You may have fried the alternator, napa and some other stores should check it for free. Also make sure that the connections going into the voltage regulator aren't corroded, and that field, stator, etc. are all connected where they should be, and that no wire is overlooked.

Look at the large post on the solenoid where the battery + wire connects. Under this large wire should be a smaller wire or wires. In this smaller wire should be a colored rubber thing in the wire. This is a fusible link, and it's probably burnt out. Pull on it and if it stretches, it's probably bad. The store has new ones.

Check for power in the fuse box. If there is no power there at all, your problem has to be out at the solenoid area that you looked before. Will your headlights work? If not, that points even more to a power problem out at the smaller wiring feeding from the solenoid, feeding power to the truck.
