Woopsies while rebuilding passenger side alternator (GEN 2)

[Enforced_Leo44]

Hi everyone,

For a while my gen 2 light has been flickering when at idle, the flicker was erratic. Did a bit of research and the first thing that came up as a cause would be the voltage regulator so I decided to replace it.
Got the part, took off and apart the passenger side alt, replaced the regulator and put everything back together. Alternator is back on the truck, went ahead and connected the positive terminal of the front battery and... it sparked and a good amount of white thick smoke came out of the alternator. Disconnected the batteries quickly, took apart the alternator again and found what caused the smoke, and that would be the solid core copper wire that goes from the regulator to the rectifier (I think?). The insulation melted off because when I tightened the regulator mounting bolts, the eye terminal of said wire shifted towards the alternator casing (of course I did not notice this happening) inevitably making it short out with the rest of the engine and chassis.

Re-placed the wire, making sure that it was properly protected, insulated and distant from any ground (i guess those are all synonyms), put it back on the truck and... the Gen 2 light doesn't come on when ignition is on.

So... I know that I probably f'd up the alternator itself, I'm gonna take it apart again and test all the internals, my real concern is wether I f'd up something else in the electrical system because of that short.

Gen 1 and oil light do come on, I did some research before posting this and read about the 10amp 24v fuse on the fuse box that could be blown, but I checked it and it's good (even though in my truck it's a 15amp, probably someone in the past had some beef with 10amp fuses)

Before starting to overthink all of this, I'd like to hear everyone opinion, did I just trash an alternator or could I have possibly burned something else up?

EDIT: some typos

I'd bet you just need another regulator. The only wire I can think of in the alternator is the capacitor. I'd check for the power going into the regulator, though, to see if you blew a fusible link. I'll look at one when I get home.

The regulator gets power from the 2pin plug, right? I just check for 12v going to those 2 pins with the key on?

yes...there's a good check in the sticky in the forum for what to check too.

Also, there’s a orange wire/fusible link that connects together with the positive lead at the alternator, B+ post, where does it go and what does it connect to?

I'm asking this because it snapped right at the black cylinder that's on it, which I guess it's some sort of interference suppressor. I'd like to know wether I can just put some random piece of wire there or if it has a specific purpose

Apparently the internal capacitor of the passenger side alt was also cooked... is it needed for the charging to take place or is it just there to prevent noise to the stereo/radio system? If so, can I discard it and get going?
