I don't think the C6 was offered in '92 F150s. Click this, read the caption, and fill in your signature:

The PW circuit doesn't have a fusible link; it uses a self-resetting circuit breaker. And when a fuse or fusible link burns, it STOPS that circuit from draining the battery.
This would be easier to understand if you told it chronologically. Why did you replace the alternator, and with what (source, brand, PN)? Same questions for the battery. Why did you want to replace a wiring harness section? There isn't one from the alt. to the battery (-) post. How did you choose a 30A fuse? There are 2 fusible links on that truck; one carries ~150A peak; the other peaks over 200A, so it's not surprising that a 30A fuse blew quickly. Don't modify the wiring system if you don't understand it - repair it, or pay someone who understands it to repair/modify it.
Are you saying the battery drains when the truck is turned off? Have you measured battery or alternator voltage when the truck is running?
