This is not just replace the wire and all is good, these fusable links need to be there that is what burnt up. From looking at your vehicle tag the alternator has been off of the vehicle at least once. Check the main plug on it (black one), the piece that folds over on it and tabs onto the regulator on the alternator may have a crack in it. If this is the case it is probably vibrating loose a little bit and causeing a short. This is a common problem with all ford alternators that use this style plug, they are very easy to crack and cause problems down the road. You can buy a replacement pigtail from ford for around $15-$20. Most wont have one in stock but they should be able to get it fairly quick. Also the ground strap that runs by the oil filter (braided), go by your local Autozone and get a new one out of there help section, befor you put it on get some liquid electirical tape and put a good few coats on it this will help it last longer down the road. The 4.6 motors are bad about fraying this strap when the Motor mounts start to go bad (engine torque over). Let us know how it turns out.</p></blockquote><p></p>
