No power in the car

Hi guys! Byron's girlfriend. Helped him take a look. Switched power source to the alternator showed no voltage. Found up and inspecting the fusible link showed no visible damage. The power wire going to it from battery had 12.5 volts. I remembered I jumped the ammeter wires due to having a no power condition earlier. Crawling up under the dash not only did the voltage was a wimpy tenth of a volt, but the wires showed this :

Sorry for the crappy image. But clearly the wires on the one stud shorted, resulting in melting of the rubber. And it was horribly rusty and corroded to begin with, and that poor connection must have been the "fusible link". We are in the process of pulling the gauge cluster right now. (Good time to fix everything else, you see that duct tape?) I'll check the bulkhead, hopefully those contacts did not get melted. Thank you for the web page, that was very helpful!
