Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked in a safe, well-ventilated area.
Allow the engine to cool before working on electrical systems.

2. Disconnect Battery

Use a wrench to disconnect the negative terminal (-) first, followed by the positive terminal (+).
Safety Warning: Always disconnect the battery before working on electrical components.

3. Clean Battery Terminals

Remove any corrosion from the battery terminals using a mixture of baking soda and water.
Rinse with clean water and dry the terminals before reconnecting.

4. Test and Replace Battery

If the battery fails the load test, replace it with a new battery of the same specifications.
Ensure the new battery is fully charged before installation.

5. Identify and Repair Parasitic Draw

Use the multimeter to identify components drawing excessive current.
Repair or replace any faulty components or connections identified during testing.

6. Reconnect Battery

Reconnect the positive terminal (+) first, followed by the negative terminal (-).
Ensure all connections are tight and secure.

7. Final Check

Start the vehicle and verify that all electrical systems are functioning properly.
Monitor battery voltage to confirm the charging system is operational.
