Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, battery load tester, basic hand tools (sockets, wrenches), safety gloves.
Safety Warning: Disconnect the battery before working on electrical systems.

2. Clean and Secure Battery Terminals

Remove the negative battery terminal using a wrench.
Inspect for corrosion; if present, clean the terminals using a wire brush and a mixture of baking soda and water.
Reattach the terminal and ensure it is tightened securely.

3. Repair Parasitic Draw

Identify the component causing the draw by pulling fuses one by one while monitoring the multimeter reading.
Once the offending circuit is identified, inspect, repair, or replace any faulty components (e.g., switches, modules).

4. Battery Replacement (if necessary)

If the battery fails the load test or is older than 5 years, proceed to replace it.
Remove the negative terminal followed by the positive terminal.
Remove any securing bracket and lift the old battery out.
Place the new battery in the tray, ensuring it is oriented correctly.
Reconnect the positive terminal first, followed by the negative terminal, and secure the battery.

5. Final Checks

Start the vehicle to ensure that the electrical system operates normally.
Verify that all lights and accessories are functioning correctly after repairs.
