with the vehicle off and the battery charged, disconnect the negative battery cable. Take an amp meter and connect it between the cable and the battery post. if the reading is high, pull fuses one at a time and check to see if it changes the reading. Another thing to check is your alternator regulator by full-fielding the circuit and checking the output

Try a new voltage regulator.
