Repair Instructions

  1. Battery Replacement (if faulty):

    • Disconnect the negative cable first, followed by the positive cable.
    • Remove the battery hold-down bracket and lift the battery out.
    • Place the new battery in the tray, secure it with the hold-down bracket, and connect the positive cable followed by the negative cable.

  2. Repairing Parasitic Draw:

    • Once the high draw circuit is identified, troubleshoot the components:
      • For Interior Lights: Check for stuck switches or malfunctioning bulbs.
      • For Door Switches: Ensure they are not sticking when doors are closed.
      • For Aftermarket Devices: Disconnect or replace any faulty devices.

  3. Alternator Repair or Replacement (if necessary):

    • Remove any components obstructing access to the alternator.
    • Disconnect the negative battery cable, then disconnect the wiring from the alternator.
    • Remove the alternator mounting bolts and lift it out.
    • Install the new alternator, reconnect the wiring, and secure it with mounting bolts.
    • Reconnect the negative battery cable and check output voltage.

  4. Final Check:

    • After addressing the issues, recheck the parasitic draw and ensure it is within normal limits.
    • Confirm that all systems are functioning correctly and that the battery holds a charge.
