my Genesis G70 battery keeps dying, what could be causing it?

Solution

1. Preparation

• Gather tools: multimeter, socket set, wire brush, battery terminal cleaner, ammeter.
• Ensure the vehicle is parked in a safe location with the engine off and the keys removed.
• Safety Warning: Disconnect the negative battery terminal before working on electrical systems.

2. Battery Replacement (if needed)

• If the battery is found to be faulty:
  1. Remove the negative terminal first, then the positive terminal.
  2. Unfasten the battery hold-down clamp.
  3. Carefully lift the old battery out of the tray.
  4. Place the new battery in the tray, ensuring it is securely positioned.
  5. Reattach the hold-down clamp.
  6. Connect the positive terminal first, followed by the negative terminal.
  7. Tighten terminals securely to prevent any loose connections.

3. Alternator Testing and Replacement (if needed)

• If the alternator is faulty:
  1. Remove the negative battery terminal.
  2. Disconnect the alternator wiring harness.
  3. Unbolt the alternator from its mounting brackets.
  4. Install the new alternator in reverse order: bolt it in place, reconnect the wiring harness, and reattach the negative battery terminal.

4. Parasitic Draw Repair

• If a parasitic draw is identified:
  1. Identify the circuit causing the draw by pulling fuses one at a time.
  2. Repair or replace any components that are drawing excessive current (e.g., faulty modules, lights that remain on).
  3. Recheck the draw with the ammeter to ensure it is within the acceptable range.
