewiring it I reconnected the battery and the fusible link burned up. I've got a new one from MSA and want to make sure my wiring is correct before I burn it up as well.

I have used the search function but couldn't find anything clear enough. I also looked the the FSM and couldn't make heads or tails of the wiring diagrams.

I am a complete electrical noob and would appreciate some help.

Here are a few pictures of what I'm working with.

B stands for Battery. The thick white wire with the red stripe goes there. E stands for Earth, also known as ground. The black wire goes there. The T plug plugs in to the same hole as the other alternator, the one with S and L beside it. The thing that looks like a small can, the condenser or capacitor, looks correct in your first picture.

That should be it. If you were having over-voltage problems it may be that the original issue was with your external voltage regulator. You'll find out when you get the alternator installed.
