Sounds like the alternator is bad. Start the truck, and while it is running, you can test the incoming voltage with a multimeter. If you do not have a multimeter you can remove the negative terminal. If the truck quits, you need a new alternator. If it keeps running with the terminal disconnected your alternator is fine. But if you replaced the battery and the cables, then I would be pretty sure that the alternator is bad.

Sounds like the inline fuse popped. It is located in the wire that comes from the alternator to the battery. The alternator is sending out the juice, but it can't make it to the battery. I sincerely hope that this gets you on the road again. Best wishes and God Bless.

First remove and clean battery cables and battery posts with a wire brush or sand paper. Make sure battery is charged and check to see if it starts. Then check battery condition and charging system. The problem could be cables, battery, or alternator. Check them in order and repair or replace as needed. Check cables, battery, belts(tension and condition), and charging system in order. Do this because bad cables will give false readings for other tests and so on.

In the PCM is where the Horn Relay is. It's location should be annotated on the underside of the cover you pulled off to gain access. One way to determine if it is the Relay or not is to find a similiar Relay (shape and size) and switch them. If this fixes the Horn problem it is the Relay and should be replaced.
