Engine fuse blowing - alternator wiring going into plug doesn’t look great (the Green/White wires are barely hanging on) (going to start there first), but I figured I would ask the forum of experts if the wiring looks correct. Thx

Seems ok. Definitely get some new connectors for the wires. The plastic housing can be reused if it isn’t brittle.
@Coolerman has connectors and housings. Look for bare spots in the wires that could be shorting out blowing your fuse. Also make sure there is nothing hanging behind your gauge cluster. I had a temp sender wire that ran behind the cluster and was touching the back of the ammeter and blowing my engine fuse.

your white ring terminal wire is grounding out on the F E N spade terminals where the plug goes in your pic ?

Your white/black stripe looks odd. Maybe you need to Sumitomo Yazaki that ground

Thx all for the responses - I will check back after I do some work. Matt I’ll be in contact.
With the alt disconnected does the engine fuse hold and start fine?
I was having the same problem, PO had done some wiring on the alternator and one of them was crossed. Turned out I don't think my battery was charging either lol

yes another reason I’m doing this is because my battery is not being recharged while running - with the engine running I pull the Neg battery lead off and the engine wants to die - telling me the alternator is not working correctly. Leads me to think he wired it wrong AND I’m addressing blowing fuse at the same time. Thinking it’s not a coincidence that they are both happening. Thoughts Anyone?

OK
RED FLAG Here
stop time to tweek the chain of events a tad
- you got alot going on , mayber too much ?
you could have indeed fryied your alternator , its a low cost rock auto type unit , to be very clear i AM NOT being snarky just stating information
- you need to pull of that alternator and have it manually bench tested as your nect cruicial step in my professional opinion
this was you will know 2 Concrete facts not easily diagnosed buy you in fading winter cold twihlight
- 1 : your unit is working normal and doing it job , then you can move on and concentrate valueble time diagnosing the correct nest steps
- 2 :: your unit took a dump , then all you have to do is reach around back and pull out wifes CC ............exchange out a nice fresh unit
- there is ZERO guess work here allowed , you cant take and waist valuable resources
and I always sleep better st night simply knowing i left NO TEq stones unturned
please consider the proscribed steps
would be mine exactly if i were you
bench tests are free usually
just my :

Just following my eyes from alternator wire through engine and bam! - spotted this too .. lol 
The wire your looking at is across the engine block to the right under whatever this K&N filter charger thing is for and the air compressor/arb power unit for compressor/lockers

Is that a natural splice by the factory? Going off to the headlights...I think not by the way I’m just curious what the e heck I’m looking at here - I ran my eyes along where it going and uncovered as much as I could and it was headed toward my front left headlight
