I think you have some electrical corrosion/problems , look for anything obvious or get a technician , Not a job for Johnny jerkwrench

Follow the wire from the alternator to the battery. On the firewall on the passenger side of the truck is a black 175 Amp fuse for the alternator. with the truck not running check both side of the fuse for battery voltage. I've seen those fuses blow from not disconnecting the battery when changing alternator.
