Check your connections and cables

sounds like you need a new set of battery cables or there is something drawing alot of power off the battery when the truck is off and it shouldnt be drawing anything

mike37

so you have a short

others have had the plug for towing short and cause your problem
look for loose or worn wires

some times the alt will have a short that they don't test for it will still charge fine but kill the bat after the motor is off

if you have a voltage tester disconnect the pos battery cable and connect the
tester accost from the cable to the terminal it should be showing voltage if you have a short

then un plug the field wire from the alt if the voltage stops then you have a bad alt

Might take battery to Auto zone or Walmart and battery tested with a high rate discharge tester to see you have bad cells in battery
