the truck goes dead after a day or so, with gauges going dead, radio going dead, lights refusing to go off, etc. Shop replaced battery, checked alternator, said everything seemed to be fine. Same problem three days later and has continued. Has the original alternator, but is charging according to the shop. The truck will run fine for a day or so, but then seems to go dead in a few minutes, including trying to die while idling. I need to get to the bottom of this and get my reliable truck back.

with vehicle running check the voltage drop from the alternator to the battery.
